All about the Hib vaccine: effect and side effects. The most important vaccination. Why get vaccinated against Hib infection Instructions for use

Hib vaccination is a mandatory preventive vaccination performed before a child is one year old. This article will tell you what the Hib vaccine is, why and how it works in the body.

The Hib vaccination can protect a person from Haemophilus influenzae infection, which penetrates through the nasopharynx and, being absorbed into the general bloodstream, spreads throughout the body. This infection is especially dangerous under the age of five, and can lead to the most irreversible consequences.

Before we talk about preventive vaccination, its features and consequences; It is worth clarifying that a person, without knowing it, is a carrier of hemophilus influenzae b-type infection. The route of infection is contact, that is, from an infected person to a healthy person; however this pathological process may not reveal itself for a very long period of time.

The pathogenic bacterium does not at all interfere with the normal life of a potential patient, since in the early stages it predominates in the nasopharynx and does not move inside the body. However, there are those compelling and, one might say, pathological causes, which slightly change the prevailing clinical picture. The infection, penetrating the body, noticeably worsens general health and can provoke serious pathologies, in particular, swelling of the throat, pneumonia, blood poisoning, extensive damage to the joints, blood and myocardium. In addition, death cannot be ruled out, which is a consequence of meningitis worsened against the background of hemophilus influenzae infection.

This once again confirms the need for timely vaccination, which is mandatory in the Russian Federation and is performed at a certain age of the young patient. If your child is not vaccinated, he automatically falls into the risk group, that is, his chance of becoming infected from a sick person increases rapidly.

So you should definitely turn to an important topic in pediatrics: “Vaccination Act Hib”! What this vaccination is for is already clear; All that remains is to find out how it works for preventive purposes. Also important is information about contraindications, side effects And possible complications, because, as is known, the effect of the medicine can be in children's body the most unpredictable. The task of a caring mother: find out all the details, and only then agree to carry out preventive vaccination her child.

According to disappointing statistics, hemophilus influenzae infection affects children in 40% of clinical cases. And only 5% of victims are adults whose parents refused to undergo the required preventive vaccination in childhood.

Hib infection is very dangerous in a child's life. Vaccination must be performed at 2,4, 6 and 12 months according to the preventive vaccination schedule. Since certain difficulties prevail today with the free vaccine, very often the Hib vaccine is given later than the specified age. This is a completely normal phenomenon, but you should not hesitate to vaccinate: the sooner it is completed, the better for the child’s health.

However, this vaccination is not indicated for all children, and contraindications apply to patients who have had a severe allergic reaction after the first vaccination, children under six weeks of age and people who were ill at the time of vaccination. Otherwise, there are no restrictions, however, before carrying out this mandatory procedure, the pediatrician must conduct a thorough examination of the child and exclude any presence of a virus or infection in the child’s body. Only after this allows the nurse to perform the above vaccination.

In general, the procedure is painless and causes minor discomfort to the child, which disappears very quickly. Side effects worsen extremely rarely, but are represented by the child’s passivity, redness at the injection site (local reaction) and an increase in body temperature to 38 degrees. Allergic reactions on the skin are not provoked by the Hib vaccine, which is why parents agree to this procedure without fear or doubt.

The vaccinated child must be monitored the following evening, since all possible side effects worsen during this period. If the temperature does not rise overnight, then in the morning you don’t have to worry about a deterioration in your overall health. So there are a minimum of contraindications and side effects, a powerful therapeutic effect, and Hib vaccination is very popular in modern pediatrics.

If the parent is sure that there is no need for it, then no one will force him, and the local pediatrician insists on writing a refusal of preventive vaccination.

According to the same statistics, in the territory Russian Federation Hib infection causes a third of the clinical pictures with diagnoses of acute respiratory viral infections and acute respiratory infections, up to 55% of the clinical pictures of meningitis, up to 25% of pneumonia, about 20% various forms otitis in patients before school age.

If the decision is made by the parents and the doctor prescribes the Act Hib vaccination, side effects It is important not only to study the attached instructions, but also to additionally agree with the local pediatrician, and additionally read information on the topic on parent forums.

How many vaccinations, when and why should a child be given? Why are there more and more of them? What factors are the basis when deciding whether to vaccinate and when is it better to refuse vaccination? Parents must know about this and much more in order to protect their child.

To make the right decision and find the optimal approach to this issue, you must first understand the essence of the problem. Perhaps fears arise unfoundedly and are due to ignorance of the situation. So, if the doctor says that the ACT-HIB vaccination is planned soon, and what it helps with, mom and dad should definitely ask a specialist, and only after that make a decision on whether to have it or not.

Children under five years of age are exposed to Haemophilus influenzae. To protect children from widespread diseases, Hib vaccination has been introduced. The decoding of the abbreviation comes from the Latin Haemophilus influenzae, which means “hemophilus influenzae”, and “B” means its type (variety). There are 6 types in total: a, b, c, d, e, f, but B is the most insidious and dangerous.

Haemophilus influenzae is covered with a capsule on the outside. It serves as a kind of protective barrier against the effects of the body’s protective factors. This makes it difficult for immune cells to notice them. If you do not vaccinate your baby, then it is possible that severe forms of disease will occur. Pneumonia, bronchitis, sepsis, acute respiratory infections, epiglotitis and meningitis - all these diseases are caused by hemophilus influenzae infection.

To prevent a child from developing a Hib infection, vaccination must be carried out in several stages, that is, according to a certain scheme. The number of procedures depends on the age of the child and his condition at a certain time.

A child should be immunized for the first time at 3 months. Together with the administration of the vaccine against hemolytic infection, DTaP is also administered. Further, it is also introduced in parallel at 4.5, 6 and 18 months.

If you follow all the recommendations and carry out vaccinations according to the schedule, then it is possible to protect a 6-12 month old child from meningitis and pneumonia, which is especially important. At individual scheme this cannot be achieved, since the interval between vaccinations should be 1-2 months and growth defensive reaction fails to gain the required momentum on time. But the child will be protected when entering kindergarten.

After immunization, many parents are confident that their children will not get sick at all. Unfortunately, this is a misconception. The essence of the vaccine is to protect against the aggressive “B” strain of Haemophilus influenzae infection. At the same time, it can be extremely difficult and lead to irreversible processes. The incidence of otitis and bronchitis also decreases.

Sometimes parents are able to skip vaccination against Haemophilus influenzae due to the presence of several vaccination regimens and the question “Hib vaccination for what? "

How older child, the more active the growth of one’s defense against hemophilus influenzae infection. This means that if the first Hib vaccination is given to children over one year of age, the second and subsequent revaccinations will not be required. That is, vaccination involves a single administration.

Adults and children over five years of age have the ability to fight hemophilus influenzae infection. This is because they have antibodies to protect themselves. In this case, the participation of T cells is not required.

Before entering kindergarten, a child must be immunized, since 45% of children under five years of age are carriers of this infection. Children who are not immunized quickly become infected and suffer severe illness.

The need for vaccination is in a simple way transmission of infection: by airborne droplets, through saliva, toys, household items. But treatment is almost impossible, since the capsule prevents the penetration of the antibiotic to fight the infection. Making a diagnosis is also difficult due to the lack of testing material.

Based on the above factors, it becomes clear that vaccination against Haemophilus influenzae is the only method that can be used to protect a child.

The Act-HIB vaccine has side effects, which include intolerance to tetanus toxoid. An allergic reaction to vaccine components may occur. In this case, its repeated introduction is unacceptable. Sometimes an allergy to pertussis antigen leads to the same reaction to a component of the Haemophilus influenzae vaccine.

Just like any vaccination, it should not be carried out during exacerbations. chronic diseases, at high temperature and when the child's teeth erupt. At this time, the immune system is very weakened.

Immunization usually occurs in 2 injections. One consists of the AADT vaccine, and the second is Act-HIB. But you can avoid two injections by mixing two vaccines in one syringe. This is not prohibited by the instructions for use for both vaccines.

There are also multicomponent vaccines that combine several antigens. For example, “Pentaxim” and “Gexovak” contain vaccines AADT, Act-HIB, polio, and hepatitis B. These vaccines are purified and acellular, which in turn makes them easier for a child to tolerate during vaccination. In rare cases, you may have a fever and mild pain after receiving these vaccines.

Now this vaccination is not given to everyone, but on the recommendation of a doctor or at the request of parents. No one is able to decide for a child, except his parents, whether he needs protection. Therefore, it is worth thinking about this issue in a timely manner and deciding on a vaccination schedule in advance.

Hemophilus influenzae (aka Hib) infection - diseases (pneumonia, acute respiratory infections, bronchitis, meningitis, sepis, etc.) caused by Hemophilus influenzae - Haemophilus influenzae type b or Hib.

The bacterium is ubiquitous. Its carriers are up to 40% of children under 5 years of age and about 5% of adults.

Hib has a special protective capsule that makes this bacterium “invisible” to immune cells, which prevents the formation of effective and long-term immunity to it.

Haemophilus influenzae has record resistance to antibiotics, which makes the treatment of Hib infection extremely difficult even when using the most modern and expensive drugs. Treatment is also hampered by the fact that in Russia there are no available test systems for diagnosis and determination of sensitivity to antibiotics.

The infection is transmitted to children from carriers with saliva through toys and household items, and by airborne droplets - through sneezing and coughing. In some cases, the source of infection is parents and older school-age children.

All this is the reason that Hib infection in Russia takes a leading position in childhood morbidity and mortality, causing at least a third of cases of acute respiratory infections, up to 25% of cases of pneumonia, up to 55% of meningitis and about 20% of otitis in children under the age of 5 years.
The only way to reliably protect against Hib infection is vaccination.

Why is Hib infection dangerous specifically for children under 5 years of age?

The Hib bacterium is covered with a protective capsule of a special polysaccharide, the molecule of which is too simple for T-lymphocytes to react to it. For this reason, the formation of immunity occurs “half-heartedly”, without the participation of T cells, which leads to the development of antibody concentrations insufficient for protection in children under 5 years of age. In children 6 years of age and adults, antibody-producing cells are already capable of forming adequate immunity on their own, without the help of T-lymphocytes.

In addition, children 6-12 months of age who are formula-fed and do not receive small additional amounts of maternal antibodies in breast milk are at especially high risk for the most severe forms of Hib infection—pneumonia and meningitis. For this reason artificial feeding is an additional indication for vaccination against Hib infection, starting from 3 months of age.

Features of Hib infection in Russia

Unlike Western countries, where the main form of Hib infection is meningitis, in Russia, as well as other countries that do not routinely vaccinate against Hib, the most common form is acute respiratory diseases, including acute respiratory infections, pneumonia (pneumonia) and bronchitis.

In Russian studies in children's groups with a high frequency of colds, a high percentage of Hib carriage was identified. Vaccination in such groups has made it possible to significantly reduce the incidence of acute respiratory infections among frequently ill children.

In fact, high level Carriage of Hib explains the fact of frequent colds in children who begin to attend children's groups. This is why vaccination against Hib infection is required for all children before attending nursery or kindergarten.

Groups and risk factors

The factors on the basis of which risk groups for Hib infection are identified, and, accordingly, groups for priority vaccination, are:

• Artificial feeding - among such children an increased incidence is recorded, which is associated with the lack of substitutes mother's milk additional factors of protection against hemophilus influenzae infection.
• Visiting preschool institutions (nurseries, kindergartens, etc.). Vaccination is required for all children attending or planning to attend nurseries and kindergartens.
• Presence of school-aged children in the family - children over 5 years of age can be carriers and sources of CHIB for their younger brothers and sisters, however, they are less susceptible to infection due to their more complete development immune system.
• The presence of chronic diseases (immunodeficiencies and immunodeficiency states, frequent acute respiratory infections, heart and lung diseases, blood diseases, diabetes etc.) - the immune system of even completely healthy children is not able to adequately fight Haemophilus influenzae infection, and children with compromised immunity are even less ready to resist Hib.

Vaccination against Hib infection is also indicated for certain categories of children over 5 years of age and adults. Thus, in particular, in the USA it is recommended to vaccinate previously unvaccinated patients with sickle cell anemia, asplenia, patients with immunodeficiencies (in particular, those caused by AIDS, IgG2 deficiency), and patients with immunosuppression after chemotherapy.

A Brief History of Hib Vaccines

The first vaccine based on pure Hib capsule polysaccharide (PRP) appeared in 1985. It allowed partial protection for children only from the age of 18 months. and, since its main antigen remained defective, i.e., T-lymphocytes were never activated, revaccination with this vaccine did not lead to increased immunity.

It was first used then new way creating vaccines based on defective antigens - chemical compound(conjugation) of such substances with proteins, which made them full-fledged antigens. The first such vaccine, based on PRP and diphtheria toxoid (PRP-D), appeared in 1987. However, it did not provide adequate protection in children under 1.5 years of age. Other combinations were created - based on a modified diphtheria toxoid, one of the proteins of meningococcus, but they all had drawbacks.

Optimal results were achieved using a combination of PRP and tetanus toxoid (PRP-T), developed by researchers at the French company Sanofi Pasteur (formerly Aventis Pasteur). It was the PRP-T vaccine (Act-HIB) that made it possible to create reliable immunity by the age of 6-12 months, when the highest incidence of Hib meningitis is observed.

The creation of conjugate Hib vaccines made it possible to combine them with the main DPT vaccines for the vaccination schedule, which are also administered in fractions, using the revaccination effect. Combination vaccines based on a combination of DTP and Hib appeared and became firmly established in the vaccination calendars of Western countries. The first such multicomponent vaccine, PentAct-HIB (DTP+IPV+HIB), produced by Aventis Pasteur, was awarded the European Galen Prize in 1992 for its contribution to the development of pharmacology.

A Brief History of Hib Vaccination

Since 1989, with the advent of effective conjugate vaccines, vaccinations against Hib have been administered throughout the world. In 1989, mass vaccination began in Finland and Iceland, in 1990 in the USA, and since 1992 in Great Britain, Denmark and Norway. Studies have shown that with the help of routine vaccination over a period of 3 years, it was possible to reduce the incidence of Hib disease to isolated cases, which served to further spread vaccinations against Hib disease. Currently, vaccination against Hib is included in the vaccination calendars of all developed countries of the world.

Vaccination against Hib is recommended by the World Health Organization. It is expected that in the near future the WHO will introduce vaccinations against Hib into the recommended minimum vaccination schedule for developing and even backward countries of the world, where the need for this vaccine will be met by humanitarian organizations, including UNICEF.

In Russia, vaccination against Hib has been permitted and recommended by the Russian Ministry of Health since 1997. In a number of regions (Moscow, Moscow region, Krasnoyarsk, Irkutsk, Samara region, etc.) various programs are being conducted to prevent CHIB in risk groups. In the Tyumen region, for the first time in Russia, a program of routine vaccination of all children against Hib was adopted.

How Hib vaccines work

Conjugation of the main Hib antigen with a protein molecule made it possible to use the so-called. booster effect. In other words, Hib vaccines have a revaccination effect, when repeated administration of the vaccine causes not just a linear increase in the concentration of antibodies, but an increase in their concentration in geometric progression.

The peculiarity of the booster effect is that up to a certain stage, with each repeated administration, the increase in the number of antibodies also increases. This explains why the primary vaccination course consists of several vaccinations, and subsequent booster vaccinations are always carried out with just one dose of the vaccine. This, in particular, is the basis for the basic scheme for the use of Hib vaccines, when 3 vaccinations are given as part of the primary course, followed by a single revaccination.

Hib vaccines

The only vaccine with experience of mass use in Russia is Act-HIB produced by Sanofi Pasteur (France). It should be noted that Act-HIB is the original PRP-T vaccine, which made it possible to achieve major successes in eliminating Hib infection in developed countries of the world.

The Belgian Hib vaccine Hiberix, which is widespread in European countries, is also registered in Russia, but so far it does not have such large-scale Russian experience of use. A domestic vaccine against Hib infection is also in the process of development and registration.

Vaccination schedules against Hib infection

There are three regimens for the use of Hib vaccine, depending on the age at which the course of vaccination begins.

Classic scheme
When vaccination against hemophilus influenzae infection begins at 3 months, the vaccination schedule consists of four injections at the same ages when vaccinations with DPT vaccine are given - primary vaccination at 3 months, 4.5 months, 6 months plus revaccination at 18 months.

If a child is vaccinated according to an individual schedule or there are slight deviations from the calendar dates, then it should be remembered that the primary course of Hib vaccine consists of 3 vaccinations with a minimum interval of 1 month. Protective antibody concentrations using this regimen are guaranteed to be achieved 2 weeks after the 3rd vaccination.

The advantage of the classical regimen is that it allows the development of antibodies before the onset of the most dangerous age in terms of Hib meningitis (in addition to other forms of infection) - 6-12 months.

Alternative schemes
The older the child, the higher the ability of his immune system to independently form immunity to Hib infection.

When vaccination begins at 6 months, the course of vaccinations consists of two injections with an interval of 1-2 months. and the third injection of the vaccine, revaccination at the age of 18 months, and if vaccination begins at the age of 1-5 years, then the course of vaccinations consists of a single vaccination.

Alternative vaccination regimens are convenient in terms of preparation for entering a nursery or kindergarten, but their common disadvantage is the inability to protect the child until the most dangerous age in terms of severe forms of infection (meningitis, pneumonia) of 6-12 months.

Features of the use of Hib vaccines

The convenience of vaccines against Haemophilus influenzae infection lies not only in the coincidence of the basic scheme of their use with the scheme of administration of DTP vaccines. In addition, Hib vaccines can be combined in one syringe with DPT vaccines, reducing the number of injections and doctor visits while increasing protection components.

So, in particular, abroad and in Russia it is possible to combine the French vaccines “Tetrakok” and “Act-HIB” in one syringe; this is permitted by the instructions for both vaccines. A similar combination called “PentAct-HIB” is still widely used in France - the only difference is that the vaccine is supplied in a special two-chamber syringe, the components in which (HIB and DTP vaccine) are mixed directly during the administration of the drug.

Currently, multicomponent DTaP vaccines based on an acellular pertussis component are becoming increasingly popular in the West, in particular Pentaxim and Hexavak, consisting of 5 and 6 components, respectively. These vaccines, in addition to DTaP, polio and hepatitis B vaccines, also include a vaccine against Haemophilus influenzae.

Contraindications

There is only one specific contraindication, that is, characteristic of the Hib vaccine - an allergy to tetanus toxoid. In other words, an allergy to the tetanus vaccine, which is a component of, in particular, the DTP, ADS-M, AS and ADS vaccines.

This is explained by the fact that the main antigen of the vaccine against Haemophilus influenzae is chemically combined with a tetanus toxoid molecule. Although the Hib vaccine does not provide immunity to tetanus, people who are allergic to the tetanus vaccine may also have an allergic reaction to the Hib vaccine.

The remaining contraindications are common to all vaccines - the absence of acute diseases or exacerbations of chronic diseases at the time of vaccination; inadequate reactions to previous administration of Hib vaccine.

Adverse reactions to Hib vaccine

The Hib vaccine is easily tolerated. Reactions at the injection site (redness, thickening) are observed in no more than 5-7% of vaccinated people. Temperature reactions are rare and occur in 1% of vaccinated people. These reactions do not affect the usual lifestyle, do not require treatment and resolve spontaneously within 1-2 days.

Good tolerability allows you to combine and combine Hib vaccines with other vaccines in the vaccination schedule and, in particular, with DPT vaccines. Reactions and risks of adverse reactions to less reactogenic vaccines are absorbed by reactions to more “severe” ones, which is confirmed by practice - for example, the frequency of adverse reactions with the separate administration of the Tetracok vaccine (DTP + IPV) is actually no different from that when it is combined in one syringe with Act-HIB vaccine. Moreover, combining vaccines on the same day (or in the same syringe, if appropriate) minimizes the number of immune system activations, which further reduces the risk of side effects.

Efficacy and effects of vaccination

Current Hib vaccines are very effective. The incidence of all forms of infection in developed countries where routine immunization is carried out has decreased by 8598%. This can be achieved both through individual protection of the vaccinated and through the effect of collective protection, which is explained by the interruption of the chain of transmission of the bacterium by the immunity of the vaccinated.

In one of the Russian studies conducted in closed children's groups in the Moscow region, vaccination over the course of a year made it possible to reduce the level of carriage of Haemophilus influenzae from 41% to 3%, reducing the incidence of all colds(acute respiratory infections, bronchitis, pneumonia, etc.) several times. Similar effects and effectiveness were demonstrated in a study conducted on the results of vaccination in the Krasnoyarsk region.

Perspective

Main direction further development immunization against Hib is a combination of this vaccine with new generation DTP vaccines. Similar 4-, 5- and 6-component drugs have been used in Western countries for several years now.

It is expected that in the foreseeable future such vaccines will be registered in Russia. The first drugs of this class are already used in a number of CIS countries - in Ukraine, Georgia, etc.

As a more distant prospect, we can consider combining Hib vaccines with new conjugate vaccines against pneumococcal and meningococcal infections, which will allow for comprehensive prevention of diseases caused by these pathogens - acute respiratory infections, meningitis, pneumonia, otitis, etc.

New recommendations are under evaluation to change the administration of Hib vaccines, reducing the number of vaccinations within their basic regimen. In particular, a transition from a 4 to a 3-dose vaccination regimen is being discussed, which would reduce the cost of preventing Hib infection. However, these developments are still at a stage where it would be premature to make a forecast regarding their prospects.

There is reason to believe that in the near future, vaccination against Hib will be introduced into routine vaccination calendars in the CIS countries. This vaccination is already recommended by health authorities in Russia and Ukraine. In some countries, vaccination is carried out through international and foreign humanitarian organizations. According to the target program of the Ministry of Health, routine vaccinations against Hib infection may appear in the Russian calendar as early as 2007 or a little later, as the domestic vaccine is ready.

The widespread practice of immunizing children against Hib infection began in the mid-80s; since 1990, Hib vaccination has been introduced into the vaccination schedule in the USA, Canada and some countries Western Europe. Subsequently, in these countries, children began to suffer from epiglottitis, and other very rare diseases, much less often. dangerous diseases caused by Hib infection. Today, Hib vaccination is administered to young children in many countries around the world. In Russia, children from risk groups are vaccinated at state expense; parents can get all other children vaccinated for a fee at any medical institution that provides such services.

What is Hib?

The abbreviation HBI is the name of the microorganism Hemophilus influenza type B (Haemophilus influenzae type B). All diseases caused by this pathogen are combined into one group, which I classify as hemophilus influenzae infection.

Haemophilus influenzae type B has a number of features that allow it from the site of primary localization (usually respiratory tract) penetrate the blood and spread throughout the body, provoking the formation of purulent foci in various organs - the brain, lungs, joints, ears, etc.

Most common clinical manifestations hemophilus influenzae infection are the following acute diseases:

• Purulent.
• Epiglottitis (inflammation of the epiglottis), which leads to the development of croup.
• – inflammation of subcutaneous fatty tissue.
• Sepsis is a general inflammatory reaction of the body that occurs in response to pathogenic bacteria entering the bloodstream.

All these diseases develop mainly in those children who do not have immunity to Hib. Children in the first two years of life are especially susceptible to severe forms of hemophilus influenzae infection. Only timely vaccination (started at 3 months of age) can protect them. It, of course, does not provide an absolute guarantee: children who have received the vaccine also become infected with Haemophilus influenzae and get sick, but their illness progresses as usual or is practically asymptomatic.

A child can encounter Hib infection anywhere (the pathogen enters the human body from the air - via airborne droplets). Many people have been carriers and distributors of dangerous Haemophilus influenzae for years, but do not even know it.

Important:Children's groups are especially dangerous from the point of view of contracting hemophilus influenzae infection, so parents, when sending their child to kindergarten, must necessarily vaccinate him against Hib.

Indications for Hib vaccination

All children under 5 years of age must be vaccinated with Hib. Older children, as a rule, already have immunity to hemophilus influenzae infection (since they encountered it at least once in kindergarten or school), so severe forms of the disease are not dangerous for them. This is confirmed by long-term observations of Hib infection: among children over 5 years of age and adults, meningitis, pneumonia, and epiglottitis caused by Haemophilus influenzae are extremely rare.

However, some groups of children are vaccinated with Hib regardless of age, one can say vital signs. If they become infected with Haemophilus influenzae, they have the highest risk of developing the most severe forms of infection - meningitis, pneumonia, sepsis. Risk groups include children with:

• immunodeficiencies;
• oncological diseases;
• serious developmental defects;
• long history of use of immunosuppressants;
• (this also includes babies born to HIV-infected mothers);
• asplenia (absence or absolute dysfunction of the spleen).

In addition, in Russia, children in orphanages are subject to mandatory vaccination against Hib infection.

Contraindications to Hib vaccination

An absolute contraindication to Hib vaccination is the vaccine or its individual components. This fact is determined by the body’s abnormal reaction to the previous vaccination.

A child may be temporarily exempted from vaccination if, at the time of examination, he or she is diagnosed with acute illness or exacerbation chronic illness. Such children can be vaccinated with Hib a few weeks after recovery or improvement of their condition. If the illness was not severe (for example, intestinal disorders), vaccination is carried out immediately after normalization of body temperature, stool, etc.

To avoid any misunderstandings or undetected diseases that are contraindications to the vaccine, the child must be examined by a doctor before each vaccination.

Hib vaccination schedule

The Hib vaccination schedule is determined by the age at which this vaccination begins:

• If the child 3 months, then the Hib vaccination is done together with (combined drugs are often used for this, for example, Pentaxim). The next vaccinations are carried out at 4.5 and 6 months, and revaccination at 18 months. The schedule may shift if, for example, the first vaccination is given not at 3, but at 4 months, but in general, for children under 6 months of age, the principle of immunization against Hib infection should be as follows.
• If vaccination is necessary for a child who it's already been 6 months, but not yet a year old, the following schedule is used: 2 vaccinations are carried out at an interval of a month and revaccination a year after the second vaccination.
• For kids from 1 year to 5 years Those who have not previously been vaccinated against Hib are given a single immunization.

Thus, you should not be upset if for some reason the vaccination had to be postponed. The pediatrician will always be able to choose the most suitable and effective scheme vaccinations depending on the age of the small patient.

Preparing for Hib vaccination

No special preparation required. Parents only need to follow the general recommendations:

• Make sure that the child does not come into contact with contagious patients, stay less in closed crowded rooms, etc.
• Do not make sudden changes in your baby's diet.
• Monitor the child's stool (if there is a tendency to, take measures for normal bowel movements).

Side effects of Hib

Hib vaccination is easily tolerated by children. In 10% of cases, the following post-vaccination reactions are possible (develop at the site of vaccine administration):

• redness;
• compaction;
• soreness.

An increase in temperature (up to 38 degrees) is less common. Irritability, tearfulness, and poor appetite may also appear. If Hib vaccination was carried out complex preparation(together with DPT), the reaction to the vaccine may be more pronounced, but this is due not so much to the Hib component as to the DPT.

In general, those rare and minimal consequences of Hib vaccination are completely disproportionate in terms of the risk to the life of a child with ailments caused by Hemophilus influenzae. It’s better to bring down the temperature once and endure his whims with your baby than to face such a terrible disease as meningitis or sepsis.
