A vaccine is needed to protect the body from disease and its consequences. Since immunity begins to develop on the second day after vaccination, it is recommended to do it a few days before the epidemic begins.
Vaccination to prevent influenza
Prevent the flu allows the drug "Influvac". The instructions for use state that the vaccine develops a form of immunity that opposes viruses of groups A and B. Immunity appears 2 weeks after complete immunization. Its validity period is 1 year.
For vaccination, non-live vaccines are chosen, for example, "Influvac" - a drug that contains surface particles of the influenza virus. They also form immunity in the patient. You can also give preference to a split vaccine, which contains virus cells in a destroyed form.
Each of these vaccines are completely safe andaction provide the same barrier to immunity. There is no live virus in any of the injections. The Influvac vaccine is guaranteed to protect against the flu. Instructions for use, reviews - this is additional evidence that the injection is effective and safe.
As a rule, domestic and imported vaccines differ in two ways:
- Cleaning the drug in two stages.
- Quality control.
Because of these benefits, Influvac vaccine does not cause side effects, so it can be given even to the youngest children at the age of 6 months, as well as people with chronic diseases, pregnant or breastfeeding women.

Instructions for use "Influvac" contains certain contraindications for vaccination, including:
- Illness at the stage of exacerbation or chronic form of the disease on the day of vaccination.

In addition, the vaccination of the patient is delayed if he has a mild form of a cold or an acute intestinal infection, as a result of which a high fever appears.
Adverse reaction to Influvac vaccine
Possible side effects after vaccination with the drug"Influvac". The instructions for use do not deny the development of complications in some cases, but this happens in a small number of vaccinated people. Medical data show that among adults, a general reaction occurred in only 1% of patients who were vaccinated, and 4% of the population had a local reaction. As for exacerbations or complications after injections, none have been reported.
The reaction to the vaccine can be local or general, each has its own symptoms. The general reaction is characterized by such signs as:
- Elevated body temperature for a while, no higher than 37.5.

- Slight redness of the injection site.
- Small size seal.
- Pain occurs in some cases.
- This reaction lasts a maximum of 2 days and does not cause much discomfort.
In any case, if there is an adverse reaction to the flu injection, this indicates that the immune system is working at full capacity. In some cases, anaphylactic shock may occur, so the injection room should have medicines to relieve it, such as adrenaline.
"Influvac" has no effect on the abilitydrive any vehicle, this also applies to other machines or mechanisms.
Adverse reaction from the body
In some cases, the influenza vaccine "Influvac" (instruction warns) causes complications from certain organs of the body.
Vaccination can damage the circulatory and lymphatic systems, resulting in low platelet counts and therefore a high risk of bleeding and bleeding problems.
On the part of the immune system, allergic reactions occur, and in some cases even anaphylactic shock.
Nervous system damage causes migraine, very rarely paralysis and convulsions, as well as encephalomyelitis or neuritis. But studies don't show a link between the vaccine and the reaction.
Disorders of the vascular system entail vasculitis, which is accompanied by transient changes in the functioning of the kidneys.
Assignment of the vaccine "Influvac". Instructions for use
Vaccination helps not only to protect the body, but also to carry out prevention, for example, in young children. In addition, people who are at high risk are vaccinated first. This population is over the age of 65, with diseases of the respiratory organs or heart, suffering from chronic renal failure, diabetics. Also included in this group are people who have weak immunity, who take drugs that depress his work, or who are undergoing medical therapy againstcancer who receives a high dose of corticosteroids.
Vaccination is carried out by children at school and adolescence up to 18 years of age, especially those who have taken medications containing acetylsalicylic acid for a long time. They are at risk of getting Reye's syndrome, which develops as an adverse reaction after an infectious flu.
As a rule, the vaccine is given to pregnant women in the 2nd or 3rd trimester, but if there is a high risk of infection, then the vaccination is carried out at any time with the medicine "Influvac". Instructions for use provide for such vaccination measures.
