Adverse reactions during scheduled vaccinations are now quite rare. Distinguish between general and local complications.

  • Local complications include reactions at the injection site — redness, suppuration, lymphadenitis;
  • Common complications, allergic reactions, fever, symptoms of infectious disease.

The most common causes of complications:

  • Failure to comply with contraindications;
  • Violation rules and techniques of vaccination;
  • Poor quality of the vaccine;
  • Violation transport and storage vaccine;
  • Individual reactions due to vaccination.

Complications associated with non-compliance of contraindications. This is the most serious complication, because they may threaten the life of the child. For example, congenital immunodeficiency, the child may die from the consequences of the introduction of live vaccines (measles, rubella, etc.).

Complications related to the violation of rules and techniques of vaccination. These complications arise when introduced is too large, or dose of the vaccine preparation was administered wrong way (e.g., subcutaneously, intracutaneously instead). Most often, this raises fester in the injection site. In the case of far-gone the process may be swollen lymph nodes (lymphadenitis). With the introduction of large doses of the drug may be allergic reactions.

Complications associated with poor quality vaccines. This kind of complications can be suspected if children vaccinated one series having the same type of vaccine complications. Over the past 25 years, no vaccine domestic production was not suspected in an improper security.

Complications related to the violation of the conditions of transportation and storage. Violation temperature during transportation and storage of some vaccines accompanied by a decrease of efficiency, changes in properties of the vaccine, which may lead to serious allergic reactions up to anaphylactic shock.

Complications associated with the individual hypersensitivity to the vaccine. This group represents the greatest risk of complications as to predict their possible development of a particular child is in most cases impossible. Often manifest as neurologic and allergic reactions.

Depending on the type of vaccine such complications can be caused by:

  • toxic effect of the drug itself (inactivated vaccine);
  • infectious process occurring after the administration of the vaccine (live vaccine);
  • the development of a perverted sensitivity to the drug (sensitization).

Treatment of complications

In case of complications after vaccination is an urgent need to see a doctor who prescribed medication (antipyretics, anti-allergy drugs, antibiotics, topical treatment, etc.).

In recent years, despite the dramatically increase the vaccination coverage in Moscow annually registered individual complications. In accordance with the Resolution of the Government of the Russian Federation of 27.12.2000 № 1013 all citizens in the event of post-vaccination complications paid compensation.
