A full course of immunization (administration of two doses of Algavac M vaccine with an interval of 6–12 months) activates additional production of antibodies in high titers, which ensures the development of long-term specific immunity to the hepatitis A virus in 90–100% of vaccinated people.
Indications for use

- persons who have contact in the foci of hepatitis A;
- persons traveling (travelers, military personnel, etc.) or living in regions with a high incidence of hepatitis A;
- persons from special risk groups: patients with an increased risk of liver disease, chronic liver disease, hemophilia or multiple blood transfusions, people with promiscuous sex life, homosexuals, drug addicts;
- persons at risk of occupational infection: medical workers, nursing staff (especially in pediatric, infectious and gastroenterological departments), employees of preschool institutions, staff of catering and food industries, workers in water supply and sewage services.
Contraindications
- malignant blood diseases and neoplasms;
- immunodeficiency states;
- a pronounced reaction with the previous administration of the drug (an increase in body temperature above 40 ° C, hyperemia and edema at the site of inoculation more than 8 cm in diameter);
- children under 3 years old;
- hypersensitivity to any component of Algavac M.
Temporary contraindications to the Algavac M vaccination are acute infectious and non-infectious diseases or exacerbation of chronic diseases.

Vaccination during pregnancy and lactation is possible if the expected benefits are higher than the potential risks.

Algavac M is injected intramuscularly into the deltoid muscle of the shoulder.
Intravenous administration of the drug is prohibited! It is not recommended to inject the vaccine subcutaneously, intradermally or intramuscularly into the gluteal region, as this leads to the formation of a lower immune response.
One vaccination dose is 0.5 ml for children and adolescents up to 17 years old, 1 ml - for adults over 18 years old. Long-term protection against hepatitis A is provided by a course of two vaccinations, given 6–12 months apart. In exceptional cases, revaccination is allowed at a later date after the first dose.
The opening of the ampoules and the introduction of the Algavac M vaccine is carried out by a medical worker, strictly observing the rules of antiseptics and asepsis.
