Fluvirin is a vaccine used to prevent seasonal influenza. It contains inactivated viruses that stimulate the immune system to produce antibodies that provide protection against the strains circulating in a given season. Fluverine helps reduce the risk of influenza infection or alleviate its symptoms if they occur, especially in groups most at risk of complications, such as the elderly, children, and people with chronic diseases.
The Fluvirin vaccine is given by intramuscular injection and begins to take effect approximately two weeks after vaccination. Therefore, it is recommended to receive it before the start of the flu season to ensure maximum benefit. The vaccine is generally safe, with the possibility of mild side effects, such as redness or swelling at the injection site or a slight increase in temperature. These symptoms subside within a short period.
