Vaccination
A vaccine against the swine flu virus has been available since 2009 and is now integrated into every seasonal flu vaccination. The vaccine is a so-called dead vaccine, which contains killed viruses that can no longer infect the organism. However, they are sufficient to stimulate the body’s own immune system to produce antibodies that prevent disease in case of infection with live viruses. Since the swine flu virus, like all influenza viruses, often develops mutations, the vaccine must be recomposed every year and one must be vaccinated every year in order to have sufficient protection for the season.
