The best protection: vaccination
The best way to protect yourself against the influenza virus remains vaccination. The latter protects against the disease in least 70% of healthy persons and reduces the symptoms in others.
How the vaccine operates?
The influenza virus vaccine is composed of inactivated virus particles and does not cause influenza, unlike what many people believe. The composition of the vaccine varies each year according to, in particular, observations from the Global Laboratory Network, coordinated by the World Health Organization. The function of this network is to isolate the viruses everywhere in the world and to identify new influenza strains. We then must be vaccinated each year.
