Introduction: Flu vaccine side effect. Influenza, commonly known as the flu, is a contagious respiratory illness from influenza viruses. Vaccination is one of the most effective ways to prevent the flu and its difficulties. Flu vaccines stimulate the immune system to produce an immune response against the virus, which protects during flu season.
Like all medications, the flu vaccine can cause side effects. They are usually mild and usually last only a day or two. It is expected to experience side effects after vaccination. This shows that the vaccine teaches your body’s immune system to protect itself from the disease. But not everyone has side effects.
The best and most effective way to prevent the flu and its spread is to get vaccinated. The flu vaccine is available as an injection shot. The more individuals immunized against the flu, the less the flu can spread. The vaccine, which usually comes as a shot but also as a nasal spray, can reduce your chances of getting the flu by up to 60 percent.
