Is it worth getting a flu shot if I've already had it this season?

Yes, it is worth getting vaccinated, even if you have already had the flu this season. Although your body has naturally already come into contact with the virus during infection, it is important to remember that influenza can be caused by several types of flu virus and having one infection does not prevent infection with another type. The vaccine, on the other hand, contains antigens from several different influenza viruses. The flu epidemic season in Poland lasts from October to May, so it is worth considering vaccination. As for the autumn season, it is advisable to re-vaccinate. Every year, a new antigenic composition of the vaccine is developed, which is based on the types of influenza virus that caused the most common infections in the previous season. Therefore, a single vaccination does not immunize for life, and annual vaccination is advisable.
