Influenza vaccines contain inactivated virus or a specific part of it. It is important to emphasize that a vaccine containing an inactivated virus does not cause disease, its only role is to put the immune system in a position to protect itself against the flu. In some cases, fever, headache, tiredness, weakness, discomfort, redness, swelling and mild pain at the site of the injection may occur after the vaccine has been given. These symptoms only temporarily cause unpleasantness. After a few days, they subside spontaneously and then they pass.
Vaccination is recommended over the age of six months. Protection against influenza develops in 2-3 weeks after vaccination.
Before requesting a vaccine, be sure to talk to your doctor about the possibility of vaccination (taking into account your medical history, whether you have ever had a severe allergic reaction after eating eggs, whether you needed medical intervention after a previous vaccination).
