The flu shot is an annual vaccination that protects you against the influenza virus, better known as the flu. The flu can cause a bad cold with fever, coughing, muscle aches and fatigue. Especially if you have reduced immunity, are older or chronically ill, you can become more seriously ill with the flu. The flu shot is given in GP practices between mid-October and the end of November.
The flu shot contains small pieces of different types of dead flu viruses. These bits are harmless. They make your body produce antibodies against the flu virus. About 2 weeks after the flu shot, you have enough antibodies. Does the flu virus enter your body after these 2 weeks? Then the antibodies can render the flu virus harmless. So the antibodies ensure that you do not get sick from the virus, or get less sick.
The flu shot only protects you against the most common flu viruses. So you are not protected against other viruses, such as the virus that gives colds or the corona virus.
The flu virus changes regularly, which is why it is important to get a new flu shot every year so that your body can produce new antibodies each time. Getting vaccinated also reduces your chances of getting the flu and prevents you from passing on the virus to vulnerable people around you.
You can get the flu shot and corona shot shortly after each other. There does not have to be any time in between.

Serious side effects of the flu shot are not common.
