Can you get the flu even if have had vaccination?

Yes, it is possible to get the flu even if you have been vaccinated. However, the flu vaccine is very effective at preventing the flu, and it can significantly reduce your risk of getting sick.

The flu vaccine works by stimulating your immune system to produce antibodies against the flu virus. These antibodies can then help you fight off the infection if you are exposed to the virus. However, there are a few reasons why you might still get the flu even if you have been vaccinated.

* You may not have been vaccinated long enough before you were exposed to the virus. It takes about two weeks for the flu vaccine to provide full protection. If you were exposed to the virus before your body had time to produce antibodies, you could still get sick.

* You may have been exposed to a strain of the flu virus that is not covered by the vaccine. The flu vaccine is designed to protect against the most common strains of the flu virus, but new strains can emerge each year. If you were exposed to a new strain of the virus, you could still get sick even if you have been vaccinated.

* Your immune system may be weakened. Some people have a weakened immune system due to a medical condition or medication. If your immune system is weakened, you may be more likely to get the flu even if you have been vaccinated.

If you have any concerns about the flu vaccine, talk to your doctor.
