Dear Doctors, I keep on having the flu and Pharyngitis mainly in cold time of the year and during weather change. Is there any way that I can enhance my immunity system & prevent frequent illness?

The best way to avoid getting the flu is to get the influenza vaccine. You should get the vaccine as soon as it becomes available each fall, but you can also get it any time throughout the flu season (into December, January and beyond).
The vaccines work by exposing your immune system to the flu virus. Your body will build up antibodies to the virus to protect you from getting the flu. You cannot get the flu from the flu vaccine.

You can also reduce your risk of catching the flu by washing your hands frequently, which stops the spread of germs. Eating healthy, exercising and getting enough sleep also play a part in preventing the flu because they help boost your immune system.
