If you would like to get the flu shot because you are afraid that the flu could worsen your long-term symptoms, you can discuss this with your GP. Often, if there are sufficient vaccines available at your GP or pharmacy, you can get a flu shot at your own request. This will incur costs for you. A flu shot only helps against getting sick from the influenza virus. There are also many other cold viruses in circulation. The flu shot does not protect against these.
