Flu Shots for MS Patients

November 21, 2017

It is that time of the year again when many patients will begin wondering whether or not to get a flu shot. Here are the opinions of a few doctors from a U.S. News and World Report article that’s specifically about MS and the flu:

Dr. Robert Shin, director of the Georgetown Multiple Sclerosis and Neuroimmunology Center: “The flu infection may stimulate the immune system, which may in turn trigger an MS attack.” Shin says that getting the flu, or any illness, raises that chance that you’ll have a relapse or a worsening of your symptoms.

Dr. Amesh Adalja, an infectious disease specialist with the Johns Hopkins University Center for Health Security: “When you see flu outbreaks, you see MS relapses.”

If you just think about what happens to your body in hot weather, or when you have a fever, then the flu-MS connection should be clear. The flu shot doesn’t give you the flu.

Are you worried that getting a flu shot can give you the flu, or make you sick with something else? Doctors say don’t be. The flu shot uses a killed virus to protect you against the flu. So it’s highly unlikely that the vaccine will give you the flu. In fact, Dr. Shin says “infection really is impossible.”

On the other hand, the nasal flu vaccine is created from a live virus. The Centers for Disease Control and Prevention recommends against anyone using the nasal vaccine, because there are concerns about its effectiveness.

Since the flu vaccine takes about two weeks to become fully effective, it’s possible that some people who’ve had a shot will still get the flu. There have also been some years where the vaccine hasn’t been a good match for the strain of flu that was prevalent in those years. This may lead some people to believe that the shot gave them the flu when, in fact, it didn’t. It just, for whatever reason, failed to protect them from catching it.
