Can people with MS get vaccinations?
Once there was concern that vaccinations might increase the activity of the immune system leading to MS attacks. This does not seem to be the case. Studies have not found any increase in MS attacks following flu and hepatitis vaccines. Since most other vaccines are given in childhood, and MS affects mostly adults, there have not been sufficient studies of other vaccines to find out if they are a problem for people with MS. However, it is known that the flu, pneumonia and other infections may cause MS attacks from time to time. The risk of attacks from the infection is believed to be higher than the risk from the vaccine. It is therefore recommended that people with MS get vaccinated for diseases to which they may be exposed.
