There is discussion on weather vaccination is a risk factor for MS or not. A research team from Munich reported that vaccination was not a risk factor for MS. On the contrary, they consistently suggested that vaccination be associated with a lower likelihood of being diagnosed with MS within the next 5 years(Hapfelmeier et al. 2019) .
