Vaccination does not increase the risk of developing multiple sclerosis

Takeaway

  • Vaccination does not appear to increase the risk of multiple sclerosis (MS); in fact, results show that vaccination is associated with a lower likelihood of being diagnosed with MS within the next 5 years.

Why this matters

    The role of vaccination as a risk factor for MS has been controversial; not only do these findings refute the theory that vaccinations are a risk factor for the development of MS, they suggest that vaccinating may provide protective effects.
