Quote:Most people with relapsing and progressive forms of multiple sclerosis (MS) should get a COVID-19 vaccine, the National Multiple Sclerosis Society advised.
The new guidance, issued January 13, is similar to ones issued by the MS International Federation and other organizations and refers to mRNA vaccines by Pfizer/BioNTech and Moderna only.
"The risks of COVID-19 disease outweigh any potential risks from the vaccine," National MS Society experts wrote. "In addition, members of the same household and close contacts should also get a COVID-19 vaccine when available to decrease the impact of the virus."
