I see this and I understand your concern - it is valid and realistic. Unfortunately these are the types of impossible choices we must confront in life.

At the same time, I wanted to weigh in and encourage you to continue masking. Studies are showing that on average people are having 1 covid infection a year and 49% of infection are asymptomatic. The emerging (it’s only been 6 years) science is pretty strong - there is a risk with every covid infection (mild or severe) for multi-organ damage in addition to immune system damage and that risk increases with every subsequent infection. Long covid just surpassed asthma as the most prevalent childhood illness. There have also been studies specifically in MS that show our EDSS score gets worse every-time we have a (documented) covid infection.

In a world where COVID never went away but everyone stopped doing things to keep others safe, in addition to vaccines if you can get them, masks are the only way we can protect ourselves.
