"FYI.
There is accumulating sentiment and evidence in the medical community that there's some cross-reactivity between COVID-19 and the antibodies from MMR vaccine. Perhaps this is why kids do better than adults when they get COVID.
Therefore, it may be worth it for you to have another MMR even though you most likely were already immunized with MMR in the past. The reason for another vaccine shot now is to boost your immune response. MMR vaccine doesn't have any serious side effects.
I got my MMR today."
