Good information, @athenalee I'm post-transplant at Mass General and they too sent out some info and invited us to have a vaccination there. I was already registered here in NH but I decided to go to MGH and cancel my appointment here. Some states have run out of the vaccine and had to delay giving the second dose. I figured that would be less apt to happen at Mass General. I am due for my second shot on February 14th.

They are now following me with extra lab work. I had to go today, again next week, then one more time out of sync with my regular labs. Then I will return to my regular every other month schedule. It's a bit of a nuisance but I really like their diligence so I'm not unhappy about that.
