I can get mine any time after the 17th. I’ve only had Pfizer so far, going to see if I can get Moderna this time. I’ve been trying to figure out if I should be getting the booster dose or the full dose if I go the Moderna route. Spring semester begins in the 17th so the sooner I get that 4th dose the better I will feel about going back to work!
Per that link, if you are immunocompromised, you should get three FULL doses, and then 5 weeks after your third full dose, you will get the BOOSTER, which is HALF. So, our series is 3 primary shots, followed by a booster, whereas normal people are 2 primary shots, followed by a booster.
When I signed up for my appointment at a chain pharmacy, it asked me if I wanted a third dose as an immunocompromised person or if I wanted a booster -- I selected booster.
Going on Tuesday!
