Which vaccine to get?

[davester]

I don't think it matters. Both Pfizer and Moderna are mRNA vaccines so they initiate essentially the same mechanism within your body to create immunity. The advantage of Pfizer is that they tested it with a 3-week period between shots whereas Moderna tested with 4 weeks. Since they are following the procedures used during testing, the Pfizer gets you a booster shot a week sooner. Whether this is good or bad is hard to say. From the data available, I'd guess that they both give the same level of immunity. J&J is one shot and you're done, so it has convenience on its side. It also is linked to extremely rare blood clotting. A pro and a con.

Bottom line...it doesn't matter what shot you get. The important thing is that you get one ASAP.
