I'm headed to Germany in a couple weeks and am having a hard time determining if I am considered "fully vaccinated". I got the US 1-dose J&J/Janssen vaccine in April 2021 and got a Moderna booster in October 2021. So I have gotten "2 shots" and it's been less than 270 days since my second shot, but looking at what other folks are reporting for accepted vaccinations from airlines, I don't see mix-and-match vaccinations on the approved lists. Anyone have direct experience with this? Or have clearer evidence if I'm okay? Thanks!
