With a number of places requiring that you need your final primary covid vaccine or booster within 270 days of travel what happens if your booster is more than 270 days old before summer?
I had my booster in Oct due to work so the 270 days is up early June. Will I need another booster to be allowed entry in Europe? I can’t find definitive advice anywhere about whether countries consider that the booster “runs out” like the primary course. Or whether you can get a further booster.
If anyone has any links to advice I’d appreciate it!
