It doesn't look like the US will be issuing "vaccine passports," so is the CDC card signed by the pharmacy that performed the vaccination considered enough for Greece?
Proof of a negative test is not required however for all travelers that have completed their vaccination (i.e., 14 days have elapsed since the last vaccination, depending on the doses required) and hold a vaccination certificate.
Nowhere did I see a definition/description of what is a "vaccination certificate"
Presumably a Greek Embassy/Consulate can answer the question
Hi there, yes at the moment is enough. Keep in your mind that restrictions changed day by day though.
I arrived three days ago, and wasn’t asked to see any “certificate”. When I filled out the PLF online, it asked for the date of the second shot. (Interesting I was completing the PLF for my wife, granddaughter and me - but it never asked their last dates of their vaccination.) We brought along our cards that everyone received with the dates, the type (mine was Moderna), the batch #, etc. when we flew to Santorini the next day that was what was we showed and it was accepted.
This current thread might help:
@Springstein - Thank you for the information. Based on what I've seen it looks like the pharmacy-issued cards are enough to get into Greece. Actually now it looks like the real hassle is getting back into the US. The CDC is requiring negative Covid tests even if you have been vaccinated. Do you have a plan for this?
