I read that you only need proof of vaccination for entry.No testing or health insurance required at this time.Is this accurate?
That's what I've read on the US Embassy to Turkey's website, and my airline sites and on Sherpa. Proof of vaccination at least 14 days prior.
ETA: my research was for a US passport.
Having said that, I'm still scheduled for a PCR test because of reports of people being asked for them to go to countries that do not require them. Better safe, for me, than no vacation.
You'll also want to check your airline and any countries through which you transit. Some have requirements even if you do not enter the country, but just pass through from one flight to the next.
I agree with CWSocial
