Checking requirements to fly to various countries esp. in the EU

From doing as much due diligence as possible it seems that with an EU Covid Vaccine Cert and there having passed 14 days since the 2nd Vaccination, you can travel to and from the Czech republic without requiring any other forms of test with the exception of having to fill in a Passenger locator form. It's not the easiest of data to find especially with regard to the non Irish portion, returning to Ireland is pretty well covered on the DFA Website. It is worth noting I was issued my Cert before 14 days since my 2nd injection had been administered, so people could potentially be caught out by that, some countries require only 7 day, Czech 14 etc. etc.
