Today was the first day that Spain allowed people from some countries who have been vaccinated to enter the without needing to enter on important business.
The Spanish consulate website said you need two things to enter the country now. First, proof of vaccination. Second, to complete a form on the website for health and travel published by the Spanish government. The form asks all the standard Covid related health questions (have you been in contact with some poor bastard dying of COVID?, etc.), asked if you were vaccinated and also if you had a negative Covid test in the 72 hours before arrival.
But when I actually entered the country, they didn’t ask to see proof of vaccination They only scanned the QR code on the app, then waved me in.
