I am travelling to Spain at the end of September from the US and I am having trouble finding specific information on getting the QR code. I can't enter any information until 72 hours prior to arriving.
For the vaccine document would a simple paper certificate for my booster work or does it need some additional information?
For a negative PCR test would a simple test from CVS or Walgreens work or do I need an official one that has my passport number on there as well?
Any advice from someone who has gone to Spain recently from the US would be much appreciated.
Thanks in advance!
