If you are resident in Spain and are considering visiting relatives or friends outside Spain from today, December 1, you will need a certificate of your Covid-19 vaccinations to re-enter Spain.
If you do not have a vaccination certificate you will require a negative antigen test or a recovery certificate.
If you are not an EU citizen or a resident of Spain, but fall within the exempt category because of the urgency of your visit (check UK gov site for details of exemptions) you require a certificate of your vaccination, a negative antigen test, or a recovery certificate.
If you do not fall within the exempt category (tourist or routine family visit) you will need a vaccination certificate to enter Spain.
Editors Note:
If you fall into the age or other categories for the Covid booster you will need to have your booster and download an updated certificate.
