Fernando Valdés, The Secretary of State for Tourism in Spain, said that the vaccination passport would be complementary to other measures, such as negative tests, masks and social distance, not a replacement.
With the European Union now accepting that vaccination passports will be a strategy for travel internally in the Union itself, excluding the UK because they are outside of the EU. This means European member countries need to negotiate directly with the UK on the regulations surrounding a vaccination passport.
One example currently is Greece, who have been negotiating the terms and have said on Thursday that they are ready to reopen in May and accept vaccinated British tourists, who have a vaccination certificate/passport without the need to have a negative PCR test.
Therefore Spain will have to negotiate directly with the UK government on the terms of use for a vaccination passport to "create a regime of measures that allow British tourists to visit their most popular destination this summer", according to TTG.
Valdés has said that vaccination passports and certificates will be among the measures that will allow the British to spend their holidays in Spain this summer. However, people who do not have a certificate will still be able to enter the country with a negative PCR test, as they will still be valid. "We feel that summer has to be the beginning of the gradual restoration of international tourism to Spain, and we hope to welcome British tourists again," Valdés said.
Almost all Spanish destinations would agree to the vaccination passport if the EU finally gives its approval. However, the Canary Islands look like they are choosing to insist on a negative test result for travellers from the UK, when trips resume, with the vaccination passport being just one more measure to prevent the spread of the virus.
