I'm looking for some clarification on the covid vaccine and booster requirements for US travelers entering Spain. The entry requirements for Spain state that a covid-19 test upon arrival is not required for fully vaccinated travelers who have 'documentation showing proof of a final dose of an accepted vaccine (essentially Moderna or Pfizer) at least 14 days and at most 270 days before arrival, **or a booster is required.'** I am a fully vaccinated and boosted traveler who got two doses of Moderna vaccine in March and April 2021 and booster shot in November 2021. It is unclear to me if the 14-270 day range is applicable to the two doses of the original vaccine shots or also to the booster shot? One interpretation of the Spain entry requirements is that if you have the two doses of the vaccine at least 14 days and at most 270 days you can enter Spain without testing, and if your original two vaccine shots are more than 270 days out you can have a booster at any time (no time expiration requirements) and still be admitted to Spain without testing.
However, the stricter interpretation of the entry requirements is that the 14 days to 270 days is applicable to both the original two vaccine shots and the booster, so if your booster was more than 270 days from date of arrival, you would be required to provide a negative covid test before entry to Spain. I am under 50 years old and not immunocompromised, so I am not eligible for a second booster shot at this time. Have any fellow travelers been to Spain in the past few months and would you be able to help me interpret the entry requirements in terms of whether the 14 to 270 day range is applicable for the original vaccine shots only and if you have a booster at any time will that be acceptable as proof of full vaccination without the need to present a negative covid test upon entry?
I would appreciate anyone's thoughts or experiences with this topic.
