Entry to Spain - vaccination certificate to expire after 270 days
I don't know if you are aware of a new EU regulation.
From 1st of February COVID-19 Vaccination Certificates are valid for only 9 months (270 days) from last jab.
There are plenty of stupid advices in media to obtain a booster jab if your double jabs are expired... but nobody continues the advice to say - what when booster jab is expired? (as every other jab it works only for certain period). There is no 4th dose in the UK.
It looks like those who had their booster in for example November last year won't be able to enter Spain (EU countries are free to follow the regulation, Spain will do) from August (when 270 days are gone) etc.
