Spain has updated rules on booster vaccines for tourists from the UK aged 12 to 18.
To enter Spain without having to pay for and take a Covid-19 test, or show a proof of recovery, British nationals must be "fully vaccinated". But the definition of what fully vaccinated means differs between adults and teenagers.
The rules are more relaxed for holidaymakers aged 12 to 17 and should mean most teenagers will not require a booster to be considered fully vaccinated by Spanish border authorities. But they will need to have had at least two jabs, or one-shot if they received a single-jab vaccine.
