The UK's medicines regulator has approved the Pfizer/BioNTech coronavirus vaccine for 12 to 15-year-olds.
The Medicines and Healthcare products Regulatory Agency (MHRA) said the decision followed a "rigorous review" of safety and effectiveness in that age group - and that the benefits of having the COVID jab outweighed the risks.
Dr June Raine, MHRA chief executive, said: "We have in place a comprehensive safety surveillance strategy for monitoring the safety of all UK-approved COVID-19 vaccines and this surveillance will include the 12- to 15-year age group."
