The European Medicines Agency has approved the Pfizer-BioNTech Covid-19 vaccine for use in 12 to 15-year olds on Friday.
It will be the first Covid vaccine available for adolescents.
Until now, the vaccine has been approved for use in the EU in those aged 16 and over, but the regulator announced earlier this month that it had begun evaluating evidence of its safety and efficacy in younger groups.
The vaccine has already been approved for emergency use in the 12-15 age group in the United States, with the Food and Drug Administration announcing on May 10th that trial data showed the benefits of the vaccine outweighed known and potential risks.
