Britain's health regulator approves Pfizer/BioNTech COVID vaccine for infants

Britain's health regulator on Tuesday authorised the use of a version of a COVID-19 vaccine made by Pfizer and BioNTech in infants and children aged 6 months to 4 years.

Whether the vaccine is eventually deployed in this age group depends on a recommendation from the UK's Joint Committee on Vaccination and Immunisation (JCVI), which advises on which shots are used as part of the national vaccination programme.

The endorsement from the Medicines and Healthcare products Regulatory Agency (MHRA) is based on data from an ongoing clinical trial involving 4,526 participants.
