Britain approves Pfizer/BioNTech's updated Covid-19 booster vaccine

Britain's medicines regulator on Saturday approved Pfizer/BioNTech's updated bivalent Covid-19 booster shot for people aged 12 years and older, Reuters.

The Medicines and Healthcare products Regulatory Agency said the decision was based on data from a clinical trial that showed a booster dose with the bivalent Pfizer/BioNTech vaccine triggers a strong immune response against both the omicron and the original strain.
