LSHTM expert comment: UK's MHRA approves bivalent COVID-19 vaccine

The UK's Medicines and Healthcare products Regulatory Agency (MHRA) has approved a booster vaccine made by Moderna which targets two COVID-19 variants, known as a bivalent vaccine. Following clinical trial data that showed it triggers a strong immune response against both strains, the vaccine was found to meet the UK regulator's standards for safety, quality and effectiveness. Vaccine expert, Professor Beate Kampmann reacts to this announcement.
