It was announced on Saturday, September 3, that the UK's Medicines and Healthcare Products Regulatory Agency (MHRA) has approved a second Covid-19 booster vaccine to target the Omicron variant.
The MHRA approved the first bivalent Covid booster vaccine in August 2022, making the UK the first country in the world to do so.
The approval for the second vaccine was made following a clinical trial, which showed that a booster dose with the bivalent vaccine triggers a strong immune response against Omicron and the original Covid-19 strain.
