On Monday the US biotech firm Moderna said it had completed regulatory submissions for its updated Covid vaccine in the UK, Europe and Australia. If approved by the UK Medicines and Healthcare products Regulatory Agency (MHRA), the bivalent vaccine, which primes the immune system against Omicron and the original strain of Covid virus, will be available for the autumn booster programme.
In a press statement, Moderna said the updated booster outperformed its existing booster against the now-dominant BA.4 and BA.4 variants of Omicron, raising neutralising antibody levels 70% higher.
In the autumn, people aged 65 and over in the UK will be offered a booster, as will frontline health and social care workers, and there is a suggestion everyone over 50 may be included in the programme.
