Covid, UK green light for Moderna bivalent vaccine that also counteracts Omicron

Bivalent vaccine against Covid: the country is the first to approve Moderna’s drug which tackles both the original Wuhan strain and the first variant of Omicron and will be part of the autumn booster campaign

The UK is the first country to approve Moderna’s new bivalent vaccine

The vaccine addresses both the original strain of Covid-19 (the one that emerged in Wuhan in 2019) and the first variant of Omicron (BA.1).

The vaccine will now be part of the autumn booster campaign.

Moderna will try to make 13 million doses of the new vaccine available, but 26 million people could benefit from a booster dose.

Experiments on 437 people showed that the updated, bivalent vaccine is safe and offers better immune protection against the new variants

“Levels of antibodies capable of attaching to and disabling Omicron (BA.1) were 1.7 times higher in people given the new vaccine.

Tests against the newer variants of Omicron (BA.4 and BA.5), which caused the latest wave of infections in the UK, also showed higher levels of protection with the updated vaccine,’ reads the BBC.


The UK’s Joint Committee on Vaccination and Immunisation (Jcvi) has confirmed that some form of booster should be offered in the autumn to the following groups of people: health and social care staff; the over-50s; carers over the age of 16; frail people over the age of five, including pregnant women; and people over the age of five who share a household with someone with a weakened immune system.

Moderna, the BBC reports, is not the only company upgrading its vaccines.

Pfizer has also developed vaccines that can target Omicron.

The Oxford-AstraZeneca vaccine, on the other hand, is not being updated.
