Moderna’s ‘next generation’ COVID booster gets approval in the UK

Moderna’s “next generation” COVID booster, which targets both the original and Omicron strains of the virus, has been cleared for use in adults in the UK

The dose can increase antibody levels to a point where it might only be needed annually, says Moderna’s chief medical officer.

The UK’s Medicines and Healthcare products Regulatory Agency (MHRA) authorized the booster on Monday.

“We are delighted with the MHRA’s authorization of Spikevax Bivalent Original/Omicron, our next-generation COVID-19 vaccine,” said Stéphane Bancel, CEO of modern in a statement. “This bivalent vaccine has an important role to play in protecting people in the UK from COVID-19 as we enter the winter months.”

The company says it expects further authorization decisions from other countries in the coming weeks.

Whether that will occur in the US, however, is a complicated matter. The Moderna booster that received approval in the UK, known as mRNA-1273.214, targets the BA.1 Omicron mutation, not BA.4 or BA.5, which the US Food and Drug Administration (FDA) wants targeted in new boosters.

Moderna, in late June, said it should have a bivalent shot targeting those offshoots by early November. However, the “next generation” booster has been approved by the UK stronger antibody responses to BA.5 than Moderna’s current booster, which has been used in the US for nearly a year.

While Moderna is seeking authorization for mRNA-1273.214 in Australia, Canada and the EU, it did not say it is working with the FDA for approval. Some drug industry observers theorize that approving the booster that targeted BA.1, which was dominant in the USin January, would dissuade pharma companies from expediting one that was focused on BA.4 and BA.5.

Omicron’s BA.5 subvariant has been deemed “the worst version” of the virus yet with high transmissibility, but the FDA’s request for boosters that target it has created some confusion among Americans over whether to get a booster when they’re eligible or wait for the updated one.

Doctors say the answer comes down to underlying health conditions. People at risk of severe COVID should get the existing vaccine as a second booster as soon as possible.
