Europe’s drug regulator set to approve Moderna and Pfizer Omicron boosters this week

A formal approval by the European Commission, the EU executive, is expected later this week. The move comes as governments around the world gear up for fall booster campaigns. The US Food and Drug Administration authorized Pfizer-BioNTech and Moderna shots designed to target the latest Omicron subvariants, BA.4 and BA.5, on Wednesday.

Once they get the green light, the drug companies will be able to supply vaccines “within days,” with Germany expected to start offering updated shots next week, and France planning to administer shots alongside a flu campaign in October, Liese said. Although not a silver bullet to stop the pandemic, the updated vaccines will offer better protection, he added.

Doctors had previously been relying on booster doses of the original vaccine to shore up protection against Omicron. As the virus has mutated it has been able to sidestep immunities generated by existing shots and has caused more breakthrough infections, although most only resulted in mild disease.

Earlier this month, the UK became the first country in the world to approve Moderna’s omicron-adapted shot and said it boosted the arsenal of vaccines available to fight an evolving virus. However, British health authorities also said people should take whatever booster shot is offered to them as all shots, including the original versions, still offer very good protection against severe illness from COVID.

Pfizer and BioNTech have also sought approval in the EU for their bivalent booster that targets the BA.4 and BA.5 Omicron subvariants, the version that will be sold in the US Moderna also plans to submit that version of its booster to European authorities for approval, a spokesman said.
