UK Approves Updated Covid-19 Vaccine From Moderna, Targets Omicron And Original Strain 

The United Kingdom has become the first nation to approve an updated version of Moderna’s Covid-19 vaccine booster, meant to target the omicron strain as well as the original virus that first appeared in 2020. 

“An updated version of the COVID-19 vaccine made by Moderna that targets two coronavirus variants (known as a “bivalent” vaccine) has today been approved for adult booster doses by the Medicines and Healthcare products Regulatory Agency (MHRA) after it was found to meet the UK regulator’s standards of safety, quality and effectiveness,” read an official government release.

“Half of the booster, called Spikevax bivalent Original/Omicron, targets the original coronavirus strain while the other half targets Omicron,” it said.

The MHRA, the UK government’s independent expert scientific advisory board, endorsed the decision to approve of the new vaccine after carefully reviewing the evidence. 

The clinical trial by Moderna reported that the booster targets Omicron and showed a stronger immune response against the variant in addition to the original strain. The company said the “updated booster showed a potent response against BA.4 and BA. 5 sub variants.” 

“The side effects are the same as for the original Moderna booster dose and found to be typically mild and self-resolving. No serious safety concerns were identified,” the UK government release said.

MHRA Chief Executive Dr. June Raine said that “the new Moderna booster will help keep communities protected.

“The first generation of COVID-19 vaccines being used in the UK continue to provide important protection against the disease and save lives. What this bivalent vaccine gives us is a sharpened tool in our armory to help protect us against this disease as the virus continues to evolve.”

The UK’s Joint Committee on Vaccination and Immunization will advise on the vaccine’s rollout, as it is not yet clear who will be offered the booster or when. 

Stéphane Bancel, Chief Executive Officer of Moderna, said on Twitter he was “delighted the vaccine had been approved.”

“This represents the first authorization of an Omicron-containing bivalent vaccine, this bivalent vaccine has an important role to play in protecting people in the UK from Covid-19 as we enter the winter months.”

Besides Moderna, Pfizer and BioNTech have been testing two Covid-19 vaccine boosters that will also target the Omicron variant.
