UK approves first bivalent vaccine against COVID-19

The United Kingdom on Monday became the first country to approve Moderna’s bivalent vaccine developed to attack the original Covid-19 virus and the new Omron version, the Medicines and Healthcare products Regulatory Agency (MHRA reported in English).

With this decision, it is expected that the vaccine will be used as a booster in the coming autumn, although the number of doses available is currently unknown.

Health officials had already indicated that from next September, a booster vaccine would be offered to people over the age of 50 and the most at-risk groups.

The original vaccines used during the pandemic were developed to combat the original form of the virus that emerged in Wuhan, China, in late 2019, but the virus has since mutated when new variants have emerged that interfere with the immune system. can escape, which leads to the wrath of evil. in many countries.

With this bivalent vaccine, it is expected that only one injection will be needed once a year in adults.

Known as mRNA-1273.214, this dose is an updated version of the Moderna vaccine given as first, second and booster doses, and is now a UK-approved dose that targets two strains of the virus.

According to the MHRA, side effects from the vaccine are similar to Moderna’s original booster dose and are usually mild.

MHRA chief executive June Raine described the new booster as “a fast tool in our arsenal” to protect the UK from COVID-19.

“I am pleased to announce the approval of the Modern Bivalent Booster Vaccine to provide a robust immune response against the Omicron BA.1 variant as well as the parent 2020 strain,” Raine said.

Moderna’s chief medical officer, Paul Burton, said the new injection could elevate a person’s antibodies to such high levels that it may only be needed annually.

Moderna CEO Stefan Bansel described it as a “next-generation COVID-19 vaccine” that will “play a key role in protecting people in the UK against COVID-19” over the winter.

“We are delighted with the MHRA authorization of our next generation COVID-19 vaccine, Spikevax Bivalent Original/Omicron,” Bansal told the media.

“This represents the first authorization of a bivalent vaccine containing Omicron, further highlighting the dedication and leadership of UK public health authorities in helping end the COVID-19 pandemic,” it said.
