Omicron-adapted Moderna bivalent vaccine approved in Great Britain


Local weekly Mladina reports: In Great Britain, regulators have approved an updated vaccine against Covid_19 manufactured by Moderna, first of its kind to be given the green light, which should work against both the original version of the new coronavirus and the omicron. It will be intended for adults as a booster dose.

According to the head of the Medicines and Healthcare products Regulatory Agency (MHRA), June Rain, it has been shown in clinical testing to stimulate a strong immune response against both the original virus and the omicron.

The vaccine should also trigger a good response against two sub-variants of the omicron, BA.4 and BA.5, which to a certain extent are behind the latest wave of new infections in Europe and the USA. Side effects are said to be mostly mild, as with the company’s original vaccine.

Although vaccines have made a significant contribution to reducing the number of hospitalizations and deaths due to covid-19, which first appeared in China in late 2019, according to health and government institutions, currently available vaccines work mainly against the first variants of the virus.

Moderna’s new vaccine, meanwhile, is half-targeted at the original 2020 form of the virus and half-targeted at the micron version, officially known as BA.1.

As the company announced in June, the new vaccine works better against omicron and against the first variant than its first covid-19 vaccine, called Spikevax.

The European Medicines Agency (Ema) also announced this month that it had started a review of this vaccine. At the same time, it is studying a similar adapted vaccine from Pfizer/BioNTech, which could be approved as early as this fall. It is aimed at the BA.4 and BA.5 sub-versions.

Thus, the other omicron subtypes both usually cause a milder course of the disease, because they affect the lungs to a lesser extent, but mostly remain in the area of ​​the upper respiratory tract.
