Vaccines strike. Global health: look for other effective ones

Despite the rush of well-known vaccine companies, as well as most countries around the world, to give a third booster dose against the emerging corona virus, the reality does not bode well.

On Tuesday, experts from the World Health Organization warned that only giving vaccine booster doses was not a viable strategy for dealing with emerging mutants, and they called for new vaccines that better protect against transmission.

The World Health Organization’s COVID-19 Technical Advisory Committee said in a statement there is a need to develop highly effective COVID-19 vaccines to prevent infection, transmission, acute forms of infection and death.

Start with Pfizer

These developments came after Pfizer revealed production of a vaccine targeting the mutated strain by next March.

Company chief executive Albert Borla said on Monday that a vaccine was needed and his company could produce one, according to Reuters.

He also added that Pfizer and its partner Biontech are working on both a version of the vaccine targeting Omicron and one that includes both the previous vaccine and another resistant to the rapidly spreading strain.

“I think that’s the most likely possibility. There are a lot of things we’re working on as we speak,” said Borla, speaking at this year’s JPMorgan annual online healthcare conference.

In addition, he indicated that Pfizer could seek approval from U.S. regulatory agencies for a registered vaccine and could launch it as soon as, perhaps next March.

Moderna is frustrated .. the third may not be enough

While Moderna CEO Stephan Bancel revealed in a frustrating statement that the effectiveness of the Corona virus booster vaccines will likely decrease over time, and people may need a fourth dose in the fall. to increase their protection.

He added that people who received their boosters last fall are likely to have enough protection to get them during the winter, when new infections increase as people congregate indoors to escape the cold. , given that the effectiveness of boosters will likely decrease over several months, similar to what happened with The First Two Doses, in a journal published by “CNBS” yesterday, Thursday.

Moderna CEO added that governments including the UK and South Korea are already asking for the doses and they are in the works.

Moderna released preliminary data last month showing that the currently authorized 50 microgram booster increases Omicron’s anti-infection antibodies 37-fold and that the 100 mcg booster has increased those antibodies 83-fold.

They have finished their vaccinations.

While the former head of Britain’s vaccine task force had another opinion, as the situation unfolded, he considered Corona should be treated as an endemic flu-like virus, and ministers should end large-scale vaccination campaigns after completing booster dose campaigns.

Dr Clive Dix also called for rethinking the strategy for tackling Corona in the UK, and leading an approach contrary to that which has been taken over the past two years and coexisting with Corona as the “new normal” .

“Mass vaccination in the UK must stop now,” Dix said.

Corona vaccines

It should be noted that booster doses are playing an increasingly important role in public health strategies to control the virus, especially as the protection resulting from the initial two doses has received a heavy blow due to the mutant Omicron .

These developments are rekindling fears that currently available Corona vaccines may not be able to stop the new, highly transmissible mutants, according to Reuters.
