New Covid strain: Genetics experts worry vaccines may not be as effective against UK variants


“This is the first version I’ve seen during the entire epidemic where I took a step back and said: ‘That,'” he recalls.

Health officials have downplayed the possibility that coronovirus vaccines would not work against the UK strain, but Verbobe and other scientists think it is a possibility – and is just a possibility – that this new version is somewhat Tk, externally.

“This is the first edition I have seen that I think is a burning question,” said Verbobe, head of the Department of Ecology and Evolutionary Biology at the University of Arizona.

Trevor Bedford, an associate professor in the Vaccine and Infectious Diseases Division of the Fred Hutchinson Cancer Research Center, is also closely monitoring the UK version.

Large clinical trials have shown that vaccines by Pfizer / BioNTech and Moderna are about 95% effective against novel coronaviruses. However, the UK variants did these tests before starting their explosive growth.

Bedford said he does not believe the vaccine against the new UK strain would be useless, but it could reduce its effectiveness to some extent.

“It could decrease vaccine efficacy from 95% like 80% or 85%,” he said. “It will be a minor effect, not a dramatic effect.”

Health officials have said that there is no reason to think that the vaccine will not work against the new version.

“[There is] Health Assistant Admiral Drs. Brett Girir said on Monday that there is no evidence of this suggestion nor is there any reason to believe that the vaccines we currently have will be vacated.

“I think it is very unlikely in the UK, especially, to avoid vaccine immunity,” said Monsep Saloi, head of Operation Tana Speed ​​on Sunday.

But some scientists point out that this mutation is not like others who have done it before.

“We should not immediately jump to the conclusion (as many have done) that it Is not One concern, “Christian Anderson, a professor in the Department of Immunology and Microbiology at Scripps Research Anderson, wrote to CNN. We just don’t know at this point in time – but we should know soon.”

Bette Kurber, a scientist at the Los Almos National Laboratory, is also investigating this type of version.

Bette Korber, a scientist at Los Almas National Laboratory, asked if the new mutations are a concern for the vaccine, saying “mutations are really worrying, they need to be investigated.”

According to the CDC, the UK variant has an unusually large number of mutations – 14 changes and 3 deletions in its genetic code that affect the building blocks of its proteins.

“This virus has 17 unique mutations that have not been seen elsewhere, and it is really unusual,” Warboe said.

British scientists reported last week that there have been allegations of 14 lineage-specific amino acid substitutions for the Kovid-19 pandemic, which, to date, are unprecedented in global virus genomic data.

It is not just the number of mutations that some scientists are concerned with, but also the way they can work together.

“Many of these mutations have been characterized in the laboratory and we know little about them. However, their combination (along with other changes) is not characterized,” Bedford tweeted on Tuesday.
Pfizer and Moderna are testing the vaccine to see if it works against the new version.

BioNTech CEO Dr. Ugur Sahin said that he does not think there will be a problem with the new variants, but if it does, the vaccine can be updated.

“We should not forget that we still have the opportunity, if necessary, to properly adjust the vaccine for this new virus version, if it is necessary,” Sahin said. “I don’t think it is needed. But if it will be needed, there is a technical possibility to do so.”
