US military scientists investigated new UK coronavirus version to see if it could be resistant to the vaccine


While there is always a concern that a vaccine will not work if the virus changes significantly, Walter Reed scientists still hope that the vaccine will be effective against this new version, Drs. Said Nelson Michael, director of the Research Center for Infectious Diseases. Walter Reed Army Institute of Research.

“It is for this reason that this mutation is not a threat, but you never know. We still have to be diligent and keep looking,” Michael said.

On Thursday, the Walter Reed team began investigating genetic sequences for the new UK version posted online by British researchers.

They are doing a computer analysis as a first step.

“Computer analysis will allow us to determine how much we should be concerned,” Michael said. “Other teams around the world are also doing this analysis.”

If computer analysis shows that there is a concern, the study will need to determine more definitively in the laboratory and in animals whether the vaccine will work on this variant.

At a press conference on Saturday, the new holiday lockdown was announced in parts of England by British Prime Minister Boris Johnson, who has seen the spread of the new mutation.

Kovid-19 vaccine may not be safe and other myths

“There is no suggestion that the vaccine will be less effective than the new variant. Our experts will continue to work to improve our understanding.”

Britain’s chief scientific advisor agreed.

Dr. Patrick Valence said at the press conference, “Our scientific belief at the moment from all scientists is that the vaccine response to this virus should be sufficient.”

The US Food and Drug Administration has authorized two vaccines, one by Pfizer and the other by Modern. Both novels work by creating a genetic blueprint for the spikes that appear on the surface of the coronovirus. The immune system “sees” the spikes and learns how to launch an attack against it.

Like other new variants or strains of the Kovid-19, it carries a genetic fingerprint that makes it easy to track, and is one that is now common. This does not mean that the mutation has spread it more easily, nor does it mean that this variation is more dangerous.

Many experts in the genetics and epidemiology of the virus are noting that this may be a “lucky” strain that has been amplified due to the superspreader event; It can be a mutation in any way and spreads it more easily without causing more serious disease; Or it can happen just by coincidence.

In August, the Walter Reed team published a study showing that vaccines still work against many other mutations of coronovirus.

Vaccines are still useful because viruses are constantly mutated, but usually not in ways that would render a vaccine useless, Dr., an advisor to the US Center for Disease Control and Prevention on Vaccines. William Scheffner said.

“Even with mutations, the virus remains essentially the same,” Scheffner said. “It’s like with a person. I can change my brown coat for a gray coat, but I’m still Bill Scheffner. I’ve changed something, but I’m still the same person.”
