New Vaccine Studies Continue for Possible Covid Variant

Vaccine companies after the Delta variant that messed up in the last period of the Covid-19 era to another possible variant continues with the preparations. Pfizer, Moderna and AstraZeneca; against delta and other known variants of the vaccines they produce. that it is effective asserts. It is possible to see that these vaccines are effective in the rate of hospitalization and avoidance of severe diseases.

But Paul Bieniasz, a virologist at Rockefeller University in New York, said: “If we’re going to get herd immunity through vaccines, eventually we’re going to have to for Covid variants.” we will have to produce new vaccines. We are currently not in a position to predict the next evolution of the virus. Therefore, examining existing variants seems like a logical approach.” made a statement.

Variant-specific vaccines are under testing:

The vaccines currently produced and offered to the public by Pfizer, Moderna and AstraZeneca were first detected in Wuhan, China. SARS COV-2 It was developed for the virus, and scientists argue that these vaccines are also effective against subsequent variants. RNA vaccine manufacturers such as Pfizer and Moderna should a possible new variant emerge. they will be able to produce the first prototype vaccines in a few days envisaged.

In order for these vaccines to be made available to the public, they must first be tested on humans, which is a time-consuming process. Pfizer, one of the vaccine companies that tested the vaccines it developed specifically for Delta and Beta variants in August, participated in a group of 930 participants. Exclusive to Beta variant only Also called an RNA vaccine. Moderna and AstraZeneca are also continuing to conduct vaccine trials for the Beta variant. The main reason why vaccine companies focus on the Beta variant; be more resistant to vaccines due to mutations it carries. Scientists think that by examining the Beta variant, they can put the information obtained in a possible Covid mutation into practice.

Vaccine companies state that these trials and research are not for a currently existing variant, but for a possible variant that current vaccines do not work with. As a result of these studies, it is hoped that Covid-19 vaccines against new variants will be produced as quickly as flu vaccines.
