An analysis was published by British academics Official UK Government Scientific Advisory Committee, They believe it is “almost certain” that a variant of SARS-Cov-2 will come out and “lead to the failure of the current vaccine”. SARS-CoV-2 is a virus that causes COV-19.

The analysis has not been equally reviewed, the initial research is theoretical and there is no evidence that such a variation is now in circulation. Such documents are published as “pre-printed publications that provide quick evidence to the government during an emergency.”

The newspaper was dated July 26 and published by the British government on Friday (30).

Scientists wrote that since the eradication of the virus was “impossible” they had “high hopes” that variations would continue to emerge. They say it is “almost certain” that the gradual or stopped accumulation of antigenic variant will eventually lead to the failure of the current vaccine.

They suggest that authorities reduce the spread of the virus as much as possible to reduce the chance of a new vaccine-resistant strain.

They also recommend that research focus on new vaccines that not only hospitalize and prevent disease, but also “trigger high- and long-lasting mumps immunity.”

The goal should be to “reduce the risk of infection and transmission in vaccinated individuals” and “to reduce the likelihood of differential selection in vaccinated individuals.” Research is already underway at several companies that make Govt-19 vaccines to handle new strains.

Comments were made in an article entitled “A panel of academics on the long-term evolutionary scenarios of SARS-CoV-2” and discussed and published by the UK Scientific Advisory Committee on Emergencies (SAGE).

Some variations that have appeared in recent months “show less impact on vaccine-acquired immunity, although nothing seems to escape completely.”

But they warn that these variations appeared “before the spread of the vaccine” and that “as vaccines become more widespread, it will increase the transmission benefit obtained by a virus that can prevent vaccine-acquired immunity.”

This is an issue that SAGE has already warned about.

In the minutes of the July 7 meeting, SAGE scientists wrote that “a combination of high prevalence and high doses of the vaccine creates the conditions for the emergence of immune survival variation.” He said at the time that “the probability of this happening is unknown, but such a variation would pose a significant risk in the UK and internationally.”
