'It's unlikely that existing vaccines will work against new coronavirus variants,' experts explain.

Due to the epidemic of the new coronavirus mutant, the number of newly infected people with the new coronavirus infection (COVID-19)

exceeds 50,000 every day in the United Kingdom, and the total number of infected people in South Africa exceeds 1 million . 'Existing vaccines may not work for mutants,' said Richard Ressel, who led the identification of South African mutants, 'existing vaccines do not work for mutants.' It's unlikely. '

The new coronavirus variants have been identified a large number, was discovered in South Africa that 'infection force is strong' are 'among the 501.V2 and' has been discovered in southern England ' B.1.1.7 particular fury is.' I'm shaking. Several experts, including Associate Professor Simon Clark of Letting University and Professor Lawrence Young of the University of Warwick, have expressed concern about these variants that 'existing vaccines may not work.' In response to these concerns, British Health Minister Matt Hancock also said, 'I am very very concerned about the mutant.'

In the midst of doubts about the effectiveness of vaccines for potent variants, Richard Ressels of the KwaZulu-Natal Research Innovation Sequencing Platform, who played a central role in identifying 501.V2, said, 'Mutations. It is unlikely that existing vaccines will work on the species. '

Ressels said that although 501.V2 has mutations in sites involved in the production of neutralizing antibodies, it may affect the effectiveness of the vaccine to some extent, but existing vaccines induce a wide range of immune responses. He explained that it is very unlikely that the existing vaccine will be completely ineffective because it is effective against multiple sites of the virus. He said he would be able to announce the results of the preliminary study at the end of the second week of January 2021.

Mike Ryan, executive director of health emergencies at the World Health Organization, and Maria Vankel Hove, director of the Emerging Infectious Diseases Division, said, 'The mutants have not changed the way the virus is transmitted, and the current vaccine works. There are no signs that it isn't there. This is very good news. ' BioNTech, which developed the new coronavirus vaccine ' BNT162b2 ' in collaboration with Pfizer, has announced that 'a vaccine tuned for mutants will be completed within 6 weeks.'
