Scientists have confirmed the vaccine's effectiveness in the new strain VUI - 202012/01 of the worldwide corona spread from the UK. In contrast, the impact of the vaccine against the strains 501VU and 484 found in South Africa is not confirmed. Scientists say that when the virus changes the structure of its protein, the body is unable to recognize it even after being vaccinated. Because of this, there may be a risk of infection in the new strain of the corona.
Worrying: Changes in the protein of South African strains reduce vaccine opportunities
Sir John Bell, a professor at the Department of Forest Medicine, senior scientist at Oxford University, points out that the corona vaccine trains the body's immune system to fight pathogens. Vaccine antibodies make and preserve proteins so that in the future they can start fighting against those types of viruses.
If the virus has mutated then the protein of the vaccine will not be recognized and the person will be infected again. In such a situation, the impact of the vaccine on those who are affected by South African strains is difficult. Because this strain of the virus has changed its protein.
The danger for more infectious strain vaccine
Professor John points out that the change in the protein of the South African strain of the virus is worrisome. The vaccine will work against the UK strain, but nothing can be said about what it will do against the South African strain. The question has arisen about this. Many scientists say that there are similar strains in Nigeria that are more contagious.
Other countries now have to be more vigilant
Professor François Balloux, director of the Institute of Genetics at University College London, says that all countries in the world need to be more careful. People coming from countries like South Africa, Britain, Brazil have to undergo genome sequencing with a coronavirus test. The advantage of this will be that in time a new form of this virus will be identified. If anyone fails to do so, then it will directly affect the preparation for vaccination.
The virus changes its protein
Professor John clearly states that the vaccine against South African strains is likely to be neutralized. The South African strain of the virus is more worrisome than the strain found in Britain's cant. This is because two cases have been found in the UK and it has been found that the virus has changed its protein structure significantly, which can neutralize the vaccine against it. Pro. John has a key role in the preparation of the Oxford-AstraZeneca vaccine.
Identification of new strains difficult due to investigation
Cellular microbiologist Doctor Simon Clarke of the University of Reading explains that RT-PCR identifies the virus's S gene, N gene, and ORS1AV gene. The UK strain has the S gene. It is clear that in which only two genes of the virus are found, there is a new strain in it. The samples of the infected have all three genes. Meaning he is infected with the old strain. There are three genes in the South African strain, so it is very difficult to identify the new strain.
