All eyes are now on the mutations in the coronavirus – newer variants of Covid-19 are spreading rapidly, more and more people are being infected with them, and the ability to block vaccines is even greater than these variants.

Why does the mutation of covid occur?

All viruses undergo mutations in order to survive and reproduce. Most of the time these changes are terribly refined. Sometimes it is the virus that causes the damage. However, when major mutations occur in others, the disease becomes more contagious and increases the patient’s risk. When a person’s immune system is weakened by an infection or a vaccine, the virus breaks down that immunity by mutating itself. To find out how dangerous a virus is, scientists look at the virus’s genetic code, its behavior in the laboratory, and its transmission to humans.

What do we know about the different variants?

Thousands of variants of the coronavirus have spread around the world. But the UK, South Africa, and Brazil variants are considered “worrying variants”. The UK or Kent variant (another name for B.1.1.7) was first seen in Britain. This variant has since spread to more than 50 countries. And it’s still mutating. The Brazil variant (P.1) has unfolded to quite ten countries. This includes Britain. As many as 200 cases of India variant (B.1.617) have been registered in Britain till April 26. However, scientists believe that this has nothing to do with the current wave of the Covid-19 epidemic in India. Today Magazine

Is the new variant more dangerous?

No evidence has yet been found that most of those who have been infected with these variants have higher levels of the disease. As seen in the case of the original form of the corona, the elderly and those with physical problems are also at higher risk in these variants. But for people who have not been vaccinated, the risk of dying from a more contagious virus is higher. Some studies have shown that individuals with a UK variant have a 30% higher risk of death. However, the evidence is not very strong. But for all types of corona strain, doctors advise the same: wash hands well, maintain social distance, use face masks, and ensure ventilation indoors.

Will the vaccine work against the new variant?

The vaccines that are currently out there were developed to treat the initial style of the corona. However, scientists say that these can work against the new variant, however, its effects are less. According to a study, for those who have had scoliosis before and have some immunity, the Brazilian variant may be able to block their body’s antibodies. Preliminary laboratory data and patient data on Pfizer’s vaccine show that it works against newer variants, but is less effective. According to Oxford-AstraZeneca information, it’s equally effective against the United Kingdom / Kent variant. However, it offers less protection against the South African variant. According to some preliminary results, the modern vaccine is effective against the South African variant. However, its immune response is weak and short-lived.

Do I need a booster vaccine for the new variant?

The British government has entered into an agreement with a pharmaceutical company called Kiorvac to develop vaccines for future Corona variants. Five crore dose vaccine has also been ordered in advance. Depending on how the variants change in the future, the elderly and people with obvious physical problems will need such a booster ticker by the end of this year. All eyes are now on the mutations in the coronavirus – as new types of Covid-19 spread rapidly, more and more people are becoming infected, and the ability to block vaccines outweighs these variants.
