Covid-19 new variants 2021

Hello friends. How are you all? Hopefully everyone well in this covid-19 situation. The more days go by, the more terrible it is. This has created many more new variants of the Corona.

Which are much more powerful than the previous variants. So today we will tell you about the new variants of Corona.

All eyes are now on mutations in the corona virus, as new types 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?:-

In order for survival and reproduction, all the viruses undergo changes in the body, most of the time these changes are very subtle.

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 the immune system by mutating itself.

>>>How does the new variant change itself?:-

UK, South Africa, Brazil or Indian - all variants have changed their body spike protein. It is a part of the virus through which it can enter the human body cells. .

A mutation known as N501Y has been shown to give the virus special benefits in the case of infection and proliferation in cells.

Some experts believe that the UK / Kent variant is 80% more contagious, although Public Health England says it is 30% -50% contagious.

A significant mutation called E484K has also occurred in the South African and Brazil variants. This allows the virus to escape from the antibody.

You may know that antibodies are an important part of the body's immune system. Experts say such changes have been noticed recently in the UK variant.

The India variant has also undergone some significant mutations which may have disrupted the immune system. That is why scientists are now conducting research on it on an urgent basis.

>>>Will the vaccine work against the new variant?:-

The vaccines that are now available were developed to treat the original type of corona. However, scientists say that these will work against the new variant, but its effectiveness will be less.

According to a study, those who have had covidosis 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 data, it is equally effective against the UK / 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 government of British has contracted a pharmaceutical company called Kiorvac to develop vaccines for future Corona variants. Five crore dose of vaccine has also been ordered in advance.

Depending on what changes will be made to the variants in the future, the elderly and people with obvious physical problems will need such a booster ticker by the end of this year.

Last words:-

I hope you have learned a lot about all the new variants of Covid-19. So we all have to follow the health rules and use masks when we go out of the house. If you like the article, please share. Stay healthy everyone. Thanks.
