The new variant of the coronavirus that emerged in South Africa has caused a worldwide sensation.

Almost all countries in the world have imposed travel bans on South Africa and its surrounding areas to prevent the virus from entering their country.

The World Health Organization (WHO) has raised the possibility of the further spread of omega-Cron variants worldwide, and stated that because the Omi-cron variants may have serious consequences, the number of coronary artery cases may increase in the future.

The Corona Vaccine Company has stepped in to deal with the threat of the Near River Coronavirus, trying to figure out how effective the Corona vaccine they have developed against the new variant, because it was initially said that the Near River Coronavirus variant has undergone so many changes that it may not be subject to the vaccine. Influence.

In this regard, experts recommend that the third dose of the new crown vaccine be started immediately, and then Pakistan, the United Kingdom, the United States and other countries around the world will start to receive the third dose of vaccine in stages.

But Dr. Albert Borla, chief executive officer (CEO) of the US pharmaceutical company Pfizer, said that this matter may go beyond the scope of the third dose, and a fourth dose of vaccine may be needed to deal with omega -Rs 3 crore risk.

He said that a fourth dose may be needed within one year of the third dose of corona vaccine.

Even before Dr. Albert O’Malley came to Crown, someone suggested that the elderly should receive a dose of the new crown vaccine every year.

Now the CEO of Pfizer says that those who are more susceptible to the coronavirus will need to be vaccinated twice within a year because this type of coronavirus has changed too much. The vaccine has lost its effectiveness, and two doses are no longer enough. .

The person in charge of Pfizer said that three doses of the new crown vaccine can provide the best protection against code 19, but experts cannot be sure how quickly this protection will disappear. might need.

He said that before Omi Kron came, I said that the fourth dose should be given a year after the third dose, and the fourth dose may be needed soon.

Earlier in the day, Pfizer stated that two doses of corona vaccine are not enough to prevent omeprazole, but it can prevent corona complications. Experts later stated that the same was true for vaccines from other companies.

Since the outbreak of the new crown epidemic, Pfizer and other companies have earned billions of dollars. In recent days, Pfizer said that if its global vaccines cannot prove to be more effective for omega-Crohn, then a vaccine-specific vaccine for omi-cron. May have to wait until March next year.

Pfizer said that after the booster dose, the number of antibodies in the body that resist Omega Kroner increases by up to 25 times.

Why is Omi Kroon dangerous?

It is said that it is more dangerous than its predecessor, the coronavirus variant, because it has the potential to spread quickly and the vaccine will be less effective.

South African health officials said that this new variant has many changes that scientists did not anticipate. Compared with the original coronavirus, this variant has about 50 mutations, 30 of which are located in the spike protein.

Vaccines developed so far have been attacking the spike protein of the virus in order to destroy the virus before it enters the human cell. With so many changes in the spike protein, available vaccines reduce the impact of this virus by as much as 40%.

Careful observation revealed that the receptor binding domain part of this variant (the part where the virus first attaches to human cells) has undergone 10 changes, while the original coronavirus is in the devastating Delta variant in India and other parts of the world. In contrast , There are only 2 changes.

How many variants of Corona were there before?

Since the first SARS CoV-2 was introduced in China, there have been 5 variants of the coronavirus. The first variant was named Alpha, and it was found throughout the United Kingdom, also known as the British variant.

Then there are the beta variants. This variant appeared in South Africa and then spread to other countries in the world.

Then came the gamma variant that spread to Brazil, and then the delta variant caused severe damage in India.

There is now a fifth variant, which is named OMICRON.

How to avoid this situation?

Fortunately, South African health experts said that so far, this new variant has not shown serious symptoms, and the affected people have already developed mild symptoms of the new crown.

As with other variants of the coronavirus, precautions must be taken to avoid it. The basic SOPs for coronavirus must be followed, namely wearing masks, washing hands frequently, social distancing, etc.

All of these preventive measures are necessary until data on the effectiveness of the vaccine against this variant is exposed. If the existing vaccine is effective against this variant, it will be overcome soon, otherwise scientists will have to modify the vaccine based on the new virus.
