Do you protect the dose of the third Corona vaccine from Omekron?

Is the vaccines able to face the omicron of the Corona virus?And why do some scholars fear that it is not effective?Is the third dose of the vaccine protect against omekron?

Are the current vaccines able to face the omekron dynasty?

Scientists need more time to make sure;"What we do not yet know is the extent of the infection it will be, and the success of our vaccines, and if it will cause a more severe disease," said the director of the American Centers for Disease Control and Prevention, the doctor, scientist Roshil and Al -Naski on Sunday.

She said, "We really hope that our vaccines will succeed, as if it does not succeed in preventing the disease completely, it completely prevents infection, as it can prevent exposure to severe disease and prevent people from entering hospitals."

On the "ABC" program "ABC", the American TV network, Al -Naski stressed that the more dynastic mutations increased, the greater the need for further immunity to prevent infection, adding, "We are actually proceeding to vaccinate more individuals and more of them in revitalization doses".

"We know that the virus has a lot of mutations and many of these mutations are related to more infection."

Experts believe that the next few weeks are crucial in understanding if the omekron dynasty represents a great danger, and does it respond to the current vaccines.

A study of epidemiological data in South Africa revealed that the risk of returning the new Corona virus is 3 times compared to the other strains of Corona, according to the Bloomberg Agency on Thursday, quoting a statement via the South African Center for Epidemiology and AnalysisAnd the National Center for Infectious Diseases.

Bloomberg quoted the authors of the study: Juliet Polly and Harry Molitri as saying that the results demonstrated the existence of epidemic evidence of the ability of omecron to evade immunity acquired from the previous infection.

"I think there is a high possibility that we will witness a decrease in the effectiveness of the vaccine," said Stephen Hoj, President of Moderna, in a statement to the American ABC.

He added that "what I do not know is the level of" retreat, and asked: "Will it be like what we have seen with the Delta, which the vaccines have been effective against, or will we witness a decrease in the event by about 50%, which will mean that we must adjust the vaccines?"

Our Modern - like other pharmaceutical companies, including Pfizer - started working to adapt its vaccine if necessary.

The emergency director of the World Health Organization Mike Ryan said last Friday that there is no evidence that supports the idea of changing the Kofid-19 vaccines so that it is appropriate to resist the omeirron dynasty.

Ryan added - during an event carried by social media - that, although - and if necessary - work is already underway in the event of the need for vaccines for omecron.

"Now we have very effective vaccines," Ryan said. "We need to focus on distributing them more fairly. We need to focus on the most vulnerable groups on vaccination," Ryan said.

The head of the German company Biontech, Augur Shaheen, said at the Reuters Cast - last Friday that his company may be able to adjust its anti -Corona virus vaccine relatively to combat the new axis Omekron.

He also added that the vaccines will continue to protect against the severe symptoms of the disease despite the mutations.

Benette in cooperation with Pfizer was produced by one of the first Anti-Coveyd-19 anti-vaccines.

"This strain may be able to infect the two restaurants. We expect that the injured who received vaccination will enjoy the protection from the severe symptoms of the disease."

He pointed out that the virus mutations mean that vaccinations are likely to become annual, as is the case with seasonal influenza.

Why do some people fear that the current Corona vaccines will not be effective against omecron?

The answer is in a study published last September - in many ways - the emergence of a variable such as omecron, that is, a variable with a very large number of mutations, and the study also provides important visions about the effectiveness of vaccines against omecron, according to a report on the "NBR website(NPR).

In the study-which was published in the journal "Nature"-the scientists were trying to understand how the Corona virus-its scientific name SARS COV-2-learned to outperform the antibodies.

So the scientist Paul Pinzaia and his colleagues designed a super version of the virus, although it is not the full virus, only part of it was specifically.They focused on the notorious part of the virus, Spike Spring protein, which is associated with human cells and is a target of important antibodies.

The researchers took about 20 booms and all put it together in one spike protein, which they call "multi -property spinning".These mutations have already appeared in many variables around the world, but they were not all together.

"These are the mutations that occur naturally and we have merged," says Pinas.It has been proven to help the virus avoid detection of antibodies.

Interestingly - as Benias says - the omecron variable contains many of the same mutations such as this thorny multi -property protein, but he says it has more mutations, as instead of only 20 booms on spike protein, omecron contains about 30.

After that, Benias and his team took anti-people from people who took two doses of the "MRNA" vaccine-such as the Vizar and Moderna vaccines-or previously suffered from the Kofid-19 infection, and tested these antibodies against a multi-specific spike protein.

"This thorny multi -property protein was almost completely resistant to the anti -equivalent antibodies in these two groups of plasma," Benyas says."On the basis of these results, we expect that omecron will be a large resistance to the antibodies that spread in individuals who have convalescence or who have obtained the immoral RNA vaccines, and it is clear that the volume of allergic loss of these antibodies must be applied experimentally."

The image is not negative

"We are optimistic about with caution that after 3 doses, you will get some useful protection," says Dr. Michael Dolketin.

The virus scientist Jeremy Le Pen at the Us Chan College says that the hope is that protection from severe diseases and hospital entry will continue.

"The antibodies are the basic tool that your body uses to stop the initial infection of the Corona, but even if the effectiveness of your own antibodies is 10 or 20 times, it may remain enough to prevent you from going to the hospital."

In addition, there are other ingredients for the immune system, such as T -cells, which can quickly get rid of infection if they occur;Consequently, it helps protect you from serious diseases in general, it is unlikely that the TV cells will lose their effectiveness when the virus mutates.

For example, Dr. Antonio Bertoletti and his team at Duke Nass College of Medicine have preliminary data showing that T -cell activity is still very high even against a multi -cell -like spike protein created by Benias and his colleagues.

"In summary: the image does not seem horrific for T -cells," said Berutletti Laboratory members on Twitter.

Is the third dose of the Corona vaccine protecting from omekron?

Anthony Vochi's chief medical consultant, Anthony Vochi, the chief medical consultant for the White House, epidemic scientists, Anthony Vochi, says the third vaccine dose) is the best defense against the new omekron breed and a very transitional Delta strain, according to a report in NBC to Berkeley Loving Junior.

Last Friday, Vochi said-in the Kofid 19 response team at the White House-that studies show that an additional dose of current Kofid vaccines will increase the levels of antibodies against all breeds, adding, "There are all reasons for the belief that if you are vaccinated and enhanced, you will get at least to a degree.Certain from mutual protection (protection from another breed of the virus), and it is very likely against severe disease, and even against the omekron variable.

Is it possible to use the same current vaccines?

تعمل لقاحات فايزر-بيونتك ومودرنا وجونسون أند جونسون (Johnson & Johnson) على لقاحات خاصة بأوميكرون لاستخدامها ضد المتغير الجديد إذا أظهرت الاختبارات المعملية انخفاضا كبيرا في الحماية من الأمراض الشديدة، رغم أن الأمر قد يستغرق شهورا قبل أن تكون جاهزة للتوزيع.

However, there is still a discussion among some health experts about whether it is appropriate to use current vaccines as reinforcements against new and emerging strains, as vaccines are still designed to target the original shape of the virus that was identified in late 2019.

Dr. Paul Ofit, a vaccine expert at the Children's Hospital in Philadelphia, said that if the question is continuing to reinforce a vaccine, it mainly aims to conduct an immune response against the ancestral strain (the original valor of the Corona virus), so will this limit the body's ability to achieve an immune response to a virus that is very different from its predecessors (Any omekron strain).

Ofit describes a phenomenon called by immune scientists "Origenic Sin", where the body's immune system relies on the memory of its first meeting with a virus, which sometimes leads to a weaker immune response when he later faces another version ofThe virus.

OFIT - also a member of the Consultative Committee for the Food and Drug Administration - said that vaccines can also activate this phenomenon, and examples of this is the HPV.OFIT added that, in theory, it can apply to Kofid-19 as well.

He said that some experts have argued that it may be the best for those who are not at risk of developing a very waiting disease for a reinforced dose until there is a specific option.

Ofit - with Philip Crawrus and Marion Grober, two former US Food and Drug Administration officials - wrote an opinion article published on Monday in the Washington Post newspaper that argues that augmented injection should be limited to those who are at risk of serious diseases, such as seniorAge and those who live or work in very dangerous places, such as health care workers.

They said that the two original doses of the Rana Mercy vaccines (Pfizer-Peppertec and Modenna) are still working with most healthy adults.

Eyeen Foxmann, Yale University, said that even if the reinforcement of the original vaccine has made future vaccines less effective, it is not wise to wait for a specific variable dose to get a batch.

She said that the end is that there is a life virus that still spreads throughout the country, and it has been proven that the current vaccines protect it.

Will the current shot be good as it was against the original virus?She says, perhaps not, but she will provide at least some protection against her.

Are you receiving the dose to promote protection from omekron?

The answer follow the vaccination instructions in your country, if the health authorities in your country are directed to obtain the third dose, you should receive it.

It is clear that the doses reinforced from the Corona vaccines raise the levels of antibodies, strengthen the body's defenses against infection, and may help compensate for any advantages gained by omecron through development.

Additional doses may also slow down - at least - which leads to saving time for vaccine makers to develop a composition for omecron, if necessary.
