Is it possible to give up wearing a mask after receiving the Corona vaccine?

Can a person who received the Corona vaccination transmit the virus to others?

And why?

We start with the question, "Is it possible to give up wearing the muzzle after receiving the Corona vaccine?", And the answer is no, as the vaccines provide protection by about 95% when receiving two doses, this means that one out of every 20 people, despite getting the vaccine, may develop Covid-19 disease Symptomatic;

Therefore, you need to continue wearing the muzzle to protect yourself from exposure to Corona virus from an infected person.

Coronavirus vaccines also require two injections;

The date of the second injection of the "Pfizer-BioNTech" vaccine is 3 weeks after the first dose. As for the "Moderna" vaccine, the second injection is 4 weeks later.

In general, the effect of vaccines is not immediate, according to the Associated Press report.

People are expected to receive a certain level of protection within two weeks after the first injection;

But full protection may not occur until two weeks after the second injection.

It is also not known whether vaccines generally protect people from infection completely, or only from symptoms.

This means that people who have been vaccinated may still be susceptible to infection with the virus, although it is possible that their susceptibility is much lower, said Deborah Fuller, a vaccine expert at the University of Washington.

Can a person who received the Corona vaccination transmit the virus to others?

This point brings us to the second question, which is "Can the person who received the Corona vaccination transmit the virus to others?", And the answer is that there is a possibility in theory.

For example, a person who received the vaccine for Corona met an infected person, and moved to the person who received the vaccination through the nose, for example, then the body of the person who received the vaccination will attack the Corona virus, which entered the body in the blood, and prevents its spread.

But there is a possibility that the Corona virus in the nose will still be alive and present.

This means that the person who received the Corona vaccination will not have symptoms;

Because his body defeated the virus, but his nose may transmit the virus through the droplets.

And if these droplets are transmitted to a person who has not received a Coronavirus vaccination, he may develop Covid-19.

In fact, this scenario has led some scientists to worry that vaccinated people will become the silent spreaders of the Coronavirus, as they may continue to spread it in their communities.

This puts unvaccinated people at risk, according to a report in the "New York Times".

In most respiratory infections, including the emerging coronavirus, the nose is the main entry point.

The virus multiplies quickly there, and stimulates the immune system to produce a type of antibody specific to the mucous membrane, which is the moist tissues lining the nose, mouth and lungs.

If the same person is exposed to the virus a second time, those antibodies, as well as the immune cells that remember the virus, quickly suppress the virus in the nose before it has a chance to infiltrate an object.

Muscles

On the contrary, coronavirus vaccines are injected deep into the muscles, to stimulate the immune system to produce antibodies, and this appears to provide adequate protection to prevent the vaccinated person from contracting the disease.

Although some of these antibodies will circulate in the blood to reach the mucous membrane of the nose, and stand there for guard, it is not clear whether the amount of antibodies is sufficient to prevent the reproduction of the Corona virus in the nose.

If this reproduction occurs, the person can transmit the infection to others by sneezing or breathing.

"It's a race that depends on whether the virus can replicate faster, or the immune system can control it faster ... It's a really important question," Immunologist Marion Bieber at the University of Washington in Seattle told the New York Times.

Only people who have a large amount of coronavirus in the nose and throat are expected to transmit the virus, and the lack of symptoms in immunized people who have been infected indicates that the vaccine may have kept virus levels under control.

But some studies have indicated that even people without symptoms can have large amounts of the Corona virus in their noses, as indicated by Dr. Yvonne Maldonado, who represents the American Academy of Pediatrics, at meetings of the Federal Advisory Committee on Immunization Practices.

It is believed that the first person is confirmed to have a second infection;

That is, he "was infected twice" (reinfected) with the Coronavirus, and he is from Hong Kong (33 years old), and he did not show symptoms either;

But it harbored enough viruses to infect others.

Dr Maldonado said that the vaccinated people who have a high viral load;

But they have no symptoms, "They will in fact be, in some ways, a worse spreader - of the Coronavirus - because they may be under a false sense of safety."

Therefore, continuing to wear a mask after receiving the Corona vaccination is necessary, to protect yourself and others.
