The COVID-19 vaccine may not provide you with comprehensive protection immediately

According to the Centers for Disease Control and Prevention (CDC), Pfizer and Moderna vaccines are injected in two doses-the first injection begins to enhance protection, while the second injection requires the greatest degree of protection against the coronavirus.

The first shot is Proved to be very effectiveDr. Iahn Gonsenhauser, chief quality and patient safety officer at Wexner Medical Center, told CNET. He said that the second dose can enhance the protective effect and prolong the immune life.

Even if you are vaccinated, you can still spread COVID-19

Since both the coronavirus and COVID-19 vaccines are new, there is not enough evidence at this point to know whether people can still carry the coronavirus pathogen and spread it to others without being infected by themselves.

Gonsenhauser told CNET: “This gives the virus enough time to grow in the respiratory tract and spread the infection to other people. With the help of the vaccine, the human body is fighting its own infection.”

There is a lack of data on whether a vaccinated person can spread the virus after infection, and a person may be Asymptomatic carrier, He added.

Gonsenhauser said: “Although the vaccine is very effective, there is still a small chance (5% to 10%) that someone will be infected after being vaccinated.” However, as scientists and doctors learn more about the vaccine’s effects on COVID-19 Role, may get more data.

The CDC said that until experts fully understand the protection provided by the COVID-19 vaccine, it is important to continue to wear masks and comply with social distancing agreements. This can help prevent the coronavirus from spreading among the population until more people are vaccinated with the coronavirus.

Dr. Michael Osterholm, director of the Center for Infectious Disease Research and Policy, said on a CBS radio affiliate on December 14 that wearing a mask “increased protection against vaccines.” The CDC stated that wearing a mask and vaccinating together will provide the best protection for acquiring and spreading COVID-19.

About reinfection and “natural” immunity remain unknown

The CDC said: “The immune response to COVID-19, including the duration of immunity is not yet clear.”

More research is needed to determine the likelihood of your re-infection, and the CDC stated that “it’s not clear what antibody level is needed to prevent re-infection.”

The human body’s defense against the virus seems to disappear relatively quickly during and after infection, which is difficult to achieve Herd immunity Dr. William Haseltine, a former professor at Harvard Medical School, said that for a long period of time, he was famous for his research on the human genome and HIV/AIDS.

“The bigger problem is that someone is re-infected by the same COVID-19 variant. Although they are not sick, they can still infect others. You may be infected twice, the second time asymptomatic, and still carry and spread to the University of Pittsburgh. Professor of Pediatrics John V. Williams said.

So far, almost no Coronavirus reinfection. In fact, according to the CDC, reported cases of re-infection with COVID-19 are still very few. However, according to a report by Scientific American, if COVID-19 is the same as other types of coronaviruses, such as the common cold, reinfection will become more common over time.

People who have not been vaccinated may think it is okay to stop wearing a mask

Gunsenhauser said of social behavior: “If people no longer wear masks after vaccination, other unvaccinated people may start to think that masks are no longer needed.” If those who have not been vaccinated become infected With this virus, they can spread faster without wearing a mask.

How long must I wear the mask and social distance? What needs to happen?

The CDC said there is not enough information to determine if or when most people can safely stop wearing masks and avoid close contact with others to help prevent the spread of the coronavirus, but it may come down to numbers.

When enough observable changes occur, for example, the number of cases drops, and the threat to the community drops sharply. When this happens, medical experts can re-determine whether a mask is required. However, it may not be realized until 2021.

Gonsenhauser said: “After getting enough vaccines, we need to see a sharp drop in the number of new cases per 100,000 people.”
