With some countries beginning the coronavirus vaccination phase, the bigger question remains: will generalization prevent the spread of the infection?
The answer to this question is not so easy, because one of the effects of producing a vaccine so quickly is that it can be produced with many unknown things, which we must wait to discover.
“In theory, the vaccine should stop the infection as well as the transmission and spread,” said Dr. Purvey Barrick, an immunologist with the nonprofit Allergy and Asthma Network and a co-investigator on the Pfizer vaccine trials, according to the Five Thirty Eight website.
But Barrick noted that despite this, we still don’t know if this applies to “Covid-19” vaccines, because the clinical trials were short, so the scientists focused on getting answers to certain questions, such as effectiveness. of the vaccine, and if it was not safe and they got these answers that were enough to produce an urgent vaccine.
But answering these questions quickly came at the cost of answering other questions, such as whether vaccinated people could still transmit the virus.
“With other vaccines, it takes years to analyze the data to find out,” says Barrick.
That’s why the experts are cautious, balancing your enthusiasm and comfort with caution so you can’t forget about the Corona procedures and get back to normal. They need more time to learn the “nature of life” after vaccination, according to the “Five Thirty Eight” website.
Deepta Bhattacharya, a professor of immunobiology at the University of Arizona, said that the theory of spreading the virus even after vaccination is scientifically a possibility.
He added: “It will not surprise me to learn that a person protected from the symptoms of” Covid-19 “, such as those who receive the vaccine, can spread the virus, because there is a biological mechanism for this to happen.
Bhattacharya explained the process: “The virus enters the upper respiratory tract, either through the nose or the throat. These are protected by a mucous layer. Therefore, this mucous layer is good for slowing things down.
“But even if the vaccine has trained your immune cells to get rid of the ‘Covid-19’ viruses that are being detected, they may not be able to neutralize the ones in your nose, on the other side of the mucosal barriers. These corona virus cells won’t harm you, but they can still reproduce, go out into the world, and infect others in the community. “
For its part, Barrick told the site that the examples before us today are vaccines that protect the person who receives them, far more than they protect society as a whole.
But even if the vaccine does not guarantee the protection of the entire community, it will certainly reduce the spread of the virus, because the effectiveness of the new vaccines is enormous, according to doctors.
“If you have a vaccine that is 95 percent effective, this will definitely lead to a reduction in the rate of transmission of the virus around the world,” Bhattacharya said. “This is indisputable, but we want to know to what extent the virus transmission rate will decrease.”
