The Pfizer vaccine also reduces the risk of infection without symptoms

It is a strong indication that the vaccine can also prevent many new infections.

In recent months, it has already been widely proven that the Corona vaccines currently being used in our country to combat COVID-19, among other things, are safe. And it greatly reduces the chance of developing a serious disease. However, it remained unclear whether these vaccines also reduce the risk of developing asymptomatic infections. That may not seem relevant. But appearances can be deceiving. Studies show that a large percentage of infections are caused by people without symptoms. These people are not aware that they are carrying the virus, are not subject to quarantine and can infect quite a few people. In order to limit the spread of the virus as much as possible, you actually need a vaccine that also protects against asymptomatic COVID-19. Pfizer vaccine like this, researchers now conclude with caution this study (Which, by the way, has yet to undergo peer review.)

The researchers base their conclusions on a survey of British hospital staff. The hospital staff was divided into three groups: a group that had not been vaccinated, a group that had been vaccinated at least 12 days before (the virus is believed to protect against symptoms of COVID-19 after 12 days) and a group that was vaccinated. He was vaccinated less than 12 days ago. After that, all concerned hospital staff – although there were no complaints – underwent multiple PCR tests over a two-week period to determine if they were carrying the virus.

The unvaccinated group underwent 3,252 PCR tests over a two-week period, of which 26 were positive (0.8 percent). In the group vaccinated at least 12 days before, 1989 tests were conducted, 4 of them (or 0.2 percent) were positive. In the group vaccinated less than 12 days ago, 3,535 tests were performed during the same period, and 13 were positive (0.37 percent). The results cautiously indicate that the risk of asymptomatic infection among hospital staff vaccinated at least 12 days before is four times lower. And for hospital staff who were vaccinated less than 12 days ago, the risk of developing an asymptomatic infection was halved.

Promising news
Researcher Mike Wickes said: “This is great news – the Pfizer vaccine not only protects against SARS-CoV-2, but also helps prevent infection, thus reducing the chance of transmitting the virus to others.” “This news is very welcome as we try to figure out a way out of this epidemic. But we must remember that the vaccine does not provide complete protection for everyone. So we still have to keep our distance, wear face masks, wash our hands and get tested regularly so that the epidemic is brought under control properly.” Best “.

The Zionist entity
Research is consistent with a study It was released earlier this week based on research in Israel. Not only did the study discover that the Pfizer vaccine prevented COVID-19, but it also showed that the vaccine also protected against infection asymptomatically, especially after a second administration. But in this new research, scientists have shown that the vaccine does so even after a single dose. Professor Lawrence Young of Warwick Medical School concludes that “these studies are very promising because they indicate that vaccines prevent the spread of the virus.”

Professor Jonathan Ball, a molecular virologist at the University of Nottingham who was not involved in the study among British hospital staff, is also excited. “Such a decrease in the number of infections after a single dose of Pfizer vaccine is very impressive and shows that vaccines are really a way out of the current restrictions and into a brighter future.”

At the same time, more research is still badly needed, most experts agree. The British study is not very extensive and, moreover, only concerns the hospital staff. Many hospital employees had previously been exposed to corona, and therefore they had an immune response before vaccination that may have enhanced the effect of the vaccine. So it seems a good idea to repeat the study among a larger and more diverse group of people in the future, says Dr. Simon Clark, a cellular microbiologist at the University of Reading and was not involved in the study. “Additionally, it is also important to remember that these results cannot be translated directly to other vaccines.” Only applicable to Pfizer. Moreover, even with a Pfizer vaccine, it remains unclear how long protection against symptomatic (a) infections will last.

hoop
But while awaiting this follow-up research, we can definitely have high hopes based on this initial study. Hope vaccines really make a difference. Dr Peter English, former chair of the Medical Committee for Public Health at the British Medical Association also said: “These preliminary data are not sufficient to ensure that vaccines prevent infection and transmission – and thus contribute to herd immunity – but they strongly suggest this.” She did not participate in the study. “This gives us hope that vaccinations will ensure – in the end – that there is less or even no need for social distancing, mouth masks and other behavioral measures.”

If the results also remain valid during the follow-up studies, vaccines will actually lead to a significant reduction in virus transmission and thus new infections. It’s great news. Dr Andrew Friedman of Cardiff University School of Medicine says it takes people to get vaccinated. “(The study, editor) emphasizes the importance of everyone being offered the vaccine and accepting it to protect themselves as well as others in the community.”
