The vaccine from Pfizer & BioNTech limits the transmission of the coronavirus


Research conducted in Israel shows that the vaccine from Pfizer and BioNTech is not only effective in protecting against Covid-19, but also significantly reduces the transmission of coronavirus by the infected – writes “Der Spiegel” on Sunday.

In the light of the yet unpublished data that the German weekly has found, “vaccine German company BioNTech and her American partner Pfizera seems to be largely preventable coronawirusa, reduces its transmission by up to 89.4 percent. “

This news may be decisive in predicting the further development of the pandemic

– writes “Der Spiegel”, emphasizing that the research was carried out jointly by German experts and the Israeli health ministry.

About one third of the population has already been vaccinated in Israel

In Israel, about a third of the population has already been vaccinated. Therefore, for the first time, it was possible to observe on a large scale how the vaccine works and how it affects the epidemiological situation. Overall, the study included data from around 1.7 million vaccinated people, we read.

The results of this research were awaited with great anticipation. Clinical trials that preceded the approval of the vaccine only verified its effectiveness in preventing Covid-19. Whether vaccinated people could be carriers of the virus has remained unclear until now.

The expectations were quite modest. Even the president of BioNTech, Ugur Sahin, assumed that a vaccine developed jointly with Pfizer would be able to prevent infection at most 60 percent.

– piss “Der Spiegel”.

Vaccinated people protect not only themselves but also others

The result turned out to be surprisingly positive.

While only 1,842 Sars-CoV-2 infections per 100,000 occurred in the double vaccinated group, which corresponds to an incidence rate of 11.5 per so-called man-days, 76,797 infections occurred in the unvaccinated control group, which corresponds to an incidence rate of 114.4, which is about ten times higher

– writes the German weekly.

Data from Israel clearly indicate a decline in infections in a growing part of the population. This proves that vaccinated people protect not only themselves but others. Importantly, the British variant of the B.1.1.7 coronavirus was already the dominant variant during the study, covering 81%. cases.

The results of the research have not yet been published in a scientific journal

The research cited by “Der Spiegel” has not yet been published in a scientific journal. Therefore, the detailed data is not yet commented on by Pfizer and BioNTech. The 22-page document has already been partially released in Israel.

If the vaccine were to protect us only against the severe form of Covid-19, in the worst case the vaccinated would become a mass of asymptomatically infected, who, convinced that they were not dangerous, would infect others

– piss “Der Spiegel”.

On the other hand, if almost 90 percent. vaccinees are not actually carriers of Sars-CoV-2, it will be much easier to control the pandemic in the next few months, and contact restrictions may also be eased much earlier

– he adds.
