Biontech vaccination lowers infection risk by 85 percent – Science

New data from the UK shows that Biontech and Pfizer’s vaccine also prevents coronavirus infection.

According to an analysis of British data, the vaccine from Biontech and Pfizer also prevents infection with the coronavirus. The risk of infection drops by around 70 percent after the first of the two planned doses and by around 85 percent after the second, the British health authority Public Health England announced on Monday, citing preliminary data that has not yet been verified by independent experts.

“This suggests that the vaccine could also help stop the transmission of the virus because you cannot pass the virus on if you are not infected,” the statement said. The reported values ​​go back to the “Siren” study, in which questionnaires on symptoms, smears and blood serum samples are regularly analyzed for a group of around 40,000 employees from the health sector.

If further analyzes confirm that the vaccines currently used significantly reduce the transmission of the virus, the pandemic could be effectively slowed down with the ongoing vaccination campaigns – and the faster the faster large parts of the population are vaccinated.

Effects similar in the case of mutation

The analysis, which includes various British data sets, also shows that the Biontech / Pfizer vaccine in variant B.1.1.7 apparently works just as well as the previously predominant virus type.

For people over 80 years of age, the evaluation showed that people vaccinated with the first dose had a 57 percent lower risk of Covid-19 than non-vaccinated people, and after the second dose the risk of disease was around 85 percent lower. For at least 14 days after vaccination of the first dose, the risk of death was reduced by more than half for those over 80 years of age compared to non-vaccinated seniors of this age.

Across all age groups, the preliminary data therefore indicate a more than 75 percent lower risk of vaccinated people for hospital admission or a fatal outcome compared to non-vaccinated people.

Data from almost 150,000 people

It should be noted that all values ​​are preliminary data that have not yet been checked by independent experts and published in a specialist journal. Initially, nothing was known about possible restrictions.

Among other things, the evaluation included data from more than 148,000 people over the age of 70 who tested positive for Sars-CoV-2 between December 8 and February 12. The course of the disease was compared between those who had already received a vaccination and those who had not been vaccinated. Data on hospital admissions and deaths were also included.

The UK government feels the results have strengthened its vaccination strategy, which aims to ensure that many people are given their first vaccination as soon as possible. The second dose will not be given for up to twelve weeks. “The current vaccination strategy will save more lives by ensuring that more people receive protection from serious illness after the first dose,” said Health Secretary Matt Hancock, according to the statement.

In total, around 17.5 million people in the UK have been vaccinated with a first dose. Only around 615,000 people received a second dose.
