A study of vaccinated people raises high hopes, but the data have not yet been published. We answer the open questions.
The vaccine from Pfizer / Biontech should not only protect very effectively against Covid disease, but also almost 90 percent against infection with the Sars-CoV-2 coronavirus. This news from Israel spread at lightning speed over the weekend, but the study on which the reports are based has not yet been officially published, let alone assessed by independent experts.
But if the rumored basic statement, namely that vaccination can actually also massively reduce infections, only approximately applies, this would be a reason for optimism. Because if you are infected much less often after the vaccination, the virus can also be transmitted or passed on much worse. Vaccinations could make a significant contribution to the fact that herd immunity may soon be foreseeable would, sothat the virus can no longer spread in the population.
