People vaccinated against Covid-19 are likely to transmit the virus. But this risk of transmission would be reduced with just one dose of the Pfizer-BioNTech or AstraZeneca vaccine. This is what the English Public Health Agency (PHE) says.
The study was conducted among 57,000 individuals from 24,000 households where a vaccinated person had tested positive, and compared them to nearly one million contacts of unvaccinated people. The results of the study are final, people infected with the virus three weeks after receiving a dose of the vaccine are 38 to 49% less likely than those who have not been vaccinated to transmit the coronavirus to members of their household , PHE detailed in a press release.
Homes are considered places “high risk” in terms of transmission, and “Similar results could be observed in places with similar transmission risks, such as shared housing and prisons”, underlined the British Public Health Agency.
High protection against the development of symptoms
The English organization also specifies that a single injection of the vaccine makes it possible, after four weeks, to reduce the risk of contracting symptoms by 60 or even 65%. “This is fantastic news. We already knew that vaccines save lives and this study, the most comprehensive conducted in real conditions, also shows that they reduce the transmission of this deadly virus ”British Health Minister Matt Hancock said optimistically.
United Kingdom: the most bereaved country in Europe
With more than 127,000 deaths, the country is engaged in a race against time against the virus. The English have been administering three vaccines since the beginning of December: Pfizer-BioNTech, Moderna and AstraZeneca. According to the latest official figures released on Tuesday, nearly 34 million first doses were injected and at least a quarter of the adult population, or 13.2 million people, received a second dose.
