One dose of Pfizer / BioNTech or AstraZeneca corona vaccine reduces infections within the family by nearly half, and the UK health service PHE reports based on research.
According to the study, people who become infected with the virus three weeks after a first shot are 38 to 49 percent less likely to pass the virus on to other family members than people who were not vaccinated.
This applies regardless of the age of the infected person or his or her family members.
“This is fantastic news. We already knew that vaccines save lives, and this study, the most complete in real-life conditions, shows that they also reduce the transmission of this deadly virus,” said UK Health Minister Matt Hancock…
The study followed 57,000 people from 24,000 families where a vaccinated person tested positive and compared the infection rates with nearly one million contacts between people who have not been vaccinated.
