According to a study from Israel, the vaccine from Biontech / Pfizer vaccine is already highly effective against corona after the first vaccination.
As the Sheba Hospital near Tel Aviv announced, there were 85 percent fewer symptomatic infections among 7,214 clinic employees 15 to 28 days after the first dose.
The number of all infections, including asymptomatic ones, fell by 75.
The results were published on Friday in the medical journal "The Lancet"
"This supports the UK government's decision to start vaccinating its citizens with a single dose," said the hospital's deputy general manager, Arnon Afek, according to the statement.
Great Britain had extended the interval between the first and the second vaccine dose required for full immune protection to twelve weeks in order to be able to immunize more people faster.
Pfizer recommends an interval of three to four weeks.
Previous analyzes had shown the vaccine to be very effective in preventing symptomatic infections one week after the second vaccination.
According to a recent survey by the health insurance company Clalit, it was 94 percent.
