A single dose of Oxford and Astrazeneca vaccine, or Pfizer and Biontech, reduces the chance of needing hospital treatment by more than 80 percent.
This is the result of an analysis by British researchers. Health Secretary Matt Hancock said the result is very encouraging. More than 20 million people in Britain have received the first dose of the anti-covid vaccine in Britain. This means that more than a third of the adult population has been vaccinated.
Hancock said the result of the study could also help explain why the number of hospitalizations in intensive care units, among people over 80 in the UK, has dropped significantly in recent weeks. Health experts in Britain say there is growing evidence that vaccines are working to reduce infections and save lives. The data also show that the Pfizer vaccine, which was administered a month before the Astra zeneka vaccine, leads to an 83 percent reduction in covid deaths.
And they also show that vaccination reduces the risk of people over 70 years developing covid symptoms to about 60 percent, three weeks after the first dose. For British experts meanwhile, the decision to give the astra zeneka vaccine to the elderly is clearly justified while some European countries refuse to give it to over 65-year-olds because the test data were based mainly on the consequences for the elderly. younger adults in age.
