A single dose of the Pfizer vaccine delivers around 65 per cent protection against coronavirus in both older people and young adults, provisional results have found.
The jab begins to become effective in just two weeks, according to The Sun, and after the second dose people’s protection rises to 84 percent.
It has been reported the Oxford vaccine is likely to return similar results.
The first dose reduces symptomatic infection risk by 65 percent in younger adults and 64 percent in over-80s, according to the newspaper.
After the second dose, this increases to between 79 and 84 percent dependent on age.
Clinical trials suggested there would be 95 percent protection. The data is expected to be released in the coming days.
