Expert Giorgi Pkhakadze spreads news based on research.
"We have excellent news, the first study in the UK on the Indian mutation of Covid has been conducted, as well as the effectiveness of AstraZeneca and Pfizer have been tested: Pfizer - 1 dose 33.5%, two doses 87.9%; AstraZeneca - 1 dose 33.2%, two doses 59.8% Everything will be fine!
It would be good for the producers of other vaccines to conduct similar independent and high-level studies," Pkhakadze wrote.
