Pfizer early trials show vaccine 90% effective in preventing Covid-19

US pharmaceutical giant Pfizer and German biotech firm BioNTech said their coronavirus vaccine was more than 90% effective in preventing Covid-19, as per early trial data.

American pharmaceutical Pfizer Inc and its German partner BioNTech SE on Monday said that early data has shown that their Covid-19 vaccine is more than 90 per cent effective in preventing Covid-19.
Pfizer and German partner BioNTech SE are the first drugmakers to show successful data from a large-scale clinical trial of a coronavirus vaccine.
The shots made by Pfizer and its German partner BioNTech are among 10 possible vaccine candidates in late-stage testing around the world — four of them so far in huge studies in the US.
According to reports, Pfizer Inc has also indicated that is on track later this month to file an emergency use application with US regulators.
