A Covid-19 vaccine being developed by Pfizer and Germany’s BioNTech has been found to be more than 90 per cent effective, in a major breakthrough that could make the shot available for use by the end of the year if drug authorities give it the green light.
The finding was the result of the first independent analysis of any Covid-19 vaccine in phase 3 trials — the final stage before commercial licensing. The study found that 94 participants who received the two-dose vaccine were protected against the disease 28 days after their first inoculation.
“To me, this is the best possible outcome,” Ugur Sahin, co-founder and chief executive of BioNTech told the Financial Times, while Pfizer boss Albert Bourla said it was “a great day for science and humanity”.
“The risk-benefit profile is in clear favour of benefit, it fulfils all the criteria to be processed fast,” Mr Sahin added. He said that the drug would be submitted to authorities for emergency approval within a matter of weeks.
