A Covid-19 vaccine developed by drug giant Pfizer and German biotechnology firm BioNTech, has been found to be more than 90 per cent effective.
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. Out of the 43,000 trial participants, the small number who were infected enabled the independent evaluators to calculate the effectiveness after two doses.
“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”.
“I would say it’s a historical moment. Something like this has never happened before. First of all, the world was faced with such a terrible situation, the pandemic, and being able in such a short time to go through what usually takes many years,” Kathrin Jansen, head of vaccine research and development at Pfizer, said in an interview. “Hearing that at the interim analysis we are over 90 percent effective — it was almost stunning to hear.”
Pfizer shares jumped almost 15 per cent in pre-market trading in New York, while Nasdaq-listed BioNTech rose 25 per cent.

@CMO_England: Preliminary news that the Pfizer/BioNTech vaccine is effective demonstrates the power of science against COVID. We must see the final safety and efficacy data, but it is very encouraging. It is essential we continue to suppress COVID, but it is a reason for optimism for 2021.
@piersmorgan: News of a potential vaccine with 90% efficacy is incredibly exciting. But it makes it even more important for us all to obey the lockdown rules in the meantime. Let’s stop as many people dying as possible before the Pfizer cavalry comes.
@politvidchannel: Pfizer waited until after the election to tell us about the good vaccine news and they called Biden first.
