Pfizer and BioNTech have released results that show that their coronavirus vaccine is 95 per cent effective and said that they would submit their Covid-19 vaccine for US and EU emergency approval “within days”,

The results showed that in global phase three trials involving more than 43,000 people, 170 were observed to have contracted coronavirus, out of which 162 had been given a placebo,

Just eight of those who had received two shots of the BioNTech-Pfizer vaccine developed the disease and only one became seriously ill, while nine of the placebo group developed severe Covid-19.

“The study results mark an important step in this historic eight-month journey to bring forward a vaccine capable of helping to end this devastating pandemic,” said Albert Bourla, Pfizer chief executive, adding that the companies were sharing the data with regulators around the world
