Pfizer and BioNTech on Monday said that their jointly developed vaccine was more than 90% effective in preventing coronavirus, in what comes as a major development in the fight against the pandemic that has killed over a million people.
“Today is a great day for science and humanity. The first set of results from our Phase 3 COVID-19 vaccine trial provides the initial evidence of our vaccine’s ability to prevent COVID-19,” said Dr Albert Bourla, Pfizer’s chief executive in a statement.
According to initial findings, protection in patients was achieved seven days after the second of two doses, and 28 days after the first.
“The first set of results from our Phase 3 Covid-19 vaccine trial provides the initial evidence of our vaccine’s ability to prevent Covid-19,” Dr Bourla said.
“We are a significant step closer to providing people around the world with a much-needed breakthrough to help bring an end to this global health crisis,” he said.
“We are reaching this critical milestone in our vaccine development program at a time when the world needs it most.”
