Covid-19: Pfizer and BioNTech vaccine offers 90% protection
According to a preliminary analysis, the vaccine developed by Pfizer and BioNTech can prevent more than 90% of people from getting Covid-19. However, the data presented is not the final analysis as it is based on only the first 94 volunteers to develop Covid-19 so the precise effectiveness of the vaccine may change when the full results are analysed.
The companies stated they would be able to supply 50 million doses by the end of this year and around 1.3 billion by the end of 2021. Each person needs two doses.
Dr Albert Bourla, the chairman of Pfizer, 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."
