Potential First Working Vaccine Found for COVID-19
Pharmaceutical giants Pfizer and BioNTech have announced the development of a vaccine that is 90% effective in preventing Coronavirus. Describing it as a "great day for science and humanity", Pfizer chief executive Dr Albert Bourla has expressed his confidence in getting even closer to a breakthrough that could resolve the global health crisis.
Amongst the 43,538 participants that took part in the study, analysis of the cases evidenced a 90% rate of protection from the virus, with only 94 actually developing the virus after 28 days. No additional health concerns were found following the vaccine.
This is the first vaccine of a few to provide results whilst in Stage 3 of testing. Looking towards future global supply, Pfizer and BioNTech have said they will be able to roll out 50 million doses by the end of the year, with a projected 1.3 billion by the end of 2021.
"It is a relief... there is a long long way to go before vaccines will start to make a real difference, but this feels to me like a watershed moment" added Professor Peter Horby, from the University of Oxford.
