Pharmaceutical giant on board to make two billion doses within 12 months for COVID-19 vaccine that could be in use by the end of the year
Samples from the coronavirus vaccine trials are handled inside the Oxford Vaccine Group laboratory in Oxford, England, on June 25, 2020.Researchers at Oxford University have released promising test results for a COVID-19 vaccine, which uses a novel technology based on a cold virus found in chimps, and said the drug could be in use by the end of the year.
He added that the vaccine is undergoing further tests on more than 40,000 people in Britain, the U.S., South Africa and Brazil. Results from those tests are expected this fall and if successful, the vaccine could be approved for limited use by December. British Prime Minister Boris Johnson also applauded the Oxford group on Monday and struck a note of warning. “It may be that the vaccine is going to come riding over the hill like the cavalry. But we just can’t count on it right now,” he said.
Once injected as a vaccine, it primes the body’s immune system to recognize and attack COVID-19. The central mechanism – known as ChAdOx – has already served as a platform for vaccines for Ebola and other coronavirus diseases such as Middle East respiratory syndrome. “So we can’t say just by looking at the immune responses whether this is going to protect people or not. The only way we are going to find out is by doing the large phase trial and waiting for people to be infected as part of that trial before we know if the vaccine can work.”Dr. Hill said the world will need more than one vaccine and he called on researchers to work together.
