BRITISH scientists thought to be leading the global race to develop a COVID-19 vaccine are close to a major breakthrough according to reports. The life-saving antibody treatment developed by Oxford University has been hailed as potentially vital for the elderly and vulnerable, whose bodies may not respond well to a vaccine. Millions of doses of the treatment is already being manufactured by pharmaceutical giant AstraZeneca in the expectation that it will work. The vaccine, named ChAdOx1 nCoV-19, is made from a weakened version of the common cold virus, which causes infections in chimpanzees. The virus has been manipulated to not cause harm to humans, but contains part of COVID-19 so to trigger the body’s immune response to the virus’s spike proteins, which it uses to enter human cells and multiply. A separate project to create an antibody treatment for those especially vulnerable to COVID-19 is also being developed, with the team confident it will prove successful. Testing for the..
