Combating coronavirus: Potential Covid-19 vaccine from China shows promise in animal tests

More than 100 potential Covid-19 vaccines are in various stages of development around the world.. A potential Covid-19 vaccine being developed by Chinese researchers showed promise in trials in monkeys, triggering antibodies and raising no safety issues, researchers said, and a human trial with more than 1,000 participants is under way.. The vaccine candidate, called BBIBP-CorV, induced high-level neutralising antibodies that can block the virus from infecting cells in monkeys, rats, guinea pigs and rabbits, researchers said in a paper published in online by the medical journal Cell on Saturday.. " the results support the further evaluation of BBIBP-CorV in a clinical trial," researchers said in the paper.. BBIBP-CorV, developed by Beijing Institute of Biological Products affiliated to state-owned China National Pharmaceutical Group (Sinopharm), is among five candidates China is testing in humans.. Among front runners currently in human trials are being developed by AstraZeneca, Pfizer, BioNtech, Johnson & Johnson, Merck, Moderna, Sanofi and China's CanSino Biologics.. As well as appearing safe and able to generate an immune response in animals, BBIBP-CorV did not appear to trigger antibodies that could boost the infection - a phenomenon known as antibody-dependent enhancement (ADE)- the researchers said, although this does not necessarily guarantee
