Sinovac shot gives no shield against Omicron: HK study

HONG KONG (Bloomberg): The vaccine made by Sinovac Biotech Ltd, one of the most widely used in the world, doesn’t provide sufficient antibodies to neutralise the Omicron variant, said Hong Kong researchers in initial lab findings that may have sweeping consequences for the millions of people relying on the Chinese shot to protect them against Covid-19.

Among a group of 25 people fully vaccinated with Sinovac’s shot, which is called Coronavac, none showed sufficient antibodies in their blood serum to neutralise the Omicron variant, said a statement from a team of researchers at the University of Hong Kong released late Tuesday night.
