A Covid-19 booster shot produced by China's Sinopharm had "significantly lower" neutralising activity against the Omicron variant, Chinese researchers said in a paper, although they added the vaccine's efficacy against Omicron remained unclear.
The study - conducted by researchers from Shanghai Jiao Tong University and a Shanghai-based lab specializing in respiratory infectious diseases - compared the activity of Sinopharm's booster vaccine against an older coronavirus strainfrom Wuhan.
The neutralising antibody activity of a Sinopharm BBIBP-CorV booster against Omicron showed a 20.1-fold reduction, compared with its activity against a Wuhan strain, according to the paper published on Saturday.
Sinopharm did not immediately respond to a request for comment.
