Omicron: good signs that Sinopharm and Sinovac shots fend off severe illness, WHO expert says

China’s widely used Sinopharm and Sinovac Covid-19 vaccines will give some protection against severe illness, hospitalisation and death from the Omicron variant despite declines in protective antibodies, a WHO official said on Tuesday.

The assessment from World Health Organization incident manager Abdi Mahamud came just days after several preliminary laboratory studies indicated that three doses of Sinovac did not produce enough antibodies to prevent infection from the new variant.
