The Omicron variant of the coronavirus evades immunity offered by an inactivated Covid-19 vaccine developed by Sinopharm, a lab study has found.⁠

Results showed the antibody levels of people vaccinated with Sinopharm’s vaccine dropped significantly against Omicron compared with the ancestral, or older, strain and, of the total 13 participants, only three people could be found to produce detectable antibodies that could block the Omicron strain of the virus from entering cells, a process known as “neutralising”.⁠

A drop in effectiveness against Omicron was observed in all six vaccines tested, but participants vaccinated with Moderna, Pfizer and AstraZeneca vaccines displayed higher levels of neutralising antibodies against the ancestral strain and, after a 33-44-fold drop they still had detectable neutralising antibodies against the Omicron variant.⁠

It confirmed a flurry of studies that found the mutations on the receptor-binding domain of the Omicron’s spike protein – the part of the coronavirus that docks on to human cells, initiates infection and targets of most Covid-19 vaccines – led to immunity escape against available vaccines, including those produced by Moderna and Pfizer.⁠
