China considers mixing vaccine to boost efficacy

Effectiveness of its vaccines ‘not high’

China is considering the mixing of different COVID-19 vaccines to improve the relatively low efficacy of its existing options, a top health expert has told a conference. Authorities have to “consider ways to solve the issue that efficacy rates of existing vaccines are not high”, Chinese media outlet The Paper reported, citing Gao Fu, the head of the Center for Disease Control and Prevention. His comments mark the first time a top Chinese expert has publicly alluded to the relatively low efficacy of the country’s vaccines, as China forges ahead in its mass vaccination campaign and exports its jabs around the world.
