China's top disease control official has said the country is formally considering mixing COVID-19 vaccines as a way of further boosting vaccine efficacy, APA reports quoting Anadolu Agency.
Available data shows Chinese vaccines lag behind others including Pfizer and Moderna in terms of efficacy, but require less stringent temperature controls during storage.
Giving people doses of different vaccines is one way to improve vaccines that "don't have very high rates of protection", Gao Fu, the director of the Chinese Centers for Disease Control and Prevention, said on Saturday, without specifying whether he was referring to foreign or domestic vaccines
"Inoculation using vaccines of different technical lines is being considered," Gao told a conference in the Chinese city of Chengdu.
Gao said that taking steps to "optimise" the vaccine process including changing the number of doses and the length of time between doses was a "definite" solution to efficacy issues.
