CHINA is formally deliberating mixing their own vaccines with other coronavirus jabs in order to boost their effectiveness, according to the country’s Center for Disease Control and Prevention chief, Gao Fu, although he did not specify if these would include vaccines from Western nations.
“Inoculation using vaccines of different technical lines is being considered,” he said in a conference.
Other possible solutions to improve their vaccines’ efficacy included changing the number of doses and changing the length of time between doses, he said.
“The global protection vaccine protection rate test data are both high and low,” Gao said. “How to improve the protection rate of vaccines is a problem that requires global scientists to consider.”
China had locally manufactured four vaccines which were authorized for use by the public, but clinical data showed homegrown jabs offered less protection than Pfizer and Moderna. However, these vaccines needed less extreme storage temperatures to stay viable.
Despite the admittedly low protection, a key study had previously showed that Sinovac’s CoronaVac shot was capable of reducing the risk of symptomatic and severe Covid infection by half.
China has since shipped millions of doses to other countries, among them the Philippines.
