Top Chinese Official Admits Low Effectiveness Of China's Vaccines, Mulls A Vaccine CocktailSinovac

China's Centre for Disease Control Director Gao Fu admitted in a press conference that Chinese vaccines do not have high protection rates and hence they might have to be mixed to provide a boost.

“It's now under formal consideration whether we should use different vaccines from different technical lines for the immunisation process,” the official was quoted as saying by the Associated Press.

For example, the Covid-19 vaccine made by Chinese developer Sinovac has shown a meagre prevention rate of 50.4 per cent in terms of preventing symptomatic infections. Moreover, Gao even hinted at considering the advantages of the m-RNA vaccines, though he had himself raised concerns over its safety back in December.

He claimed that it should be utilised carefully and not ignored merely because numerous types of vaccines are already available. Beijing has supplied several of its indigenously-developed vaccines across the world and has also prohibited the use of any international vaccine in China.

Sequential immunisation along with mixture of vaccines are said to shoot up their effectiveness. Hence, certain researchers in Britain are also deliberating upon possibly combining the Pfizer and AstraZeneca vaccines to avail better returns.
