A Chinese Center for Disease Control official admitted that China’s COVID-19 vaccines are ineffective and that they are not ruling out mixing different vaccines to increase their efficacy.
(Sinovac) “don’t have very high protection rates,” said Gao Fu, the director of the China Centers for Disease Control.
Sinovac has been widely distributed across the world and has been used by China as a diplomatic tool.
“It’s now under formal consideration whether we should use different vaccines from different technical lines for the immunization process,” added Gao.
Gao said in earlier interviews that had doubts about the new mRNA technology used in Pfizer and Moderna vaccines within the US.
Pfizer and Moderna vaccines are 97% and 94% effective respectively compared to Sinovac which was found to be only 50% effective in international testing.
Beijing has not yet approved any foreign vaccines for use in China where COVID-19 was said to have originated.
Gao later changed his statement and said Chinese state-run tabloid Global Times that his admission was “a complete misunderstanding.”
“The protection rates of all vaccines in the world are sometimes high and sometimes low. How to improve their efficacy is a question that needs to be considered by scientists around the world,” explained Gao.
