IT must now be said. The skeptics and Sinovac naysayers have been right all along. The Chinese vaccines against Covid-19 — be they Sinovac or Sinopharm — have low effectiveness rate and can reasonably be refused by prospective vaccinees on the grounds of efficacy and safety.

Gao Fu, the director of the China Center for Disease Control and Prevention (CDC), says the effectiveness of the Chinese vaccines is low, and the government is considering mixing them to get a boost.
