A randomized controlled trial of two inactivated (vero cell) COVID-19 vaccines made in China finds a vaccine efficacy of 73% in one and 78% in the other, according to a study yesterday in
JAMA.
The whole-virus inactivated vaccines were developed with strains of the virus taken from patients in Wuhan, China.
The phase 3 trial included approximately 40,000 adults in the United Arab Emirates and Bahrain who were assigned to receive either a vaccine (WIV04 or HB02) or an alum-only injection. Both vaccines are two-dose inactivated injections, and the primary end point of the trial was symptomatic COVID-19 at least 14 days after the second injection.
