Chinese COVID-19 vaccines, including those from Sinovac Biotech (NASDAQ:SVA) and Sinopharm Group (OTCPK:SHTDF) (OTCPK:SHTDY), are 69% effective in the prevention of infection among close contacts, according to a study involving more than 100 patients with the Delta variant.
Previously, an Israeli study indicated that with the spread of the Delta variant and relaxation of social restrictions, the effectiveness of the Pfizer (NYSE:PFE)/ BioNTech (NASDAQ:BNTX) COVID-19 vaccine dropped to 64% in preventing both infection and symptomatic disease.
