China's Sinovac Covid-19 vaccine found highly effective in real world study - superadmin - 05-12-2021 JAKARTA (BLOOMBERG) - Sinovac Biotech Ltd's vaccine is wiping out Covid-19 among health workers in Indonesia, an encouraging sign for the dozens of developing countries reliant on the controversial Chinese shot, which performed far worse than Western vaccines in clinical trials. Indonesia tracked 25,374 health workers in capital city Jakarta for 28 days after they received their second dose and found that the vaccine protected 100 per cent of them from death and 96 per cent from hospitalisation as soon as seven days after, said Health Minister Budi Gunadi Sadikin in an interview on Tuesday (May 11). The workers were tracked until late February. Mr Sadikin also said that 94 per cent of the workers had been protected against infection - an extraordinary result that goes beyond what was measured in the shot's numerous clinical trials - though it's unclear if the workers were uniformly screened to detect asymptomatic carriers. "We see a very, very drastic drop," in hospitalisations and deaths among medical workers, Mr Sadikin said. It's not known what strain of the coronavirus Sinovac's shot worked against in Indonesia, but the country has not flagged any major outbreaks driven by variants of concern. The data adds to signs out of Brazil that the Sinovac shot is more effective than it proved in the testing phase, which was beset by divergent efficacy rates and questions over data transparency. Results from its biggest Phase 3 trial in Brazil put the shot known as CoronaVac's efficacy at just above 50 per cent, the lowest among all first-generation Covid-19 vaccines. - More -
