New efficacy data from Brazil on Sinovac's COVID-19 vaccine, for which there are now four widely different success rates, raised more questions than answers, as many developing countries pin their hopes on the CoronaVac to end the pandemic.
More rampant infections in Brazil than in other trial sites and its study design to focus on medical workers could have led to more mild infections in trials, thus lowering efficacy data, a person familiar with the matter said. Fake positive results delivered by high-sensitivity COVID-19 tests may have also worsened the reading, the person added.Experts say it is difficult to interpret the efficacy results as the full datasets are not out.
Jerome Kim, head of vaccine research group International Vaccine Institute said it would be possible to combine data from multiple studies with varied trial designs but it could involve additional statistical manipulation.
Another controversy popping out of their imaginative minds? Then there are others to pick it up? Hahahahaha
