    Serum Institute of India’s CEO Adar Poonawalla told India Today that Oxford-AstraZeneca’s Covishield vaccine’s efficacy rises to 90% if the doses are given 2.5-3 months apart. A Lancet study had earlier said that the vaccine had 70% efficacy with a month’s gap between doses. “A group was administered doses with higher gap…and they found the efficacy was 90%,” Poonawalla said.
