AstraZeneca expects updated COVID-19 vaccine by autumn
Associated PressLONDON — AstraZeneca said Thursday it expects to have a new version of its COVID-19 vaccine ready for use by this autumn as drugmakers respond to concerns about emerging variants of the disease that may be more transmissible or resistant to existing vaccines. The comments came as CEO Pascal Soriot defended the company’s efforts to develop and ramp up production of the shot amid criticism from the European Union and a preliminary study that raised concerns about the vaccine’s ability to combat a variant of COVID-19 first discovered in South Africa. While rollout of the vaccine hasn’t been perfect, regulators in a number of countries have found the vaccine to be safe and effective, and AstraZeneca will produce 100 million doses this month, Soriot said. “One hundred million doses in February means 100 million vaccinations, which means hundreds of thousands of severe infections that are avoided, and it also means thousands of deaths that are avoided,” Soriot said.
