U.S. plans to use real world and trial data to determine when vaccines need to be updated
17 March 2021 - U.S. officials plan to use data gathered from people who have already been vaccinated against COVID-19 as well as data from ongoing clinical trials to determine when and whether current vaccines need to be updated to address viral variants.
Peter Marks, director of the Food and Drug Administration’s Center for Biologics Evaluation and Research, said in a hearing on Wednesday that his agency has already started getting data on vaccine safety from surveillance systems.
