Moderna COVID-19 vaccine appears safe, shows signs of working in older adults - studyResults from an early safety study of Moderna Inc's coronavirus vaccine candidate in older adults showed that it produced virus-neutralizing antibodies at levels similar to those seen in younger adults, with side effects roughly on par with high-dose flu shots, researchers said on Tuesday. The study, published in the New England Journal of Medicine, offers a more complete picture of the vaccine's safety in older adults, a group at increased risk of severe complications from COVID-19. The findings are reassuring because immunity tends to weaken with age, Dr. Evan Anderson, one of the study's lead researchers from Emory University in Atlanta, said in a phone interview.
