Moderna covid vaccine: Early study shows it working in older adults
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.The study was an extension of Moderna's Phase I safety trial, first conducted in individuals aged 18-55.
