Antibodies against the novel coronavirus declined rapidly in the British population during the summer, a study found, suggesting protection after infection may not be long lasting and raising the prospect of waning immunity in the community.

BioSpace reviews some of the more interesting recently published scientific studies, including whether the Covid-19 virus relieve pain.

Results 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.
