A new study released Tuesday from the New England Journal of Medicine shows antibodies from the Moderna vaccine last at least six months after the second dose.

Thirty-three adults participated in Moderna’s ongoing study and despite antibodies remaining high in all ages, researchers said antibodies among those in older age groups were lower than younger adults.

“Ongoing studies are monitoring immune responses beyond six months, as well as determining the effect of a booster dose to extend the duration and breadth of activity against emerging viral variants,” the study said.
