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.
