Durability of Response after Ad26. COV2. S Vaccination In this study, investigators
measured immune responses in 20 participants who had received either one or two doses
of the Ad26. COV2. S vaccine and in 5 who had received placebo. A high level of
neutralizing antibodies against SARS-CoV-2 was maintained for at least 8 months after
single-dose injection, with a median decrease by a factor of 1.8 in the titer.
