Brief Summary

This is a Phase 4, post-market US study, evaluating the efficacy and safety of a singledose of the NVX-CoV2705 Omicron JN.1 COVID-19 vaccine. Approximately 6,500 healthy adultsaged 50 to under 65 will be randomized to receive either the vaccine or a placebo, withfollow-up for 180 days.

Detailed Description

This is a Phase 4, multicenter, randomized, double-blind, placebo-controlled,

JN.1 subvariant severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) recombinant
(r) spike (S) protein nanoparticle vaccine (SARS-CoV-2 rS) adjuvanted with Matrix-M
(NVX-CoV2705) in adults 50 to < 65 years of age who are not considered to be at high risk
of severe coronavirus disease 2019 (COVID-19). This study will be conducted in the United

(normal saline) on Day 0 and remain on study for efficacy and safety data collection
through Day 180/end of study (EoS).
