What the Study Found (In Plain English)

Published in Vaccine (2023), this phase iii randomized trial evaluating human clinical outcomes investigated: PREVENT-19, the pivotal phase 3 trial of the Novavax adjuvanted, recombinant spike protein COVID-19 vaccine (NVX-CoV2373), demonstrated that the vaccine was well tolerated and efficacious (vaccine efficacy, VE = 90%) for the prevention of symptomatic COVID-19. Key clinical takeaway: Among an expanded efficacy population, also identified post hoc, which included COVID-19-associated hospitalizations without a requirement for diagnostic polymerase chain reaction testing performed at the study central laboratory, 12 total hospitalizations were identified, 0 among...

Study Limitations & Caveats Before You Act

Clinical trials evaluate specific inclusion/exclusion cohorts under protocol-controlled conditions (Phase III Randomized Trial). Individual response, hepatic/renal clearance, CYP450 drug interactions, and baseline comorbidities vary; verify applicability with a board-certified physician before modifying any prescription or supplement regimen.
