| Description: |
BackgroundSurveillance of COVID-19 vaccine effectiveness (VE) was extensive upon vaccine introduction; however, it declined after the withdrawal of pandemic status in May 2023. Continued monitoring of updated vaccine formulations is needed to ensure the maintenance of VE in the face of evolving viral strains. ObjectiveThe Booster Epidemiological Evaluation of Health, Illness and Vaccine Efficacy (BEEHIVE) study (NCT06065176), a randomized trial with a hybrid design, was developed to assess the real-world VE of the 2023-2024 Pfizer–BioNTech and Novavax COVID-19 vaccine formulations targeting the XBB.1.5 SARS-CoV-2 variant. MethodsThis study was designed to enroll approximately 1500 participants aged ≥18 years from the Salt Lake City, Utah, area who had previously received ≥2 doses of an authorized messenger RNA (mRNA)–based COVID-19 vaccine but had not received a dose of the 2023-2024 formulation. The study used a randomized, hybrid design comprising 2 blinded groups assigned to receive the 2023-2024 formula of either the Novavax COVID-19 vaccine or the Pfizer–BioNTech COVID-19 vaccine and a nonrandomized, observational control group of volunteers who chose not to receive a 2023-2024 vaccine dose during the study. Follow-up lasted 24 weeks and included symptom surveys and self-administered COVID-19 antigen testing, both occurring weekly. The primary aim was to compare VE (defined as prevention of symptomatic SARS-CoV-2 infection) between study-vaccinated participants and the control group. The secondary aim was to determine the relative VE of the Pfizer–BioNTech mRNA and Novavax 2023-2024 COVID-19 vaccines. Secondary objectives included assessing how the number of previous COVID-19 vaccinations impacted VE of the 2023-2024 COVID-19 vaccines; identifying predictors and associated factors for asymptomatic versus symptomatic infection and/or prolonged or severe illness; examining factors associated with post–COVID-19 conditions; and evaluating participants’ knowledge, attitudes, and practices related to COVID-19 ... |
