- Type
- PRIMARY
- Title
Part B: Number of Participants With a First Occurrence of CDC-based COVID-19 Starting 14 Days After Month 6 Dose Until End of Follow up in RM6 Cohort Between Month 6 Monovalent and Bivalent Boost Groups
- Description
The CDC-based COVID-19 endpoint is defined as the first occurrence of symptomatic NAAT-confirmed COVID-19 based on the following criteria: 1. At least ONE of the following systemic or respiratory symptoms: Fever (≥ 38C), chills, cough, shortness of breath and/or difficulty breathing, fatigue, muscle and/or body aches \[not related to exercise\], headache, new loss of taste/smell, sore throat, congestion, runny nose, nausea, vomiting, or diarrhea, AND 2. At least ONE (post-baseline) nasal swab (or respiratory sample, if hospitalized) positive for SARS-CoV-2 by NAAT. 3. The symptom date and NAAT positive date must be within 14 days of each other. The date of a COVID-19 endpoint according to the CDC-based definition is the earlier date of a symptom and the date of positive NAAT that satisfy the criteria stated above. The CDC criteria do not require adjudication.
- Time frame
- 14 days after Month 6 dose until end of follow up (up to 18 months)
- Population
- Participants in FAS who received a Month 6 vaccination under the randomization scheme (RM6 cohort).
