A Study to Evaluate the Safety and Immunogenicity of COVID-19 Vaccine and Influenza Combination Vaccine

Phase 3
Active, not recruiting
Conditions
COVID-19
Interventions
Biological: CIC Vaccine Co-formulated tNIV2 , SARSCoV-2 rS and Matrix-M Adjuvant
Biological: tNIV Vaccine
Biological: Fluzone High Dose
Registration Number
NCT06291857
Lead Sponsor
Novavax
Brief Summary

This is a medical study where participants will be randomly assigned to receive either a new combination vaccine that protects against both COVID-19 and the flu, or a standard flu vaccine. The researchers conducting the study won't know which vaccine each participant receives, ensuring their observations are unbiased. This study compares the new combination vaccine to an already available flu vaccine to see how well it works. It's a large-scale, final-stage study designed to thoroughly check how well the vaccines trigger an immune response (immunogenicity) and how safe they are.

Detailed Description

The study will enroll up to approximately 7,022,000 medically stable (based on history and physical examination) adult male and female participants ≥ 65 65 years of age in Part 1 and up to approximately 2,300 medically stable (based on history and physical examination) adult male and female participants ≥ 65 years of age in Part 2. In Part 1, pParticipants will be randomly assigned to receive either CIC, Novavax COVID-19 Vaccine, tNIV, or Fluzone High-Dose in a 3:2:1:3 ratio, respectively. All participants will receive a single intramuscular (IM) injection on Day 0, will remain on study for immunogenicity data collection through Day 182 and safety data collection through Day 364 (End of Study \[EoS\]).
