The Efficacy of the 2023-2024 Updated COVID-19 Vaccines Against COVID-19 Infection

Summary

The purpose of this research study is to find out how well two different 2023-2024 updated COVID-19 vaccines protect people from COVID-19 (the disease caused by the SARS-CoV-2 virus), and to determine if getting a 2023-2024 updated vaccine provides better protection from COVID-19 than not getting a vaccine. If the participant chooses to get a 2023-2024 updated COVID-19 vaccine as part of this study, they will have a 50/50 chance of receiving either the Novavax or Pfizer mRNA vaccine. If the participant decides not to get a 2023-2024 updated COVID-19 vaccine, the participant can still participate in other study activities. STUDY ACTIVITIES: * An online enrollment survey * An in-person enrollment visit * Weekly online surveys for 20 weeks * Weekly COVID-19 tests for 20 weeks * Additional online surveys if you have COVID-19 symptoms or tested positive for COVID-19. * Additional COVID-19 tests if you have COVID-19 symptoms or tested positive. * Online survey questions in the middle and at the end of the study
