This study will investigate antibody levels with respect to time since receiving a COVID-19 booster shot. The study will be decentralized, where participants can complete all study tasks at home. Self-reported participant information will be collected via surveys conducted at intake and monthly throughout the study. Participants will also perform monthly at-home capillary blood draws via YourBio devices that will be mailed to the designated laboratory for sample processing and antibody testing.
