This study aims to assess patient-reported experiences following trivalent recombinant influenza vaccine (RIV3) vaccination using the Vaccinees' Perception of Injection (VAPI) questionnaire, identify factors related to vaccine choice and future vaccination intentions in each case, and assess the cross-validity of VAPI, by establishing magnitude of correlations to EuroQol 5 Dimensions, 5 Levels (EQ-5D-5L) domains. Participants will need approximately 30 minutes to complete the self-administered online survey. Individuals will be recruited via a U.S. retail chain partner that offers the RIV3 vaccine as part of their routine influenza vaccination program
