Official title

Financial Incentives for Influenza Vaccination

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

In this work, we are assessing the impact of messaging with or without a $50 financial incentive on influenza vaccination rates in a county health system. Our main hypothesis is that a message with a $50 financial incentive will increase vaccination rates relative to a control/"treatment as usual" group. We further hypothesize that the financial incentive will increase vaccination rates relative to the message only arm.
