Study Summary

This study is a small-scale randomized, placebo-controlled factorial trial of two interventions to increase Tetanus, diphtheria and acellular pertussis (Tdap) immunization rates among infant caregivers. Specifically, the trial will compare a full cost vs. $5 Tdap voucher with or without an educational video.

Primary Outcome

The primary outcome of interest is the difference in vaccination rates between those who received the vouchers vs. those who did not and between those who received the educational video vs. those who did not. We are also interested in measuring whether the educational video acts as an effect modifier in the association between receipt of the voucher and vaccination rates.
