Many Americans fail to get life-saving vaccines each year, and the availability of a vaccine for COVID-19 makes challenge encouraging vaccination more urgent than ever. We present large field experiment ( N = 47,306) testing 19 nudges delivered patients via text message designed boost adoption influenza vaccine. Our findings suggest that messages sent prior primary care visit can rates by an average 5%. Overall, interventions performed better when they were 1) framed as reminders flu shots...
Alternative immunization schedules increase the time a child is unvaccinated and require greater resources from providers. Understanding what drives interest in alternative can potentially inform design of effective, targeted messages that help to reduce spent counseling decrease requests for schedules. This study used Theory Planned Behavior explore associations between sources vaccine information, parental concerns, peer norms behavior intentions follow an schedule. We performed logistic...

HIV testing coverage in sub-Saharan Africa is lower among men than women. We investigated the impact of a peer-delivered U = (undetectable equals untransmittable) message on men's uptake through cluster randomised trial with individual mobile clinic days as unit randomisation. On standard care (SOC) days, peer promoters informed about availability at clinic. intervention delivered messages. used logistic regression adjusting for location, clustering by study day, to determine percentage...
<h3>Importance</h3> Despite the availability of safe and effective vaccines, many people fail to get vaccinated. Messages using behavioral science principles may increase vaccination rates. <h3>Objective</h3> To determine effect on influenza rates a text message telling patients that an vaccine had been reserved for them. <h3>Design, Setting, Participants</h3> As part larger messaging megastudy, in this randomized clinical trial, 11 188 2 large health systems were assigned receive stated "a...
