Randomized Controlled TrialThe effect of screening for vaccine hesitancy on the subsequent development of hesitancy: a randomized controlled trial, Houston, TX.
Vaccine hesitancy remains a global health threat. Addressing parental vaccine hesitancy is essential to maintaining high vaccine coverage levels and preventing disease outbreaks; however, it is unknown if administering a vaccine hesitancy screening tool negatively impacts parental vaccine beliefs. We conducted a stratified randomized controlled trial in pediatric primary care practices. ⋯ The proportion of hesitant parents at 6 months did not differ between PACV and placebo groups (6.6% vs. 6.1%; p = .78) and the odds of hesitancy among PACV group participants was not higher than those in the placebo group (OR = 1.10; 95% CI: 0.63-1.93; p = .743). Race was the only characteristic significantly associated with vaccine hesitancy at 6-month follow up (p = .003). Overall, administration of the PACV did not trigger vaccine hesitancy in this study population.
