• Description:
  Introduction:
  
  The Announcement Approach using presumptive announcements increases human papillomavirus (HPV) vaccine uptake. This study seeks to understand the impact of the final Announcement Approach steps, easing parents’ vaccine concerns and then encouraging them to get HPV vaccine for their children, on parents’ HPV vaccine hesitancy and confidence in the vaccine’s benefits.
  
  Methods:
  
  In 2017–2018, investigators recruited an online national sample of 1,196 U.S. parents of children aged 9–17 years who had not yet completed the HPV vaccine series. Following the steps of the Announcement Approach, participants viewed brief videos of a pediatrician announcing the child was due for HPV vaccine (shown to all parents). In the 2 × 2 experiment, parents saw: (1) a video of the pediatrician attempting to ease a concern the parent had raised earlier in the survey (Ease video), (2) a video of the pediatrician encouraging the parent to get their child vaccinated (Encourage video), (3) both videos, or (4) neither video. Data analysis was conducted in spring 2020.
  
  Results:
  
  Seeing the Ease video message led to lower HPV vaccine hesitancy compared with not seeing it (mean=2.71, SD=1.29 vs mean=2.97, SD=1.33; p<0.001). The beneficial impact of easing concerns on lower vaccine hesitancy was explained by higher confidence (p<0.05). By contrast, the Encourage video had no impact on HPV vaccine hesitancy or confidence.
  
  Conclusion:
  
  Addressing parents’ concerns can decrease HPV vaccine hesitancy and increase confidence. Based on these findings, the Announcement Approach retained its emphasis on announcing children are due for vaccination and easing parent concerns.
