- Parental HPV vaccination intent remains low, and may be the largest barrier to initiation.
Why this matters
- Strong provider recommendations are needed to drive HPV vaccine initiation.
- Pair recommendations with follow-up counseling, reminder/recall strategies.
- 76,971 teenagers (parental intent analysis), 28,101 (reasons analysis).
- From 2010 to 2015, percentage of unvaccinated, undervaccinated teenagers declined (91.7% to 66.9%, 99.6% to 72.7%, among females, males, respectively).
- Parental intent to vaccinate unvaccinated males did not change significantly, while significant declines were seen in ‘not likely at all to vaccinate’ females (41.5% to 31.2% [difference, 10.3%; P<.001 significant increase in likely to vaccinate difference>
- Most prevalent reason for vaccine hesitancy: vaccine was unnecessary.
- Percentage of parents of females citing reason increased 25.8% to 32.7% (P=.02).
- Parents of males were significantly likelier to cite lack of provider recommendations for hesitancy over time (P<.001 style="list-style-type:circle;">
- Percentage reporting safety concerns/side effects as main reason increased from 7.3% to 14.8% (difference, 7.5%; 95% CI, 4.5%-10.5%).
