Takeaway

  • English and Welsh parent awareness of HPV vaccine, inclusion of/intent to vaccinate adolescent boys remains low.

Why this matters

  • Provide information about HPV cancer risks, vaccine safety/effectiveness to parents/decision-makers to address information lapses, hesitancy.

Key results

  • 1049 participants; mean age, 40.5 years; 61% mothers.
  • 55% had heard of HPV; 55% vs 23% aware of HPV vaccination for girls, boys, respectively.
  • Significant differences noted in Precaution Adoption Process Model (PAPM) stage by sex; 68.6% vs 55.9% parents of girls, boys, respectively, would vaccinate (P<.0001>
  • Parents of boys likelier to be undecided (32.9% vs 27.9%, respectively).
  • Major reasons for indecision: need more information (54%), side effects (33%).
  • Multivariate, model 3: mothers likelier than fathers to vaccinate: OR, 1.62 (95% CI, 1.10-2.39).
  • Past vaccine refusal equal across models 1, 2, 3 (OR, 4.96 [95% CI, 2.41-10.21]; 4.70 [2.31-9.57]; 4.77 [2.26-10.05], respectively).
  • HPV vaccine attitudes strongest predictors of vaccination intent (OR, 60.96; 95% CI, 24.49-151.76).

Study design

  • Cross-sectional, population-based survey evaluating English/Welsh parents’ HPV awareness, vaccination inclusion of boys.
  • Multivariate analyses, 3 models, 1: pseudo R2=12% (parent/child sex, past refusal); 2: R2=21% (HPV/vaccine awareness); 3: R2=47% (vaccine attitudes).
  • Funding: Cancer Research UK.

Limitations

  • Sample bias.
  • Inability to assess response rate.
