 The study found that physician recommendation was the most important factor associated with reported child HPV vaccination status with mothers who received the provider recommendation being 32 times more likely to have a vaccinated child. Knowing someone who had received the vaccine and prior HPV diagnosis or knowing someone with cervical cancer were also strongly associated with vaccination uptake. Mothers perceived moderate to high risk for their child contracting HPV or developing genital warts or cervical cancer were more likely to report that their daughters, but not their sons, had been vaccinated.
