So why is coverage lower than it is for other recommended vaccines?
In the National Immunization Survey, we ask parents of unvaccinated adolescents, who indicated that they do not intend to have their child vaccinated in the next 12 months, why their child is not vaccinated.
In the 2017 survey, the most common reason reported by parents of both boys and girls was concern about safety or side effects. The other reasons – that HPV vaccine was not needed or necessary, that it was not recommended, that they don’t really know about it, or that their child is not sexually active – could all at least potentially be addressed by a strong provider recommendation. In surveys of pediatricians and family physicians, immunization providers acknowledge that they do not consistently give a strong recommendation for HPV vaccine at the recommended age of 11 to 12 years.
