Could Poor Parental Recall of HPV Vaccination Contribute to Low Vaccination Rates?

Introduction: Rates of initiation and completion of the human papillomavirus (HPV) vaccine series remain below national goals. Because parents are responsible for ensuring vaccination of their children, we examined the accuracy of parental recall of the number of shots their daughters received.

Methods: Parents/guardians of girls aged 11 to 17 years were asked to recall the number of HPV doses received by their daughters. Dose number was confirmed using provider-verified medical records. Logistic regression assessed variables associated with correct recall.

Results: A total of 79 (63%) parents/guardians correctly identified the number of shots their daughters received. Ninety-one (73%) were aware of whether their daughter started the series at all. The only factor significantly associated with accurate recall in logistic regression models was female gender of parent/guardian.

Conclusion: Nearly 40% of parents/guardians inaccurately recalled the number of HPV shots their children received, which may contribute to low rates of vaccine initiation and completion.
