In a safety net population HPV4 vaccine adherence worsens as BMI increases.

Objectives: Obesity adversely inhibits antibody response to vaccination. Three doses of HPV4 may or may not provide adequate long term protection against HPV 16/18 in obese females. The aim of this study was to determine whether adherence to HPV4 vaccination in a safety net population was reduced with increasing body mass index (BMI).

Urban and rural safety net health care system clinics: no disparity in HPV4 vaccine completion rates.

Objective: Safety net health care centers in the US serve vulnerable and underinsured females. The primary aim of this work was to determine if HPV4 dosing compliance differs between females who receive doses at rural vs. urban core safety net health care locations.

The influence of free quadrivalent human papillomavirus vaccine (HPV4) on the timely completion of the three dose series.

Objective: Economic incentives can positively influence social determinants to improve the health care of the uninsured and underserved populations. The aim of this study was to determine if free HPV4 vaccine would lead to on-time series completion in our safety net health care system in the US Midwest.

Methods: A nested retrospective cohort study of females receiving HPV4 vaccine between 2006 and 2009 was conducted.
