Abstract
The human papillomavirus (HPV) is a major public health concern affecting both females and males. HPV is associated with cervical, anal, head and neck cancers. About 99% of all cervical cancers are related to HPV. HPV vaccines, Gardasil, Cervarix, and Gardasil 9 are used in the primary prevention of HPV related cancers. Gardasil and Gardasil 9 are available for use in both females and males ages 9 to 26, while Cervarix is available for females ages 9 to 25. Gardasil 9 was approved by the FDA for prevention against additional HPV types. Despite the availability of this preventative measure against cervical cancer, the rate of HPV vaccination in the United States remains lower than that of other industrialized nations. The purpose of this study is to elucidate mechanisms to help increase the HPV vaccination rate by using education as a tool; by simplifying the president report so that lay person can understand the information presented in the report. Through the quantitative examination of the data from the states with the lowest and highest vaccination rates, using SPSS statistical analysis; we analyzed several factors involved with the low uptake of the vaccines. The results collected show that socioeconomic status, misconceptions about HPV, and misconceptions about the safety of the vaccines were identified as possible obstacles to the effective uptake of HPV vaccinations. The proposals made by the President's Cancer Panel to accelerate the uptake of vaccines include, increasing coverage of the vaccines through government-sponsored programs, and the Affordable Care Act; increasing accessibility to vaccines through pharmacies, schools, and clinics; and disseminating more information on HPV to healthcare providers, parents, caregivers, and patients. Allowing greater accessibility to the vaccines for all populations regardless of income, education, and eliminating misconceptions of the vaccines would play a significant role in eliminating cancer.Entities:

Figure 1Percentage of 13 to 17 Year-Old Girls Completing HPV Vaccines Series, and Cervical Cancer Incidence Rates by State, and HPV Vaccine Completion Percentage Map. HPV vaccine completion percentages are displayed in numerical value to their corresponding states. The colors represent the cervical cancer incidence rate bracket each state falls in. States with less than or equal to 30 percent vaccine completion rates are highlighted in red.
Percentages of 13 to 17 Year-Old Girls Completing HPV Vaccine Series. The Center for Disease Control (CDC) estimates that efforts to increase the current HPV vaccination rates to around 80% would prevent an additional 53,000 future cervical cancer cases among 12-year-old girls or younger. Table 3, also indicate that any number under 30% is considered low uptake.

HPV vaccines currently administered against cervical cancer causing HPV types. Gardasil, Cevarix and recently FDA approved vaccine Gardasil 9 could prevent the majority of cervical cancers if used optimally [6].
