Potential health impact and cost-effectiveness of bivalent human papillomavirus (HPV) vaccination in Afghanistan

IntroductionHuman papillomavirus (HPV) vaccination has not been introduced in many countries in South-Central Asia, including Afghanistan, despite the sub-region having the highest incidence rate of cervical cancer in Asia. This study estimates the potential health impact and cost-effectiveness of HPV vaccination in Afghanistan to inform national decision-making.MethodAn Excel-based static cohort model was used to estimate the lifetime costs and health outcomes of vaccinating a single cohort of 9-year-old girls in the year 2018 with the bivalent HPV vaccine, compared to no vaccination. We also explored a scenario with a catch-up campaign for girls aged 10–14 years. Input parameters were based on local sources, published literature, or assumptions when no data was available. The primary outcome measure was the discounted cost per disability-adjusted life-year (DALY) averted, evaluated from both government and societal perspectives.ResultsVaccinating a single cohort of 9-year-old girls against HPV in Afghanistan could avert 1718 cervical cancer cases, 125 hospitalizations, and 1612 deaths over the lifetime of the cohort. The incremental cost-effectiveness ratio was US$426 per DALY averted from the government perspective and US$400 per DALY averted from the societal perspective. The estimated annual cost of the HPV vaccination program (US$3,343,311) represents approximately 3.53% of the country′s total immunization budget for 2018 or 0.13% of total health expenditures.ConclusionIn Afghanistan, HPV vaccine introduction targeting a single cohort is potentially cost-effective (0.7 times the GDP per capita of $586) from both the government and societal perspective with additional health benefits generated by a catch-up campaign, depending on the government′s willingness to pay for the projected health outcomes.     

Singaporean men's knowledge of cervical cancer and human papillomavirus (HPV) and their attitudes towards HPV vaccination

Little is known of men's knowledge of cervical cancer and its links with human papillomavirus (HPV), or of their attitudes and beliefs about HPV vaccination. This is despite men's sexual behaviour contributing to HPV transmission and their potential role in deciding whether their children are vaccinated against HPV. To address this, a comprehensive survey was conducted in Singapore where plans are underway for an HPV vaccination program. A representative sample of 930 Singaporean men was found to have moderate knowledge of cervical cancer but poor knowledge and awareness of HPV. Although these men showed strong support for HPV vaccination, overall findings highlight the importance of including men in education campaigns that aim to decrease the incidence of cervical and other HPV-related cancers and to increase the uptake of HPV vaccination.     

Knowledge,attitudes, and practices among Saudi women regarding cervical cancer,human papillomavirus (HPV) and corresponding vaccine

AimTo our knowledge there are no studies exploring Saudi women’s understanding of the importance of the human papillomavirus (HPV) vaccine. In the present study, we examined the awareness of HPV and women’s attitudes toward the HPV vaccine.MethodNine focus groups were formed in Riyadh City, Saudi Arabia, including 77 women between the ages of 18 and 45 years old. Face-to-face interviews were conducted in 58 female healthcare providers to examine women’s awareness of cervical cancer, HPV, barriers, acceptance, beliefs, and attitudes towards the HPV vaccine.ResultsFocus group discussions revealed a lack of knowledge and awareness of cervical cancer, HPV, and the HPV vaccine. Cultural concerns regarding screening and vaccinating for a conventionally known sexually transmitted infection were an emerging theme in addition to not perceiving cervical cancer screening as necessary because women with no signs and symptoms considered themselves not at risk for developing cervical cancer. Approximately 30% of healthcare providers other than physicians were unaware of prevention methods, and 63.3% did not practice any screening methods for cervical cancer and attributed the lack of screening to “no specific reasons at all”.ConclusionBecause of the unfavorable knowledge and attitude of HPV infection and the associated vaccine from the women in the present study, emphasis should be directed to educate and promote awareness of women to the risk factors of cervical cancer and to the need for screening programs and the administration of the vaccine.     

Knowledge differences between male and female university students about human papillomavirus (HPV) and cervical cancer: Implications for health strategies and vaccination

Knowledge about HPV and cervical cancer (CC) depends on several factors such as gender and education, which brings implications for health strategies and vaccination. A survey was conducted in Portugal with a representative sample of 1706 university students. Only 55.4% (n = 945) had already heard of HPV, although 88.3% (n = 834) from that know that is a risk factor for CC. 89% students (n = 841) wants to be vaccinated against it, but only 13.8% stated as main reason to be vaccinated “prevention of the disease”. Mean scores of knowledge were calculated. Statistical differences were found, regarding “CC knowledge”, in gender (p < 0.001) and between health sciences schools and non-health sciences schools (p < 0.001). Differences regarding the study area in “knowledge and beliefs of HPV” (p < 0.001) and in “relation between HPV and CC” (p < 0.001) were found. Therefore, these differences may help to develop effective strategies that lead to decline CC incidence and mortality.     

Human papillomavirus (HPV) vaccine uptake and completion at an urban hospital

Background

Despite the benefit of the human papillomavirus (HPV) vaccine in preventing cervical cancer, fewer than half of eligible young women in the United States have initiated the three-vaccine series. Among those who initiate HPV vaccination, large proportions do not complete the three-dose regimen.

Purpose

To evaluate racial and health insurance-related disparities in HPV vaccination.

Methods

We analyzed outpatient claims data for 8069 patients, ages 9-26 years, who had gynecologic visits at the University of Maryland Medical Center outpatient clinic from August 2006 to January 2010.

Results

Thirty-five percent of our sample initiated the vaccine series, including 91% of those ages 9-13. Only 11% of the sample and 33% of the 9-13 age group completed the 3 dose series. A higher proportion of blacks than whites (38% vs. 32%; p < 0.01) initiated, and 11% and 12%, respectively, of each race completed. Lower age was strongly correlated with uptake. After adjustment for insurance, blacks were less than half as likely as whites to complete the series in all age groups, and had 0.35 the odds (95% CI 0.26-0.46) of adherence. The uninsured had much lower race-adjusted odds than insured groups for initiation, but had similar adherence rates. Publicly insured individuals were more likely than the privately insured to complete all 3 doses.

Conclusions

Of the population of gynecologic service seekers seen at our university-based outpatient practice clinics, a significant minority initiate but do not complete the HPV vaccine series. More blacks than whites initiate the series, but similar proportions of the two races complete. Lack of insurance appears to be a major barrier to initiation, despite free vaccination programs.     

Human papillomavirus (HPV) vaccination in the transition between adolescence and adulthood

PurposeYoung adulthood is characterized by changes in health care decision-making, insurance coverage, and sexual risk. Although the human papillomavirus (HPV) vaccine is now approved for adults up to age 45, and catch-up vaccination is currently recommended up through age 26, vaccination rates remain low in young adults. This study explored perspectives on HPV vaccination among young adults receiving care at the student health center of a large public university.MethodsWe conducted semi-structured interviews (n = 27) and four focus groups with female and male undergraduate and graduate students (n = 18) and semi-structured interviews with health care providers (n = 6). Interviews and focus groups explored perceived risk of HPV infection, benefits of the HPV vaccine, and motivations for and barriers to HPV vaccination.ResultsMany young adults cited their parents’ views and recommendations from medical providers as influential on their decision-making process. Students perceived that cervical cancer prevention was a main benefit of the HPV vaccine and sexual activity was a risk factor for HPV infection. Students often lacked knowledge about the vaccine’s benefits for males and expressed some concerns about the safety and side effects of a vaccine perceived as new. Logistical barriers to vaccination included uncertainty over vaccination status and insurance coverage for the vaccine, and concerns about balancing the vaccine schedule with school obligations. Providers’ vaccine recommendations were impacted by health system factors, including clinical infrastructure, processes for recommending and documenting vaccination, and office visit priorities. Suggested vaccination promotion strategies included improving the timing and messaging of outreach efforts on campus and bolstering clinical infrastructure.ConclusionsAlthough college may be an opportune time to reach young adults for HPV vaccination, obstacles including navigating parental influence and independent decision-making, lack of awareness of vaccination status, and numerous logistical and system-level barriers may impede vaccination during this time.     

Knowledge and attitude of students studying at health department towards HPV and HPV vaccination

The human papillomavirus (HPV) is the most common diagnosed sexually transmitted infection in the world. The most frequent disease linked to HPV is cervical cancer as well as other cancers including those of the vulva, vagina, penis, anus, and oropharynx.Our research sought to evaluate the knowledge and attitudes concerning human papillomaviruses and their vaccine among students enrolled in Alt?nba? University's faculties of health sciences.MethodA cross-sectional study was carried out using a survey containing 41 questions about demographic variables, knowledge, and attitudes toward HPV and HPV vaccines. The questions were distributed to students via Google form using social media applications such as WhatsApp.ResultsThe study involved 144 students, 71.5 % of whom were female. 37.5 % of the participants learned about HPV from social media. Knowledge of HPV is present in 82 % of females and 25 % of males. Most of the questions had more accurate replies from female than from male students p < 0.05. As a result, 88 %, 46 % of female respondents and 27 %, 14 % of male respondents, respectively, correctly answered the questions about who should receive HPV vaccinations p < 0.001 and how many doses are necessary.ConclusionParticipants' awareness of HPV, HPV vaccination, and cervical cancer was rather high when compared to other research. However, there are knowledge gaps that need to be corrected and provided through educational programs.     

Knowledge and attitudes about human papillomavirus (HPV) and HPV vaccines among women living in metropolitan and rural regions of China

Infection with the human papillomavirus (HPV) is one of the most common sexually transmitted infections and causes virtually all cervical cancer globally. The recent development of two safe and clinically effective vaccines against HPV is a promising step towards lowering cervical cancer rates in the future. What Chinese women think about HPV and the vaccines remains unknown. We undertook a population-based survey, which was embedded in a cervical cancer screening project and was designed to assess women's knowledge about HPV and their acceptability to the vaccines. We found that only 15.0% of women in our study reported to have ever heard of HPV, and this knowledge differs by rural (9.3%) and metropolitan areas (21.6%) and also by education. Most (84.6%) participants were willing to be vaccinated if HPV vaccine became available to them. The present study documents ways in which women learn about HPV and indicates the potential barriers and success of introducing HPV vaccine to China.     

Knowledge of human papillomavirus (HPV) and HPV vaccination: An international comparison

Since vaccination against human papillomavirus (HPV) became available, awareness of HPV has dramatically increased. Implementation of a vaccine program varies internationally yet no studies have explored the influence this has on the public's knowledge of HPV. The present study aimed to explore differences in awareness of HPV and HPV knowledge across three countries: The US, UK and Australia.     

Community-based household assessment of human papillomavirus (HPV) vaccination coverage and acceptability – HPV vaccine demonstration program,Cambodia – 2017

Background

In 2017, the Cambodia Ministry of Health introduced human papillomavirus (HPV) vaccine through primarily school-based vaccination targeting 9-year-old girls. Vaccination with a two-dose series of HPV vaccine took place in six districts in two provinces as a demonstration program, to better understand HPV vaccine delivery in Cambodia.

Human papillomavirus vaccination coverage in Luxembourg – Implications of lowering and restricting target age groups

BackgroundIn Luxembourg, a national Human Papillomavirus (HPV) vaccination programme was introduced in 2008, targeting 12–17 year old girls offering a choice of bivalent or quadrivalent vaccine free of charge. In 2015, the programme was changed offering the bivalent vaccine only to 11–13 year old girls. The aim of this study was to evaluate the HPV vaccination coverage, to assess the impact of age target changes and compare vaccination coverage to other European countries.MethodsAnonymous HPV vaccination records consisting of individual vaccine doses obtained free of charge in pharmacies between 2008 and 2016 were extracted from the Luxembourgish Social Security database. Additional aggregate tables by nationality and municipality were analysed.ResultsOf the target cohort of 39,610 girls born between 1991 and 2003 residing in Luxembourg, 24,550 (62.0%) subjects obtained at least one dose, 22,082 (55.7%) obtained at least two doses, and 17,197 (43.4%) obtained three doses of HPV vaccine. The mean age at first dose was 13.7 years during 2008–14 and 12.7 years in 2016 after the age target change. Coverage varied significantly by nationality (p < 0.0001): Portuguese (80%), former Yugoslavs (74%), Luxembourgish (54%), Belgian (52%), German (47%), French (39%) and other nationalities (51%). Coverage varied also by geographical region, with lower rates (<50%) noted in some Northern and Central areas of Luxembourg (range: 38% to 78%).ConclusionOverall HPV vaccination coverage in Luxembourg is moderate and varied by nationality and region. The policy changes in 2015 did not have a substantial impact except lowering age at initiating vaccination. Options to improve coverage deserve further investigation.     

Decline in prevalence of human papillomavirus infection following vaccination among Australian Indigenous women,a population at higher risk of cervical cancer: The VIP-I study

BackgroundCervical cancer occurrence and mortality are strongly correlated with socioeconomic disadvantage, largely due to unequal access to screening and treatment. Universal human papillomavirus (HPV) vaccination provides the opportunity to greatly reduce this global health disparity. Australian Indigenous women have substantially higher rates of cervical cancer than non-Indigenous women, primarily due to under-screening. We investigated HPV infection rates in Indigenous women 7 years after implementation of the national HPV vaccination program.MethodsWe used a repeat cross-sectional design, with the baseline being provided by an HPV prevalence survey among Indigenous women attending clinics for cervical cytology screening, prior to the start of the vaccination program in 2007. We returned to clinics in four locations during 2014–15, and invited women aged 18–26 years attending for screening to provide a cervical specimen for HPV testing, as well as to complete a short questionnaire and consent to allow access of their records in the National HPV Vaccination Program Register. We used well-established laboratory methods to test specimens for specific HPV genotypes.ResultsA total of 142 women were recruited at participating sites and compared to 155 who had been recruited at the same locations in the 2007 pre-vaccine survey. The two groups were identical in regard to age, with the more recent group having a higher proportion of hormonal contraception users, and a lower proportion of smokers. The proportion found to have any HPV type fell from 58 to 36% with the decline being entirely due to reductions in vaccine types, which fell by 94% from 24 to 1.4%.ConclusionAustralia’s national HPV vaccination program appears to be successfully protecting a very high proportion of Indigenous women against vaccine targeted HPV types, who have in the past been at elevated risk of cervical cancer.     

A qualitative study investigating knowledge and attitudes regarding human papillomavirus (HPV) and the HPV vaccine among parents of immunosuppressed children

Barriers influencing the willingness of parents to vaccinate immunocompetent children include a lack of knowledge about human papillomavirus (HPV) and low perception of risk regarding their child's acquisition of HPV infection. However, it cannot be assumed that the facilitators and barriers of HPV vaccination are the same for parents/guardians of children who are immunocompromised, or who have chronic medical conditions. This study aimed to document the knowledge and attitudes of parents/guardians of immunosuppressed children and adolescents towards HPV infection and the vaccine.     

Planning for human papillomavirus (HPV) vaccination in sub-Saharan Africa: A modeling-based approach

Background

Human papillomavirus (HPV) vaccines have the potential to reduce cervical cancer incidence and mortality, particularly in the parts of the developing world that bear the greatest burden of disease. This research sought to predict the impact and cost-effectiveness of an HPV vaccination program in an example low-resource country with a high burden of cervical cancer: Mali, West Africa.

Methods

Novel compartmental mathematical models projected the impact of adolescent HPV vaccination in urban and rural areas of Mali. The models accounted for two high-risk vaccine-types: HPV 16 and 18. We then attached comprehensive real cost and cost-effectiveness estimates.

Results

Our models predict that HPV vaccination in Mali will reduce cervical cancer burden by a factor roughly equal to vaccine coverage. A point vaccination program was simulated in a cohort of 333,146 urban and 588,982 rural Malian women, age 10–14. Vaccination of 50% of girls reduced the peak prevalence of HPV 16/18 to 5.0% in the urban setting and 9.6% in the rural setting, down from 11.7% and 22.0%, respectively, with no vaccination. The 50% vaccination scenario averted 1145 cervical cancer deaths in the urban group and 2742 in the rural group. The cost per discounted life-year saved in this scenario was 1030 US dollars (urban) and 725 dollars (rural). The cost per life-year saved was higher at 90% coverage, but was still in the range of a “cost-effective” public health intervention.

Conclusions

This research yielded the most comprehensive real cost estimates of HPV vaccination yet published for sub-Saharan Africa. Our models indicate that HPV vaccination in Mali will be cost-effective when introduced. To maximize the benefit using limited resources, vaccination programs may begin with a target coverage of about 50%. We anticipate that costs of reaching late adopters after the First Vaccinated Wave of vaccination will be higher, but worthwhile.     

A single dose of quadrivalent human papillomavirus (HPV) vaccine is immunogenic and reduces HPV detection rates in young women in Mongolia,six years after vaccination

BackgroundEmerging observational evidence suggests a single-dose of human papillomavirus (HPV) vaccine may be protective against vaccine-targeted HPV infection and associated cervical dysplasia. We aimed to demonstrate whether a single dose of quadrivalent HPV (4vHPV) vaccine was immunogenic and reduced HPV detection rates in young women in Mongolia. We also assessed knowledge and attitudes regarding HPV and the HPV vaccine.MethodsA retrospective paired cohort study was undertaken to evaluate the effect of a single dose of 4vHPV, given at age 11–17 years in 2012, on HPV detection rates, when compared with unvaccinated women. Real time PCR was performed on self-administered vaginal swabs for HPV detection. An immunological analysis detecting neutralising antibodies (NAb) to high-risk HPV (HRHPV) genotypes 16 and 18 was performed on sera from a subset of 58 participants. Questionnaires evaluated knowledge, attitudes and self-swab acceptability.FindingsA total of 475 women (mean age 20.4 years ± 1.6) were recruited; 118 vaccinated and 357 unvaccinated women. The prevalence of vaccine-targeted HRHPV16 and 18 was reduced by 92% (95%CI 44–99%) in the vaccinated (1·1%) compared with the unvaccinated (15.4%) group. The percentage of non-vaccine HPV genotypes was similar between vaccinated (26.5%) and unvaccinated (26.7%) groups. Approximately 90% and 58% of vaccinated women remained seropositive after six years for HRHPV16 and 18, respectively, with neutralising antibody levels 5- and 2-fold higher than unvaccinated women (p < 0.001).InterpretationOne dose of 4vHPV vaccine reduces vaccine-targeted HPV genotypes, six years following vaccination, with high levels of HR genotype seropositivity among young Mongolian women.     

Parental acceptance of human papillomavirus (HPV) vaccination in Indonesia: a cross-sectional study

Background

Cervical cancer ranks the second most frequent cancer in Indonesian women. In Indonesia, human papillomavirus (HPV) vaccine acceptance has not been studied before.

Objective

To determine parental HPV vaccine acceptance in Indonesia, and factors that influence their decision. Factors include sociodemographic factors, knowledge of HPV, HPV vaccination and cervical cancer, health beliefs about cervical cancer, and attitudes towards vaccination in general.

Methods

746 parents, with at least 1 daughter aged 0-14, were interviewed using questionnaires based on published and adjusted interviews. Interviews were done in sub district public health centers, general governmental hospitals, and via house-visits, in 5 Indonesian provinces.

Results

Parental HPV vaccine acceptance was 96.1%. Logistic regression revealed that age, beliefs regarding cervical cancer, and attitudes towards vaccination in general were significantly associated with HPV vaccine acceptance. Of the participants, 66.0%, 16.6%, and 15.8% had heard about cervical cancer, HPV, and HPV vaccination respectively. The mean total knowledge score was 1.91(Standard Deviation 2.31) on a 0-8 scale. Health beliefs about cervical cancer and attitudes towards vaccination in general were positive. Participants named the high cost of the vaccine, fear for side-effects, and chosen vaccination locations as possible barriers towards HPV vaccine implementation.

Discussion

Parental HPV vaccine acceptance is high, but knowledge about HPV and cervical cancer is low. During HPV vaccination programs, focus should not only be on providing information, but also on existing beliefs and attitudes towards cervical cancer and vaccination in general. If HPV vaccination programs were to be implemented in Indonesia, the indicated barriers should be taken into account.     

Human papillomavirus vaccination and Pap testing profile in Manitoba,Canada

Background

Females who receive the human papillomavirus (HPV) vaccine may believe they are protected from developing cervical cancer and no longer require screening. Concern has also been expressed that vaccinated females are those that would be screened regularly. This study assesses the Pap testing behavior of vaccinated and non-vaccinated females.

Methods

For this population-based retrospective cohort study, vaccination and screening registries were linked for 3540 vaccinated females aged 15 years and over and 9592 matched non-vaccinated females. Conditional logistic regression, the Kaplan–Meier method and Cox regression were used to examine the association between vaccination and Pap testing.

Results

Vaccinated females were more likely to have had a Pap test within the year prior to the index date than non-vaccinated females (15–19 years old: OR = 1.38, 95% CI 1.20–1.59; 20+ years old: OR = 2.34, 95% CI 1.98–2.76). In the three-year period after the index date, vaccinated females had a significantly higher cumulative probability of having a Pap test (83.3%) than non-vaccinated females (66.1%). Females who had a Pap test within three years prior to the index date were more likely to have a Pap test after the index date (vaccinated: HR = 5.03, 95% CI 4.65–5.45; non-vaccinated HR = 3.97, 95% CI 3.70–4.24). Being vaccinated had a significant effect on Pap testing (15–19 years old: HR = 1.54, 95% CI 1.39–1.69; 20+ years old: HR = 1.87, 95% CI 1.52–2.31). 80.1% of vaccinated females who had a Pap test prior to the index date also had one subsequent to it, compared to 70.1% for non-vaccinated females. 41.1% of females had not been vaccinated nor had a Pap test.

Conclusion

The majority of vaccinated females continue to participate in screening, and do so at a higher rate than non-vaccinated females. Renewed efforts need to be made to include the large proportion of non–vaccinated, non–screened females in vaccination and/or screening.     

Health beliefs of Taiwanese women seeking HPV vaccination

In Taiwan, human papillomavirus (HPV) vaccine is recommended for women aged 9–26 years. The purpose of this study was to examine health beliefs and reasons for HPV vaccination among young adult women (aged 18–26 years), and adult women (aged over 26 years). Women who initiated HPV vaccination were recruited from three hospitals in southern Taiwan. One hundred and eighty-nine subjects completed a questionnaire on health beliefs and reasons for HPV vaccinations. 38% (n = 72) of the women who initiated vaccination were over the age of 26. Health beliefs regarding HPV vaccination differ between young adult women and adult women. Recommendations from others (family, health care providers, etc.) are among the main reasons for young adult women to initiate HPV vaccination; while self-awareness of the risk for HPV infection and personal gynecologic diseases are main reasons for adult women to initiate HPV vaccination. Furthermore, women aged 18–26 are more likely than women aged over 26 to consider the cost and availability of vaccination. Media also plays an important role in a woman's decision to seek HPV vaccination.     

澳门妇女和医师对HPV疫苗的认知态度调查及其推广应用分析

目的了解澳门特别行政区女性和执业医师在人乳头瘤病毒(human papillomavirus,HPV)疫苗纳入免费防疫接种计划之前对其认知、接受度,及疫苗的使用情况,分析影响接种的主要因素,评估HPV疫苗在澳门发展情况,为宫颈癌预防工作提供适当的模式。方法 2008年8~12月采用问卷抽样调查方式对澳门特别行政区1 716名女性及108名执业医师进行问卷调查,利用SPSS 13.5软件进行统计分析。结果受调查妇女中,47.1%的女性曾听过HPV,76.7%的女性听过宫颈癌疫苗,认为HPV感染与宫颈癌有关联性的仅为35.4%。另外,38.4%的女性及其中43.4%的母亲愿意自己或女儿接种疫苗。据多因素logistic回归分析得出年龄、个人收入、职业、个人防护、担心患宫颈癌、担心疫苗来源、认为自己年龄太大或太小是影响接受疫苗的主要因素。澳门医师对HPV及HPV疫苗都有中高度认知。约60%受调查医师对HPV疫苗有信心,而评价疫苗的不足主要是价格太贵。结论澳门宣传有关HPV及HPV疫苗的知识是有效的,HPV疫苗在澳门使用人数逐渐增加。为增加澳门居民对疫苗的接受程度,达到预防宫颈癌的目的,政府仍需采用多种宣传方式加强宣传力度。     

Factors associated with human papillomavirus vaccination among young adult women in the United States

Background

Human papillomavirus (HPV) vaccination is recommended to protect against HPV-related diseases.

Objective

To estimate HPV vaccine coverage and assess factors associated with vaccine awareness, initiation and receipt of 3 doses among women age 18–30 years.

Methods

Data from the 2010 National Health Interview Survey were analyzed to assess associations of HPV vaccination among women age 18–26 (n = 1866) and 27–30 years (n = 1028) with previous HPV exposure, cervical cancer screening and selected demographic, health care and behavioral characteristics using bivariate analysis and multivariable logistic regression.

Results

Overall, 23.2% of women age 18–26 and 6.7% of women age 27–30 years reported receiving at least 1 dose of HPV vaccine. In multivariable analyses among women age 18–26 years, not being married, having a regular physician, seeing a physician or obstetrician/gynecologist in the past year, influenza vaccination in the past year, and receipt of other recommended vaccines were associated with HPV vaccination. One-third of unvaccinated women age 18–26 years (n = 490) were interested in receiving HPV vaccine. Among women who were not interested in receiving HPV vaccine (n = 920), the main reasons reported included: not needing the vaccine (41.3%); concerns about safety of the vaccine (12.5%); not knowing enough about the vaccine (11.9%); not being sexually active (8.2%); a doctor not recommending the vaccine (7.6%); and already having HPV (2.7%). Among women with health insurance, 10 or more physician contacts within the past year and no contraindications, 74.5% reported not receiving HPV vaccine.

Conclusions

HPV vaccination coverage among women age 18–26 years remains low. Opportunities to vaccinate are missed. Healthcare providers can play an important role in educating young women about HPV and encouraging vaccination. Successful public health and educational interventions will need to address physician attitudes and practice patterns and other factors that influence vaccination behaviors.
