Mothers' preferences and willingness-to-pay for human papillomavirus vaccines in Iran: A discrete choice experiment study. Prev Med Rep 2021; 23:101438. [PMID: 34189022 PMCID: PMC8220373 DOI: 10.1016/j.pmedr.2021.101438] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2021] [Revised: 05/22/2021] [Accepted: 05/31/2021] [Indexed: 11/05/2022] Open
Abstract
The relative importance for serious side effects was the highest among all attributes. Mothers express more WTP for the quadrivalent vaccine compared to bivalent due to its protection against genital warts. Quadrivalent vaccination could be the most suitable candidate for implementation in the national immunization schedule.
This study aimed to identify mothers’ preferences and willingness-to-pay (WTP) for human papillomavirus (HPV) vaccines (in this case, bivalent and quadrivalent) in Iran. We used a discrete choice experiment (DCE) method to present mothers with choices between two hypothetical profiles of vaccines, described by combinations of five attributes, each with two or three levels. We analyzed the DCE results using conditional logistic regression and measured WTP estimates for each attribute. Our response rate was 53.96%, while the completion rate for questioner was 93.57%. We identified protection against cervical cancer, protection against genital warts, protection duration, serious side effects, and cost to influence mothers’ preferences for HPV vaccination. The relative importance for serious side effects was the highest among all attributes. Mothers’ WTP for bivalent and quadrivalent HPV vaccines was in US $ −432 (US $1 = IRR 42,000) and US $ 380, respectively. Quadrivalent vaccination could be the most suitable candidate for implementing the national immunization schedule. The reason is that mothers express more WTP for the quadrivalent vaccine than bivalent due to its protection against genital warts.

Fokom Domgue J, Chido-Amajuoyi OG, Yu RK, Shete S. Beliefs About HPV Vaccine's Success at Cervical Cancer Prevention Among Adult US Women. JNCI Cancer Spectr 2019; 3:pkz064. [PMID: 32280919 PMCID: PMC6901081 DOI: 10.1093/jncics/pkz064] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2019] [Revised: 07/30/2019] [Accepted: 08/08/2019] [Indexed: 01/01/2023] Open
Abstract
Background Beliefs are known to be a key determinant in vaccines’ uptake. However, little is known about beliefs surrounding the success of the human papillomavirus (HPV) vaccine in preventing cervical cancer in the United States. Methods Data from the Health Information National Trends Survey 5 Cycle 1 (2017) were analyzed for 1851 female respondents aged 18 years and older. Weighted multinomial logistic regression was employed to determine predictors of beliefs in the success of the HPV vaccine in preventing cervical cancer. Results Overall, 29.8% of women believed that HPV vaccine is successful in preventing cervical cancer, 6.6% believed it is not successful, and 63.6% did not know if the HPV vaccine is successful. Non-Hispanic blacks (adjusted odds ratio [aOR] = 1.80, 95% confidence interval [CI] = 1.16 to 2.79), women with no more than 12 years of education (aOR = 2.05, 95% CI = 1.17 to 3.60), those who did not know if they were advised by a health-care provider to get an HPV shot within the last 12 months (aOR = 4.19, 95% CI = 1.39 to 12.60), and those unaware of a family cancer history (aOR = 5.17, 95% CI = 1.48 to 18.21) were more likely to not know whether the HPV vaccine prevents cervical cancer. Women younger than 65 years were more likely than elderly to believe that the HPV vaccine is not successful at preventing cervical cancer. Conclusions A substantial proportion of US women are uninformed about the HPV vaccine. To accelerate progress in the HPV vaccine’s uptake, future interventions should incorporate educational programs, particularly targeting Non-Hispanic blacks, women with a lower level of education, and those younger than 65 years. Health-care providers’ participation in promotion of patient education about HPV vaccination should also be increased.

Abstract
AIM This study examined the determinants of attitudes and beliefs about human papillomavirus (HPV) infection, cervical cancer and HPV vaccine among parents of adolescent girls in Mysore, India. METHODS A random sample of 800 parents who had at least one adolescent-aged daughter attending school were recruited for a survey. RESULTS Most parents (n = 778; 97.3%) completed the survey. Compared to Hindus, Muslims were more likely to perceive that their daughters are susceptible to HPV infection (adjusted odds ratio [aOR]: 4.94; 95% confidence interval [CI]: 2.87, 8.49) or cervical cancer (aOR: 2.73; 95% CI: 1.55, 4.80). However, the likelihood of perceiving that daughters are susceptible to HPV infection (aOR: 0.94; 95% CI: 0.90, 0.98) or cervical cancer (aOR: 0.95; 95% CI: 0.92, 0.99) decreased with an increase in the age of the parents. Perceived severity of HPV infection (aOR: 0.36; 95% CI: 0.14, 0.97) and cervical cancer (aOR: 0.33; 95% CI: 0.15, 0.74) was lower among Muslims than Hindus. Muslims had lower odds of believing that HPV vaccine is safe (aOR: 0.47; 95% CI: 0.25, 0.89) or could protect against cervical cancer (aOR: 0.27; 95% CI: 0.16, 0.48), but were more likely to feel that HPV vaccination may cause girls to become more sexually active (aOR: 1.92; 95% CI: 1.09, 3.39). The odds of believing that HPV vaccine is effective increased with an increase in the age of the parents (aOR: 1.03; 95% CI: 1.003, 1.06). CONCLUSION Among Indian parents, age and religion of parents are associated with parental attitudes and beliefs about the threat of HPV and cervical cancer as well as the risks and benefits of HPV vaccine.

Abstract
A scoping review was performed to identify factors that may lead to human papillomavirus (HPV) vaccine hesitancy among women in low- and middle-income countries in South East Asian Region (SEAR) and Western Pacific Region (WPR). A systematic search of English and non-English articles using Pubmed, EMBASE, PsycINFO, Cochrane, MEDLINE, and CINAHL plus was conducted. Only 63 studies conducted in SEAR and WPR were included from inception until December 2016. Results of these studies have shown that poor awareness and knowledge of practices on cervical cancer prevention was evident in both SEAR and WPR. Concerns on safety and efficacy of the vaccine, and costs in getting vaccinated were significant barriers. Most women stated that they needed more information, and strongly welcomed a physician's recommendation in both geographical regions. Women also felt they have a low risk of acquiring HPV infection and cervical cancer. Most women in SEAR and WPR were unable to decide on whether to accept HPV vaccination.

Abstract
The Human Papillomavirus (HPV) vaccine has the great potential to prevent HPV-related infections for millions of women and men worldwide. However, the success of the vaccine is highly dependent on the vaccination rate. Factors influencing the attitudes of undergraduate students towards HPV vaccination should be studied. This is a cross-sectional survey that was conducted to estimate the HPV vaccination rate among undergraduate students in Hong Kong, and to identify the predictors of their attitude towards HPV vaccination. The results showed that the HPV vaccination rate was 13.3%. Factors related to knowledge of vaccination were the main predictors of the students’ attitude towards vaccination (there were seven predictors, with B = 1.36 to 2.30; p < 0.05), followed by gender (B = −1.40; p < 0.05), acceptable maximum price (B = 0.35; p < 0.05), and willingness to receive the HPV vaccine if it can protect against cervical/anal cancer and genital warts (B = −1.90; p < 0.001). The regression model that was developed based on the predictors had a moderate effect size (adj-R2 = 0.33). To conclude, the HPV vaccination rate among undergraduate students in Hong Kong was low. They should be provided with more active education and activities to promote HPV vaccination to improve their knowledge on the subject.

Choi HCW, Leung GM, Woo PPS, Jit M, Wu JT. Acceptability and uptake of female adolescent HPV vaccination in Hong Kong: a survey of mothers and adolescents. Vaccine 2013; 32:78-84. [PMID: 24188759 DOI: 10.1016/j.vaccine.2013.10.068] [Citation(s) in RCA: 43] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2013] [Revised: 10/14/2013] [Accepted: 10/22/2013] [Indexed: 11/17/2022]
Abstract
BACKGROUND Organized population-based HPV vaccination programs can be effective in reducing the burden of cervical cancer, especially in the absence of a comprehensive cervical screening program (e.g. Hong Kong). Assessment of vaccine acceptability is important when evaluating the feasibility and cost-effectiveness of such vaccination programs. METHODS To provide a more representative and updated assessment on the acceptability of female adolescent HPV vaccination in Hong Kong, we conducted surveys in 2008 among 1022 mothers with daughters aged ≤ 18 years through random digit-dialing telephone interviewing and 2167 schoolgirls aged 11-18 years using two-stage stratified cluster sampling. We conducted the maternal survey again in 2012 with an independent group of 1005 mothers. RESULTS In 2008, 2.4% (95% confidence interval [CI]=1.8-3.2%) of the recruited schoolgirls reported having received HPV vaccination. In 2012, the mothers reported that 9.1% (7.0-11.6%) of their daughters who were in the same age range (11-18 years) as the schoolgirls had been vaccinated (p<0.01). Regarding acceptability, 27.5% (24.8-30.4%) and 37.6% (34.5-40.8%) of the mothers were willing to have their daughters vaccinated at market price in 2008 and 2012 (p<0.01), respectively. 27.1% (25.2-29.1%) of the schoolgirls were willing to receive HPV vaccination at market price in 2008. The willingness to pay for full-course vaccination among mothers had a median of US$128/HK$1000 (50% central range=US$64-192/HK$500-1500), i.e. substantially lower than the current market price. CONCLUSIONS The gap between acceptability and actual uptake of HPV vaccination among adolescent girls suggested that coverage is likely to be low without an organized HPV vaccination program, although the difference might be partially attributed to the possibility that at the time of the interview female adolescents who were willing to be vaccinated had not yet taken action. Policymakers should devise tailored, targeted and efficient vaccination strategies to achieve universal coverage for an effectively organized HPV vaccination program.

Abstract
STUDY OBJECTIVE Potential barriers between parents of children with special health needs (CSHCN) and their health care providers in regards to the patient receiving a full course of the human papillomavirus (HPV) immunization are explored in this study. STUDY DESIGN Parents of female CSHCN between ages of 9-26 years completed a questionnaire asking about personal receptivity of vaccines and potential barriers to vaccinating their child against HPV. A separate survey was completed by members of the Wisconsin and Illinois chapters of the American Academy of Pediatrics about HPV vaccination practices provided to patients with special health care needs. SETTING Outpatient urban health clinic and the Children's Hospital of Wisconsin's Adolescent Medicine and Neurology clinics from January 2009-2010. RESULTS Seventeen parents completed the survey. Forty-seven percent of parents answered that their child's pediatrician had offered the HPV vaccine; 17% reported that their child was vaccinated against HPV. Most parents knew that HPV is a sexually transmitted infection, causes genital warts, and can cause abnormal pap smears. For the provider survey, 77 out of 130 respondents offer HPV vaccine as part of their practice and see CSHCN. Ninety percent have vaccinated CSHCN against HPV. CONCLUSIONS This study suggests that acceptability of the HPV vaccine is high for health care providers, but acceptability in parents of CSHCN is lower than in the general population. This study raises awareness that health care providers need to be aware of the possibility that parents of CSHCN may not perceive their child as needing or being offered the HPV vaccine.
