Parental willingness to pay and preference for human papillomavirus vaccine for girls aged 9-14 in subsidy scenarios in Shanghai, China

Multiple studies have documented low human papillomavirus (HPV) vaccine uptake among Chinese girls. It remains crucial to determine the parental willingness to pay (WTP) HPV vaccine for girls. We conducted a cross-sectional study recruiting 3904 parents with girls aged 9-14 in Shanghai, China, employing an online questionnaire with a convenience sampling strategy. Parental WTP, both range of payment and estimated point value, were determined for themselves (or wives) and daughters. HPV vaccine uptake was 22.44% in mothers and 3.21% in daughters. Respondents favored WTP ≤ 1000 CNY/138 USD for themselves (or wives), whereas showed increasing WTP along with valency of HPV vaccine for daughters (2-valent: 68.62% ≤1000 CNY/138 USD; 4-valent: 56.27% 1001-2000 CNY/138-277 USD; 9-valent: 65.37% ≥2001 CNY/277 USD). Overall, respondents showed higher WTP for daughters (median 2000 CNY/277 USD; IQR 1000-3600 CNY/138-498 USD) than for themselves (2000 CNY/277 USD; 1000-3500 CNY/138-483 USD) or wives (2000 CNY/277 USD; 800-3000 CNY/110-414 USD) (each p < .05). Furthermore, parental WTP was higher for international vaccine and 9-valent vaccine (each p < 0.05). Between two assumed government subsidy scenarios, parental preference for 9-valent vaccine remained consistently high for daughters (approximately 24% in each scenario), whereas preference for themselves (or wives) was sensitive to payment change between the subsidy scenarios. Using a discrete choice experiment, we found domestic vaccine was commonly preferred; however, certain sociodemographic groups preferred multivalent HPV vaccines. In conclusion, the valency of HPV vaccine may influence parental decision-making for daughters, in addition to vaccine price. Our findings would facilitate tailoring the HPV immunization program in China.

Cervical cancer in Thailand: 2023 update

Cervical cancer continues to pose a challenge to the health of Thai women, as the second most common cancer after breast cancer. Since high-risk human papillomavirus (HPV) types are the main cause for cervical cancer, cervical cancer screening and HPV vaccination are necessary to reduce the incidence of this disease. At present, the World Health Organization hopes to reduce the incidence of cervical cancer to 4 or less cases per 100,000 women-years using 90%- 70%-90% intervention by 2030. The first intervention involves vaccinating 90% of women aged 15 years with the HPV vaccine. The second intervention involves screening 70% of women between the ages of 35 and 45 years using a high-performance screening test. The third intervention involves detecting cervical lesions in 90% of affected women to enable diagnosis and treatment. In this context, this study reviews trends in the incidence and mortality rates of cervical cancer in Thailand, in addition to providing an up-to-date overview of the causes and necessary risk factors for cervical cancer, as well as reporting on cervical screening and HPV vaccination rates and cervical cancer during the coronavirus disease 2019 (COVID-19) pandemic. This study may prove useful for the formulation of policy aimed at eliminating cervical cancer in Thailand, such as the implementation of a free HPV vaccine service and providing athome kits for cervical screening through clinics and pharmacies. In addition, this review also highlights the need for further research on the effects of the COVID-19 pandemic on cervical cancer screening rates in Thailand.

Human Papillomavirus Vaccination amongst Students in a Tertiary Institution in North Central Nigeria: A Cross-sectional Study on Sociodemographic Factors Associated with Its Awareness, Uptake and Willingness to Pay

BACKGROUND

Human papillomavirus (HPV) vaccine is effective in averting 70%-90% of all HPV-related diseases. The assessment of its awareness, uptake and willingness to pay (WTP) is important in Nigeria which is one of the developing countries where more than three-quarter of the global burden of HPV-related diseases occur. This study aimed to determine the sociodemographic factors associated with the awareness, uptake and WTP for HPV vaccine amongst undergraduates in a tertiary institution in North Central Nigeria.

METHODS

This was a cross-sectional study. Data were collected from randomly sampled respondents through a validated self-administered questionnaire. Descriptive statistics, Chi-square and logistic regression analyses were applied to data collected to determine the awareness, uptake and WTP for HPV vaccine and their association with sociodemographic factors. The results of inferential statistics were considered significant when P < 0.05.

RESULTS

A total of 240 respondents were recruited, 15.4% of the respondents had heard about HPV vaccine, 2.1% of them had received at least a dose of the vaccine, 0.4% of them had completed three doses and 35.0% of them were willing to pay for it. Marital status (adjusted odds ratio [AOR]: 10.2; 95% confidence interval [CI]: 2.840-36.635) and parity (AOR: 5.8; 95% CI: 2.314-14.565) were predictors of WTP for the HPV vaccine.

CONCLUSION

The evidence generated from this study suggests that there is a need to increase the awareness and uptake of the vaccine at the individual and population levels. The recent introduction of the HPV vaccine is a laudable step towards improving vaccine uptake. Public health authorities at the local, state and national levels should be empowered to develop tailored vaccine demand creation and advocacy strategies for HPV vaccine. Males should also be involved in the advocacy strategies and research on HPV vaccine.

On Imported and Domestic Human Papillomavirus Vaccines: Cognition, Attitude, and Willingness to Pay in Chinese Medical Students

This study aimed to analyze the cognition, attitude, and willingness to pay (WTP) for imported and domestic human papillomavirus (HPV) vaccines in Chinese medical students.

Acceptance and Willingness to Pay for Vaccine Against Human Papilloma Virus (HPV) Among Parents of Boys in Central Vietnam

Human papilloma virus (HPV) vaccine for adolescents was recommended as an effective prevention strategy of HPV-related cancers. In Vietnam, HPV vaccination has not been introduced to male adolescent. This study was conducted to examine the acceptance of having boys vaccinated against HPV and its underlying reasoning, and to identify their parent's willingness to pay (WTP) for HPV vaccination in central Vietnam. 785 parents of boys were directly interviewed based on a structured questionnaire. Parent's acceptability of HPV vaccine for their sons was identified by one question with response on 3-point scale (agree, don't know, and disagree). Multivariate logistic regression model was used to determine contributing factors to participant's acceptance. Bidding game method was applied to elicit WTP values for HPV vaccination with initial bid of 161.2 USD. The results showed that 49.2% of parents agreed to have their sons vaccinated against HPV. Factors that influenced parent's acceptance including son's age older than 12 years (OR = 1.5; 95% CI: 1.08–1.98); being eldest son (OR = 1.6; 95% CI: 1.13–2.19), being mother (OR = 1.4; 95% CI: 1.01–1.91), parents with high educational level (OR = 1.7; 95% CI: 1.11–2.47) and their knowledge of HPV and HPV vaccine (OR = 1.8; 95% CI: 1.23–2.65). Average WTP value for full doses of HPV vaccine was 137.5 USD, ranging between 9 USD and 188.3 USD. Parents' knowledge of HPV and HPV vaccine was the only factor affecting WTP value (Rho: 0.11; p-value: 0.030). The findings suggest a strategy be introduced for HPV vaccination to male adolescents in Vietnam.

Factors That Impact Acceptance of COVID-19 Vaccination in Different Community-Dwelling Populations in China

(1) Background: It is important to improve vaccination strategies and immunization programs to achieve herd immunity to infectious diseases. (2) Methods: To assess the acceptance of COVID-19 vaccination, we conducted face-to-face surveys and online surveys in Shanghai, Zhejiang, and Qinghai provinces. A fixed-effect model and a random effects model were used to analyze factors associated with the acceptance of COVID-19 vaccination. (3) Findings: We initially recruited 3173 participants, 3172 participants completed the full questionnaire (the response rate was nearly 100%), of which 2169 were valid questionnaires, with an effective rate of 87.3%. The results indicated that 82.6% of participants were willing to receive vaccination when it was available in the community, and 57.2% of deliverymen, 43.3% of medical workers, 78.2% of parents of primary and secondary school children, and 72.2% of parents of preschool children were willing to receive vaccination. The models showed that participants who were male (female vs. male: OR = 1.49, 95% CI (1.12, 1.98)), 60 to 69 years-old (60-69 vs. <30: OR = 0.52, 95% CI (0.29, 0.92)), had less education (medium vs. low: OR = 1.50, 95% CI (1.05, 2.23)), had good health status (good vs. low: OR = 0.36, 95% CI (0.15, 0.88)), and had positive attitudes and trust (OR = 0.14, 95% CI (0.10, 0.20)) in vaccines approved by the National Health Commission were more likely to accept vaccination. Participants also had an increased vaccination acceptance if it was recommended by government sources, doctors, relatives, or friends. Most participants learned about COVID-19 vaccination from television, radio, and newspapers, followed by community or hospital campaigns and the internet. (4) Conclusions: Government sources and doctors could increase the acceptance of vaccination by promoting the efficacy and safety of COVID-19 vaccination by the use of mass media and emphasizing the necessity of vaccination for everyone.

Knowledge, attitude and practice towards cervical cancer prevention among mothers of girls aged between 9 and 14 years: a cross sectional survey in Zimbabwe

Background

Cervical cancer (CC) morbidity and mortality is still high in developing countries like Zimbabwe. Treatment for CC is out of reach for many women, hence the need to maximise on prevention which mainly includes screening and administering human papillomavirus (HPV) vaccine. Knowledge about CC prevention is a prerequisite for utilisation of all the available options for CC prevention, yet little is known about its levels and the corresponding attitudes and practices on cancer prevention methods within the society.

Methods

A cross sectional survey was done to assess knowledge, attitude and practice (KAP) on CC prevention among mothers of girls aged between 9 and 14 years in Zimbabwe as well as factors explaining the KAP. Four hundred and six mothers participate. Descriptive and inferential statistics (binary logistic regression and Chi-Square test of association) were applied to determine participant characteristics with KAP using STATA version 16 software.

Findings

Overall KAP of cervical cancer prevention is in a poor state. The knowledge was poor with 24% being able to say CC is caused by HPV; the attitude is negative with 58% being of the opinion that CC is caused by witchcraft and it is a death sentence, while the bad practices of relying only on traditional means were being practiced. Factors associated with knowledge are: not having medical aid (odds: 0.17, 95%CI: 0.05–0.59, p = 0.005) and high levels of education (secondary level odds: 4.20; 95%CI: 2.25–7.84 p < 0.001 and tertiary odds: 7.75; 95%CI: 2.04–29.45, p-value: 0.003 compared to primary education). Attitude towards CC management was driven by levels of education (secondary level odds: 0.39, 95%CI: 0.20–0.78, p = 0.007 and tertiary odds: 0.12, 95%CI: 0.04–0.33, p < 0.001), the same factor increases odds of good practice (secondary odds: 3.78, 95%CI: 1.99–7.18, p < 0.001 and tertiary odds: 3.78, 95%CI: 1.99–7.18, p < 0.001). On the other hand, HPV vaccine knowledge was also very moderate (with majority of mothers not knowing the right age of vaccination; vaccine acceptability was high (90%), but uptake was very low (8% had their daughter vaccinated).

Conclusion

KAP about CC prevention was poor with factors necessary for improvement of KAP identified as education, medical insurance coverage. Making health education easily accessible in schools, primary health facilities and various media platforms will help to address the myths on causes of CC and how it can be treated. Health education and availability of free screening services and free vaccine will improve CC prevention out outcomes.

Willingness to pay for and acceptance of cervical cancer prevention methods: A systematic review and meta-analysis

Background: The Willingness to pay (WTP) for and acceptance of cervical cancer prevention (CCP) methods have an important role in the control of this type of cancer. Therefore, the aim of this study was to estimate the WTP and acceptance of CCP methods with the contingent valuation method (CVM). Methods: In this systematic review and meta-analysis study, the required information was collected by searching relevant keywords in PubMed, Scopus, Embase, Web of Knowledge, and their Persian equivalent in the Scientific Information Database (SID) and Elmnet databases during January 1, 2000 to June 30, 2020. All studies that reported the WTP and CCP methods with the CVM in English or Persian were included. The reporting quality of studies was assessed by strengthening the Reporting of Observational Studies in Epidemiology (STROBE). Comprehensive meta-analysis (CMA: 2) software was used to conduct the meta-analysis. The content analysis method was used for qualitative data analysis. Results: Finally, 28 articles (with 49610 people) were included in the study. Most of the participants were women (35.7%). The HPV vaccine was the most common method of prevention (75%). The overall acceptance rate was 64% and the overall positive WTP rate was 66%. The average WTP was US$30.44, which accounts for about 0.84% of GDP per capita. The most significant effective factors included income, age, education, high-risk sexual behaviors, and awareness of cervical cancer, belief in the risk of cervical cancer, and belief about the effectiveness of prevention methods. The cost was the most important reason for the unwillingness to pay and accept. Conclusion: Results show that the WTP and acceptance rate of CCP methods are relatively high. It is recommended to reduce the cost of prevention methods, especially the HPV vaccine, and to increase awareness and improve the attitude of people. Also, it is recommended to consider other methods of estimation of WTP and other cancers in future studies.

Awareness, acceptability and uptake of cervical cancer vaccination services among female secondary school teachers in Enugu, Nigeria: a cross-sectional study

INTRODUCTION

cervical cancer is a major cause of morbidity and mortality in women and vaccination of adolescents with human papilloma virus (HPV) vaccines is a major preventive strategy for this cancer. Despite the usefulness of cervical cancer vaccines, significant gaps still exist in the level of awareness and acceptability of the vaccine among women. This study aimed to determine the level of awareness, acceptability, and identify the factors associated with the uptake of this vaccine by female secondary school teachers in Enugu, Nigeria.

METHODS

a cross-sectional study of 377 female teachers in Enugu metropolis was undertaken between July and October 2017. A structured interviewer-administered pretested questionnaire was used for data collection and SPSS used for analysis.

RESULTS

less than half (41.9%) of the respondents had good knowledge of the cervical cancer vaccine. The majority of the respondents (93.6%) accepted the vaccine and will recommend it for their children and students. Only 14.6% and 9.0% of the respondents have taught their students about cervical cancer or HPV vaccines and had a programme in their school that addresses cervical cancer or cervical cancer vaccination respectively. Only 3.4% of the respondents have been vaccinated while 5.6% of their children or relatives have received the HPV vaccine. Previous vaccination of participants (p = 0.000), existing programmes addressing cervical cancer in schools of respondents (p = 0.000), participants having taught students about cervical cancer (p = 0.025) and high economic status (p = 0.013) significantly increased the likelihood of participants vaccinating their adolescent daughters/relatives. Extremes of age (p = 0.001) and being the head of their families (p = 0.002) significantly reduced the likelihood of the daughters/relatives to be vaccinated. Only previous history of vaccination of the respondents predicted the vaccination of their children and relatives (AOR = 6.069; 95% CI; < 0.0001-0.041).

CONCLUSION

the overall knowledge of the HPV vaccine was low but the acceptability was high among respondents who were aware of the vaccines. Vaccine uptake among children/family members of the respondents was low. The introduction of cervical cancer vaccination education of the teachers in the secondary schools will help improve cervical cancer vaccination and the uptake among adolescent´s populations in the country.

A New Strategy for Cervical Cancer Prevention Among Chinese Women: How Much Do They Know and How Do They React Toward the HPV Immunization?

In 2017, HPV vaccines were first marketed in China. We carried out an investigation among parents of high school students to assess parents' knowledge of cervical cancer and human papillomavirus (HPV)/HPV vaccines, along with their acceptance of HPV vaccination and the factors that influence it, all of which are essential for targeted education regarding HPV vaccination. A cross-sectional study was conducted among parents of high school students in East China using a pretested questionnaire. Data regarding knowledge of cervical cancer, HPV, HPV vaccines, and acceptance of the vaccines were collected and analyzed. In total, 1,200 questionnaires were distributed, with 1,125 valid responses. Overall, 87.5% of respondents knew that cervical cancer is one of the most common genital system cancers; 78.67% knew that HPV causes cervical cancer; 69.2% knew that HPV is primarily transmitted through sex; 54.3% knew that HPV vaccines exist; and 35.6% knew the optimal age for HPV vaccination. Only 4.4% had vaccinated their daughters for HPV, and 35.4% were willing to do so. Reasons for refusal primarily concerned the vaccines' safety (77.4%) and efficacy (61.5%). Multivariate analyses showed that parents who had obtained pneumococcal conjugate vaccines for their daughters showed higher acceptance of HPV vaccines, as well as higher knowledge of cervical cancer, the association of HPV and cervical cancer, and the main transmission route of HPV. Although parents' knowledge level regarding cervical cancer was moderate, it was very low regarding HPV and HPV vaccines. Teenagers' HPV vaccine uptake and parents' willingness to vaccinate their children was also quite low. Educational interventions and awareness campaigns are needed to ensure the success of HPV immunization programs in East China.

Parents' knowledge, beliefs, acceptance and uptake of the HPV vaccine in members of The Association of Southeast Asian Nations (ASEAN): A systematic review of quantitative and qualitative studies

BACKGROUND AND OBJECTIVE

Cervical cancer is the second most common malignancy affecting females in Southeast Asia. Human Papillomavirus (HPV) vaccines have been available since 2006. Several Association of Southeast Asian Nations (ASEAN) member countries have since introduced and/or piloted the HPV vaccine with adolescent females. This systematic review was conducted to understand what factors influence parents' acceptance of the HPV vaccine in the region.

METHODS

Seven databases were searched for qualitative and quantitative studies published up to 16 April 2020. Papers were included if they were peer-reviewed, in English, available in full text, and had a focus on parents' knowledge, beliefs, attitudes and acceptance of the HPV vaccine. Findings were integrated to answer the review question using framework analysis based on the Theory of Planned Behaviour.

RESULTS

Sixteen publications were included and synthesised under the Theory of Planned Behaviour domains: 1) Knowledge, attitudes and acceptance, 2) subjective norms, and 3) perceived behavioural control. Parents' attitudes to HPV vaccination were positive and acceptance to vaccinate their daughters against HPV was high. The uptake was high when the vaccine was offered for free.

CONCLUSION

Parents' acceptance and uptake of the HPV vaccine in ASEAN member-countries was high when the vaccine was offered for free even though their knowledge of cervical cancer and HPV was poor. Further research is needed to see how uptake and acceptance can be maintain when the vaccine is not offered for free.

The epidemiologic and economic impact of a quadrivalent human papillomavirus vaccine in Thailand

BACKGROUND

The human papillomavirus (HPV) vaccine was introduced into Thailand's national immunization program in 2017 for 11-12 year old school girls. The objectives of this study were to examine the epidemiological consequences and cost-effectiveness of a routine quadrivalent HPV (4vHPV) vaccination and the routine 4vHPV vaccination plus 5-year catch-up vaccination by comparing with cervical cancer screening only (no vaccination) in Thailand.

METHOD

A transmission dynamic model was used to assess the cost-effectiveness of the routine 4vHPV vaccination and the routine 4vHPV vaccination plus catch-up vaccination, compared with no vaccination (screening only) in Thai population. The vaccination coverage rate assumptions were 95% in 11-12-year-old girls for the routine vaccination and 70% in 13-24 year-old females for the 5-year catch-up vaccination. Vaccination costs, direct medical costs of HPV-related diseases, and the number of quality of life years (QALYs) gained were calculated for over a 100-year time horizon with discount rate of 3%.

RESULT

The model indicated that the routine 4vHPV vaccination and the routine plus catch-up 4vHPV vaccination strategies could prevent approximately 434,130 and 472,502 cumulative cases of cervical cancer, 182,234 and 199,068 cumulative deaths from cervical cancer and 12,708,349 and 13,641,398 cumulative cases of HPV 6/11 related genital warts, respectively, when compared with no vaccination over 100 years. The estimated cost per QALY gained (ICER) when compared to no vaccination in Thailand was 8,370 THB/QALY for the routine vaccination and 9,650 THB/QALY for the routine with catch-up vaccination strategy.

CONCLUSION

Considering the recommended threshold of 160,000 THB/QALY for Thailand, the implementation of the routine 4vHPV vaccination either alone or plus the catch-up vaccination was cost-effective as compared to the cervical cancer screening only.

Knowledge of Cervical Cancer and Human Papillomavirus Vaccines among Child-Bearing Aged Women in Hanoi, Vietnam

Objectives:

The study sought to examine knowledge of cervical cancer and human papillomavirus (HPV) vaccines among child-bearing aged women in Hanoi, Vietnam.

Methods:

In 2016, 807 women aged 18 to 49 years were recruited from one urban area and one rural area in 2016 and were examined through face-to-face paper-based interviews. Pearson’s chi-square test and an independent t-test were utilized to compare awareness of cervical cancer and HPV vaccination among women according residential status.

Results:

Overall, 83.8% and 71.3% women had heard about cervical cancer and HPV vaccination, respectively. Mean knowledge scores for cervical cancer and HPV vaccination were 4.60±1.43 out of 7 and 1.53±1.35 out of 5, respectively. Women living in an urban area were more likely to be aware of cervical cancer and to be more knowledgeable of HPV vaccination than women in a rural area.

Conclusions:

Despite strong awareness, we found knowledge on cervical cancer and HPV vaccination to be alarmingly insufficient among Vietnamese women.

Intention to Pay for HPV Vaccination among Women of Childbearing Age in Vietnam

The intention to pay for human papillomavirus (HPV) vaccination among women of childbearing age in Vietnam, where cervical cancer remains a significant public health concern, has been mostly lacking. To examine this issue, we conducted a cross-sectional study of 807 pregnant women in an urban and a rural district (Dong Da and Ba Vi) of Hanoi, Vietnam. The vast percentage of our respondents expressed a firm intention to vaccinate, especially women in rural areas (over 90.0%). However, on being informed of the current price of the HPV vaccine, their intention to vaccinate dropped to about one-fifth of overall respondents, i.e., only 4.4% of women in rural areas. It was also observed that the initial intention to get the HPV vaccination among women in the rural district was about ten times higher than that of women living in the metropolitan district. Those participants who had greater knowledge of cervical cancer and HPV vaccinations also had a significantly higher intention to vaccinate. Our findings underscore the need to develop a well-designed vaccination program in Vietnam and other countries in a similar situation to increase the adoption of HPV vaccination.

HPV VACCINE ADHERENCE AMONG ADOLESCENTS: INTEGRATIVE REVIEW

ABSTRACT Objective: to identify what factors are connected to adolescent adherence to the vaccination against Human Papillomavirus. Method: integrative developed using the following data base: Medical Literature Analysis and Retrieval System Online and Web of Science, Cumulative Index to Nursing and Allied Health Literature, Literatura Latino-Americana e do Caribe em Ciências da Saúde (Latin-American and Caribbean Literature in Health Sciences), and Base de dados de Enfermagem (Nursing Database); using the descriptors and keywords: Papillomaviridae, immunization, vaccines. The final sample had 31 original articles. Result: Vaccine adherence predictors were identified as: knowledge about virus infection risk, vaccination and its benefits; cervical cancer and genital warts prevention; sexual activity; being over 14 years old; mothers’ intention to adhere to vaccination; mother-child communication about sexually transmitted infections, contraception and condoms; vaccination offered in school; recommendation by teachers and health professionals; vaccine safety and effectiveness. Conclusion: Evidence points towards the necessity to redesign the presentation strategy of the vaccine, because despite the cultural differences among the countries where the studies were carried out, it is noticeable that society shelters adolescents aged from 10 to 14 years old, considering it early for sexual initiation and presenting difficulties to broach sexuality-related topics with children.

Knowledge, Perception, and Acceptance of HPV Vaccination and Screening for Cervical Cancer among Women in Yogyakarta Province, Indonesia

Objective:

To determine knowledge, perception, and acceptance related to cervical cancer, HPV vaccination and screening for cervical cancer among Indonesian women, particularly in Yogyakarta province.

Methods:

A convenience sample of 392 women consists of 192 young women, 100 mothers of girls aged 12 – 15 years, and 100 adult women in Yogyakarta province, Indonesia was participated in this study. A self-administered paper-based questionnaire was used to determine demographics characteristics of respondents, as well as their knowledge – perception – acceptance related to cervical cancer, HPV vaccination, and screening for cervical cancer. Data collection were conducted during December 2013 to March 2014. Descriptive statistics was used to analyze description of demographics characteristics, knowledge, perception, and acceptance; while crosstab analysis using Chi-Square was used to analyze the relationship between demographics characteristics versus knowledge, perception, and acceptance.

Results:

This study found that knowledge and perception regarding cervical cancer, HPV vaccination, and screening for cervical cancer among women in Indonesia, particularly in Yogyakarta Province were still insufficient, however the acceptance was good. Among female young women, 64% had good knowledge, 62% had positive perception of cervical cancer and HPV vaccination, and 92% tended to accept HPV vaccination. Among mothers of girls aged 12 – 15 years, 44% had good knowledge, 46% had positive perception of cervical cancer and HPV vaccination, and 91% tended to accept HPV vaccination for their daughters. Among adult women, 68% had good knowledge, 57% had positive perception of cervical cancer and screening for cervical cancer, and 90% tended to accept cervical cancer screening. In general, demographics characteristics of having experience and exposure to information had significant relationship with knowledge, perception, and acceptance of HPV vaccination and screening for cervical cancer.

Conclusions:

Either knowledge or perception of cervical cancer and strategies toward it among Indonesian women particularly in Yogyakarta province were still unsatisfied. Efforts should be improved for supporting cervical cancer prevention and control in Indonesia through such as education on cervical cancer disease and strategies toward it.

Factors influencing intention to obtain the HPV vaccine in South East Asian and Western Pacific regions: A systematic review and meta-analysis

Since licensing in 2006, there has been poor uptake of the HPV vaccine among the targeted population in the South East Asia Region (SEAR) and Western Pacific Region (WPR). A systematic review was conducted to identify the studies exploring the relationship between factors and intention for HPV vaccination among women in SEAR and WPR countries. Nineteen studies were identified as suitable for qualitative synthesis, and three as suitable for meta-analysis. Most women had a positive intention to have an HPV vaccine (range 57%-85%). Having a positive intention to vaccinate was significantly higher among women not aware of HPV infection (OR: 1.34, 95% CI: 1.02-1.76) and HPV vaccine (OR: 1.57, 95% CI: 1.26-1.96). Lower knowledge level and less confidence in safety and efficacy of the vaccine, negatively affected intention to vaccinate. Perceiving the vaccine to be expensive, low perception of contracting HPV infection and cervical cancer, and lack of concrete recommendations from healthcare providers also negatively affected intention to vaccinate. This review suggests the decision-making processes of women in SEAR and WPR is influenced by the cost of vaccination, perceived efficacy and safety of vaccine, provision of information on vaccination, and the awareness about HPV infection and the HPV vaccine.

Willingness to pay for an Ebola vaccine during the 2014-2016 ebola outbreak in West Africa: Results from a U.S. National sample

The 2014-2016 Ebola virus outbreak in West Africa led to advances in the development of vaccines against Ebola. This study examined factors associated with willingness to pay for an Ebola vaccine among a U.S. national sample during the recent Ebola outbreak. From April 30-May 8, 2015, a national survey was conducted using the GfK Group's KnowlegePanel®. Main outcome measures included willingness to pay at least $1; more than $50; and more than $100 for an Ebola vaccine. Analyses were conducted using weighted multivariable logistic regression. Among participants (N = 1,447), 583 (40.3%) would not pay for an Ebola vaccine; 864 (59.7%) would pay at least $1. Among those willing to pay at least $1: 570 (66.0%) would pay $1-50; 174 (20.1%) would pay $51-100; and 120 (13.9%) would pay more than $100. Willingness to pay at least $1 for an Ebola vaccine was associated with international travel; interest in getting an Ebola vaccine; and beliefs that the U.S. government should spend money to control Ebola and assume worldwide leadership in confronting emerging epidemics. Willingness to pay more than $50 was associated with similar variables. Willingness to pay more than $100 was associated with international travel; interest in getting an Ebola vaccine; information seeking; and beliefs that the U.S. government should assume worldwide leadership in confronting emerging epidemics. International travel and interest in an Ebola vaccine were key predictors of willingness to pay across all price points. Understanding willingness to pay for vaccines against emerging infectious diseases remains critical.

Factors involved in human papillomavirus (HPV) vaccine hesitancy among women in the South-East Asian Region (SEAR) and Western Pacific Region (WPR): A scoping review

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.

Knowledge about Human Papillomavirus and Cervical Cancer: Predictors of HPV Vaccination among Dental Students

Background: The objective of this study is to determine the influence of dental students’ knowledge and attitude regarding human papillomavirus infection of cervical cancer on willingness to pay for vaccination. Basic research design: A convenience sampling method was used. The minimal sample size of 136 was calculated using the Raosoft calculator with a 5 % margin of error and 95% confidence level. Participants: The study population were all final year dental students from the School of Dentistry. Methods: A self-administered questionnaire was used to measure knowledge levels and attitudes regarding human papillomavirus vaccination. Contingent valuation was conducted for willingness to pay for vaccination. Main outcome measures: The Center for Disease Control and Prevention has stated that human papillomavirus are associated with oropharynx cancer and the American Dental Association insist on expanding public awareness of the oncogenic potential of some HPV infections. Thus, as future dental practitioners, dental students should be aware of human papillomavirus and their links with cancer and the benefits of vaccination. Results: Knowledge on HPV and cervical cancer did not impact on attitudes towards vaccines. However, significant correlation existed between knowledge and willingness to pay for vaccination. Conclusions: Dental students’ knowledge on HPV and cervical cancer has no influence on their attitude towards HPV vaccines. However, their willingness to pay for HPV vaccination is influenced by their knowledge of cervical cancer and HPV vaccination.

Knowledge of Human Papillomavirus Infection, Cervical Cancer and Willingness to pay for Cervical Cancer Vaccination among Ethnically Diverse Medical Students in Malaysia

The primary objective of this study was to assess the knowledge of medical students and determine variation between different cultural groups. A secondary aim was to find out the willingness to pay for cervical cancer vaccination and the relationships between knowledge and attitudes towards Human Papillomavirus vaccination. A cross-sectional survey was conducted in a private medical university between June 2014 and November 2014 using a convenient sampling method. A total of 305 respondents were recruited and interviewed with standard questionnaires for assessment of knowledge, attitudes and practice towards human papilloma virus and their willingness to pay for HPV vaccination. Knowledge regarding human papilloma virus, human papilloma virus vaccination, cervical cancer screening and cervical cancer risk factors was good. Across the sample, a majority (90%) of the pupils demonstrated a high degree of knowledge about cervical cancer and its vaccination. There were no significant differences between ethnicity and the participants' overall knowledge of HPV infection, Pap smear and cervical cancer vaccination. Some 88% of participants answered that HPV vaccine can prevent cervical cancer, while 81.5% of medical students said they would recommend HPV vaccination to the public although fewer expressed an intention to receive vaccination for themselves.

Parents' preferences and willingness-to-pay for human papilloma virus vaccines in Thailand

Objective

To examine parents’ preferences and willingness-to-pay (WTP) for HPV vaccines.

Methods

A discrete choice experiment (DCE) was used. Parents with at least one daughter aged 9–13 years residing in Songkhla province were asked to choose one alternative from each DCE choice set describing HPV vaccines by four attributes, including cervical cancer risk reduction, genital warts risk reduction, common side effects, and cost. Multinomial logit model was used for data analyses.

Results

Parents preferred higher risk reductions for cervical cancer and genital warts, and lower common side effects. They valued the quadrivalent and bivalent HPV vaccines at 21,189.9 and 10,479.9 Baht, respectively. Results also showed that mothers valued both vaccines more than fathers did.

Conclusions

Parents valued net benefits for both quadrivalent and bivalent HPV vaccines, but they were willing to pay for the quadrivalent vaccine more than for the bivalent vaccine.

Knowledge, attitudes and behaviors of women over 20 years old on cervix cancer in Istanbul, Turkey

PURPOSE

The aim of the study was to evaluate knowledge, attitudes and behaviors of Turkish women over 20 years old on cervix cancer.

MATERIALS AND METHODS

This descriptive study was performed at a primary care center covering 246 women using a questionnaire composed of 3 sections and 38 questions. The data were analyzed using descriptive statistics, chi-square test in univariate analysis and multivariate hierarchical logistic regression analysis.

RESULTS

Of the 93.7% women who knew about cervical cancer, 68.0% of them had heard pap smear test and 46.1% had actually undergone a Pap smear once or more throughout their lives. According to the results of the hierarchical logistic regression analysis about factors affecting the Pap smear test; in Model 1, increase in age and education levels, in Model 2 and Model 3 increase in age and cervical cancer information points were determined. The most important information source for cervical cancer was TV-radio/media (59.9%) and health care workers (62.8%) for pap smear test.

CONCLUSIONS

Although most women have heard of cervical cancer, knowledge about cervical cancer and also Pap smear screening rate are significantly lower. Having Pap smear test for women was affected by age and knowledge level about cervical cancer. Informing women about cervical cancer would be an important intervention.

Mothers' knowledge and attitudes about HPV vaccination to prevent cervical cancers

BACKGROUND

Cervical cancer which is one of the most preventable cancers is an important public health problem worldwide, and especially in developing countries. The aim of this study was to determine knowledge and attitudes about the HPV vaccination of mothers with 0- to 18-year old children.

MATERIALS AND METHODS

Written approval was taken from the local authorities. The study subjects consisted of 799 mothers who agreed to participate. The data were collected via a "Personal Information Form" which included 30 questions that were prepared by the researchers themselves in line with the literature. The data were collected by face to face interviews with the mothers. Analyses were performed using commercial software.

RESULTS

The mean age of the mothers who participated in the study was 32.0 ± 6.52, and 88.1% reported no information about HPV, and 83.5% no information about HPV vaccination. Only 0.7% of the mothers had daughters who had HPV vaccination, and 44.3% of the mothers who had sons were found out to be indecisive about having HPV vaccination. There was a significant corelation between the educational status of the mothers and their knowledge about HPV vaccination (p<0.05). However, there was no significant correlation in terms of economic conditions (p>0.05).

CONCLUSIONS

This study suggested that mothers had very little information on HPV and HPV vaccination. Knowledge of the disease and its vaccination is an essential factor for the success of the vaccination program. It is of great importance that mothers are trained in this subject by health professionals.
