Knowledge and Attitudes About HPV Infection, HPV Vaccination, and Cervical Cancer Among Rural Southeast Asian Women

Factors related to cervical cancer and human papilloma virus awareness among rural women of southern Bangladesh: A cross-sectional study

Introduction

Cervical cancer is an important public health issue in Bangladesh. Despite government efforts, the awareness and healthcare utilization in rural areas are inadequate.

Methodology

This cross-sectional study was conducted in six districts of Barishal division over 997 respondents aged 15-64 years. The demographic variables, accessibility to healthcare, vaccination status, awareness of HPV causing cervical cancer, and knowledge of the HPV vaccine were recorded through a structured questionnaire. T-test for univariate and chi-square test for bi-variate analysis were used. Logistic regression was used to determine factors associated with awareness.

Results

Most of the participants were SSC passed (45.3%), unemployed (54.4%), and married (74.4%). While 83.5% were aware of cervical cancer, only 3.3% knew about HPV's role. The majority (96.2%) had never been tested for HPV, albeit 79.5% knew about the vaccine, and only 2.45% were vaccinated. Knowledge levels were low, with only 1.4% demonstrating sound knowledge, mostly associating with higher income, residing closer to healthcare facilities, and being married. Bhola district participants had highest level of awareness, and the lowest was in Pirojpur. Education level was positively correlated with knowledge, with graduates being most aware. Logistic regression showed education, marital status, willingness to vaccinate daughters, and district were significantly related with better awareness, while income, distance, and age did not.

Conclusion

Mass education and awareness campaigns may improve the awareness level in rural community.

Knowledge and Practices Regarding Human Papillomavirus and Cervical Cancer Screening Among Women in Low-Income Areas of China: A Cross-Sectional Study

BACKGROUND

Persistent human papillomavirus (HPV) infection is the primary cause of cervical cancer. However, this can be prevented through vaccination and screening. This study aimed to clarify the relationship between behavior, knowledge, and attitude toward cervical cancer and regular screening and HPV infection among women in Lueyang County.

METHODS

Women who underwent cervical cancer screening at the outpatient department of a maternal and child health center between September and December 2021 were invited to participate. In total, 2,303 women completed the questionnaire. Women who underwent regular or irregular screening were 1:1 matched for age. Differences in knowledge of HPV and attitudes toward HPV vaccination among different populations were assessed. Logistic regression analysis was performed to identify the factors influencing HPV infection.

RESULTS

 In total, 417 pairs of women who underwent regular and irregular screening were successfully matched. Multivariate logistic regression results indicated that age is a risk factor for HPV infection (OR=1.056 95%CI: [1.031 1.082]), while regular screening acts as a protective factor against HPV infection (OR=0.174 95%CI: [0.117 0.259]). Additionally, regular screening was associated with a higher level of knowledge about HPV among women compared to those who did not undergo regular screening (p<0.001).

CONCLUSIONS

 Women in Lueyang County have low levels of knowledge regarding HPV and cervical cancer. Regular screening is a protective factor against HPV infection. The regular screening group demonstrates a higher level of HPV knowledge compared with the irregular screening group. These findings highlight the importance of regular screening and the need to strengthen public health education.

Cervical Cancer Prevention in Rural Areas

Objective

Globally, cervical cancer (CC) incidence is higher in rural areas than in urban areas that could be explained by the influence of many factors, including inequity in accessibility of the CC prevention measures. This review aimed to identify and analyze factors associated with a lack of cervical cancer screening and HPV vaccination programs in people living in rural areas and to outline strategies to mitigate these factors.

Methods

The literature search encompassed two focal domains: cervical cancer screening and HPV vaccination among populations residing in rural areas, covering publications between January 1, 2004 to December 31, 2021 in the PubMed, Google Scholar, Scopus, and Cyberleninka databases, available in both English and Russian languages.

Result

A literature review identified 22 sources on cervical cancer screening and HPV vaccination in rural and remote areas. These sources revealed similar obstacles to screening and vaccination in both high and low-income countries, such as low awareness and knowledge about CC, screening, and HPV vaccination among rural residents; limited accessibility due to remoteness and dearth of medical facilities and practitioners, associated with a decrease in recommendations from them, and financial constraints, necessitating out-of-pocket expenses. The reviewed sources analyzed strategies to mitigate the outlined challenges. Possible solutions include the introduction of tailored screening and vaccination campaigns designed for residents of rural and remote locations. New screening and vaccination sites have been proposed to overcome geographic barriers. Integrating HPV testing-based CC screening is suggested to counter the lack of healthcare personnel. HPV vaccination is essential for primary cervical cancer prevention, especially in rural and remote areas, as it requires less medical infrastructure.

Conclusion

Certain measures can be proposed to improve the uptake of CC screening and HPV vaccination programs among rural residents, which are needed to address the higher prevalence of CC in rural areas. Further investigation into cervical cancer prevention in rural and remote contexts is necessary to ascertain the optimal strategies that promote health equity.

The Role of Health Information Technology in Improving Awareness of Human Papillomavirus and Human Papillomavirus Vaccine Among U.S. Adults

Objective: Although human papillomavirus (HPV) vaccines prevent cancer-causing HPV infections and cervical precancers, there is suboptimal awareness and limited global accessibility of HPV and HPV vaccine. Emerging evidence suggests that health information technology (HIT) may influence HPV-related awareness and improve vaccine adoption. The objective of this study was to evaluate the link between HIT and HPV-related awareness Methods: Data were obtained from 1,866 U.S. adults aged 18-45 years who completed the 2017 and 2018 Health Information National Trends Survey. We conducted multivariable logistic regression to analyze the association between HIT utilization and HPV-related awareness. Results: Awareness of HPV and HPV vaccine were 72.7% and 67.5%, respectively. Participants who used electronic means to look up health information (adjusted odds ratio [aOR] = 3.05; p = 0.001), communicate with health care provider (aOR = 1.68; p = 0.026), look up test results (aOR = 1.94; p = 0.005), and track health costs (aOR = 1.65; p = 0.04) were more likely to report HPV awareness than those who did not. Participants who used an electronic device to look up health information (aOR = 3.10; p = 0.003), communicate with clinicians (aOR = 1.72; p = 0.008), look up test results (aOR = 1.63; p = 0.021), and track health care charges (aOR = 1.90; p = 0.006) were more likely to report HPV vaccine awareness than those who did not. Discussion and Conclusion: Our findings suggest a positive association between HIT utilization and HPV-related awareness. Given the rapid and exponential increase in mobile technology access globally, these results are encouraging and offer a potential opportunity to leverage digital technology in primary cancer prevention for HPV-related cancers, especially in low- and middle-income countries with unsophisticated health infrastructures.

HPV vaccine intention among university students during suspension of active recommendation in Japan

In Japan, active recommendation of the human papillomavirus vaccine was withheld between 2013 and 2021 due to adverse reaction reports. This resulted in low vaccine coverage with reports from less than 1%. This study aimed to investigate if knowledge and health-belief related factors associated with vaccine intention among young adolescents with the hope that our findings may be helpful in promotion campaigns. We recruited students in four colleges and universities in Akita Prefecture from 2020 to 2021 who had never been vaccinated. A total of 318 students (male 54%, mean age 21 years) responded to a self-administered questionnaire; only 6% reported immediate vaccine intention, and 61% reported no such intention or "do not know." The correct percentages of 20-item knowledge about HPV vaccine-related morbidity, mortality, and prevention were very low regardless of gender (average males 41.4% vs. females 39.6%). Multivariable logistic regression models demonstrated that in males, higher levels of literacy, perceived susceptibility, and place for vaccination (logistical barrier) were associated with HPV vaccine intention, whereas "no need now" was associated with less intention. In females, a higher level of knowledge was significantly associated with vaccine intention, whereas "concerns of adverse effects" were associated with less intention.

Influence of LINE-Assisted Provision of Information about Human Papillomavirus and Cervical Cancer Prevention on HPV Vaccine Intention: A Randomized Controlled Trial

We conducted a prospective, randomized two-arm, parallel group, and open label trial to investigate whether the use of LINE would increase HPV vaccine intention among not completely vaccinated university students. In June 2020, we recruited students aged between 18 and 35 years from four universities in Japan. Among the 357 enrollees (female, 53%), 178 and 179 participants were randomized into the LINE and Mail groups, respectively. At baseline, within three years, vaccine intention was observed in 40% vs. 42% of participants, respectively. At the first intervention, which provided similar PDF leaflets about HPV vaccine and cervical cancer prevention, there was no significant difference in vaccine intention between the two groups. However, at the second intervention of LINE-assisted knowledge intervention for 5 days per week for 7 weeks, the LINE group had a higher proportion of vaccine intention than the no intervention group (66% vs. 44%, OR: 2.62, 95% confidence interval (CI): 1.59-4.35) in per-protocol analysis. The significance remained in the intention-to-treat analysis of multiply imputed datasets. Although LINE did not directly increase HPV vaccine intention compared to conventional posts, the LINE-assisted provision of information was effective in improving HPV vaccine intention among Japanese university and college students.

Strategies to improve the vaccine distribution and community awareness of taking COVID-19 vaccine in rural areas in Indonesia

COVID-19 has spread worldwide, and several governments, including Indonesia, are actively vaccinating. However, numerous factors may contribute to decreased vaccination administration, including hesitation, a lack of information, and demographic considerations. Therefore, this review provides insights on maximizing vaccine distribution and raising community awareness about COVID-19 vaccination in rural regions with difficulty in transportation access, a lack of health care workers, and limited vaccine storage facilities. It was discovered that numerous potential methods, such as the Internet of Things (IoT), bio-tracking and bio-detect, P-median, and Vehicle Routing Problem (VRP), can monitor vaccination delivery in rural parts of Indonesia. The correct vaccine distribution system can monitor situations during distribution by combining IoT technology with bio-tracking and bio-detect in airborne transportation. Besides enhancing vaccine distribution technologies, healthcare professionals play a critical role in maintaining vaccine quality and improving community awareness of diseases. In particular, as a healthcare professional, a pharmacist has an essential role in ensuring the quality of the vaccine until it is administered to the patient and improving patients’ awareness of COVID-19 and the vaccinations. Pharmacists can collaborate with other healthcare professionals to educate the community to identify important information related to wrong perceptions about COVID-19 and vaccinations.

Investigating Bangladeshi Rural Women's Awareness and Knowledge of Cervical Cancer and Attitude Towards HPV Vaccination: a Community-Based Cross-Sectional Analysis

Cervical cancer remains a significant disease burden and contributes to prominent cancer-related mortality among women. This study aimed to assess awareness and knowledge of cervical cancer and attitude towards HPV vaccination among rural women in Bangladesh. A cross-sectional study was carried out from September 2019 to January 2020 involving 600 women selected using multi-stage sampling from six rural areas of Bangladesh. Face-to-face interviews were conducted using a semi-structured questionnaire consisting of socio-demographic information, knowledge (20-items) and, attitudes (5-items). Most of the participants (71.8%) were aware of cervical cancer. Women's awareness was significantly associated with marital status, education level, employment status, and internet/social media use (p < 0.05). Mass media was the main source of information and 2.3% of the women had previously undergone cervical cancer screening. Knowledge regarding symptoms, risk factors, and preventive measures was limited with a mean knowledge score of 8.73 (SD: 2.68). Only 5.3% of women had vaccinated against HPV, but the willingness to receive the HPV vaccine was high (76.6%) among those who were not vaccinated. The cost of the HPV vaccine (40.1%) and lack of adequate knowledge (34.3%) were the main reasons behind women's unwillingness to receive the vaccine. Higher odds of willingness to receive the HPV vaccine were found among women aged 15-29 years (aOR: 1.92, CI = 1.21-3.04, p = 0.006), had high education (aOR: 1.93, CI = 1.25-4.42, p = 0.005), and internet/social media users (aOR: 2.32, CI: 1.51-3.56, p < 0.001). These results highlight the urgent need for educational intervention on cervical cancer and the institution of national policies providing HPV vaccination coverage.

Knowledge and attitude regarding cervical cancer and its prevention among young female adults in Kuantan, Malaysia

BACKGROUND

Cervical cancer is the second-most common female cancer in Malaysia after breast cancer. This study intended to investigate the knowledge and attitude regarding cervical cancer and its prevention and its associated factors among young female adults in Kuantan, Malaysia, to gauge the community's understanding and idea about this issue.

MATERIALS AND METHODS

The study was conducted in attractive places in Kuantan, Malaysia, such as shopping malls and Urban Transformation Centre, using a cross-sectional study design and convenience sampling method. Data on the respondents' knowledge and attitude regarding cervical cancer and its prevention were collected using a questionnaire. Kruskal-Wallis, Independent t-, and Pearson correlation tests were used to investigate the study variables' association using SPSS software.

RESULTS

From the total of 142 respondents, almost half of them aged between 20 and 24 years old with the majority were Malays (85.9%) and single (74.6%). The internet (78.1%) was identified as the main medium to gain information regarding cervical cancer. The results show that levels of education, races, and occupation types were statistically significantly associated with the respondents' knowledge and attitude scores in this study. Age was found to be associated with knowledge scores only, while marital status was only significantly associated with the attitude scores regarding cervical cancer and its prevention. Knowledge scores were also found to be positively associated with attitude scores.

CONCLUSION

Several socio-demographic factors were significantly associated with the knowledge and attitude regarding cervical cancer and its prevention. In view of the positive association between knowledge and attitude scores, suitable health promotion activities can be designed and planned to increase young female adults' knowledge and attitudes toward cervical cancer and its prevention.

Trends in cervical cancer mortality in China from 1989 to 2018: an age-period-cohort study and Joinpoint analysis

Background

Worldwide, cervical cancer is the second-most-common malignancy of the female reproductive system. Due to its large population, China accounted for 11.9% of cervical cancer deaths, and 12.3% of global cervical cancer DALYs in 2017. In 2009, China launched a nationwide screening program, yet mortality from cervical cancer has shown an upward trend in recent years. The aim of this study was to explore factors affecting cervical cancer mortality rates in China, and contribute to their future reduction.

Methods

In this descriptive study, a Joinpoint regression analysis and age-period-cohort (APC) model based on the intrinsic estimator (IE) algorithm were utilized. Data from the period 1989–2018 were extracted from the International Agency for Research on Cancer (IARC) Database of WHO (1989–2000) and China Health Statistical Yearbook database (2002–2018).

Results

Our study found mortality from cervical cancer to have initially declined, but increase thereafter over the entire observation period in both rural and urban China. The influence of age, period and cohort effect on the mortality rate had statistical significance. The effect of age increased with years, becoming a contributing factor in women aged over 45 years countrywide. Conversely, the cohort effect became a protective factor for women born after 1938 in urban areas, and for women born after 1958 in rural areas. The period effect was relatively less impactful.

Conclusions

The study indicates that organized cervical screening projects facilitated the identification of potential patients, or patients with comorbidities. Correspondingly, mortality was found to increase with incidence, particularly among elderly women, indicating that newly diagnosed patients were at an advanced stage of cervical cancer, or were not receiving appropriate treatment. Therefore, the coverage of cervical cancer screening should be improved, and women’s health awareness promoted. Early diagnosis and treatment is critical to reduce the disease burden and improve outcomes.

Vaccine attitudes among young adults in Asia: a systematic review

Introduction: Young adults may be facing growing threats from vaccine-preventable diseases (VPDs). However, vaccination of young adults may not have drawn adequate attention. In Asia, adensely populated region with ahigh proportion of low-income countries, VPDs impose more of an economic and social burden than in western countries. However, knowledge about attitudes toward vaccines among young Asians is limited. This study aims to fill that gap by describing attitudes toward vaccines and how well they are accepted among young Asian adults through asystematic review of relevant Chinese and English publications.Methods: A three-stage searching strategy was adopted to identify eligible studies published during 2009-2019 according to the selection criteria, resulting in 68 articles being included.Results: The review finds that vaccination coverage among young Asians is generally lower than among their western peers, and there is a lack of relevant study in many Asian countries. Factors influencing young Asians' attitudes toward vaccines are categorized into contextual level, individual and social level, and vaccine-specific level.Conclusion: These suggest that there is a need to strengthen young adults' vaccination programs and to promote vaccine-related information and government.

Multidimensional social and cultural norms influencing HPV vaccine hesitancy in Asia

HPV vaccine hesitancy in Asia is unique compared to Western countries due to multidimensional social-cultural norms that influence beliefs regarding vaccination. Reviews on HPV vaccine hesitancy in Asia lack of in-depth discussion regarding the traditional and social-cultural norms dimensions. This paper puts forward opinions in which culture, normative beliefs, and religion influence HPV vaccine hesitancy in Asian countries. Issues surrounding HPV hesitancy among parents, young adult women, adult women, men and the sexual and gender minority people in Asian countries were highlighted. The shortage of HPV vaccine supply would soon be reduced as some Asian countries are on the way to producing the HPV vaccine which production is currently dominated by Western European countries. The culture of favoring imported Western products among many in Asia and in addition to long-existing fake vaccine crisis pose a challenge for the newly emerging HPV vaccine produced in Asia. Some recommendations, research gaps, and future research needs were discussed.

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.

Analysis of community-based studies related with knowledge, awareness, attitude, and behaviors towards HPV and HPV vaccine published in Turkey: A systematic review

Human papilloma virus (HPV) vaccine is a proven method for preventing HPV-related cancers and genital warts, especially preventing cervical cancer. It is aimed to systematically review and synthesize conclusions in detail from community-based studies published in Turkey between 2009 and 2019, which evaluate the knowledge, awareness, attitude, and behaviors of individuals towards HPV and HPV vaccination. This systematic review is conducted based on the PRISMA reporting method and includes community-based, descriptive cross-sectional and cross-sectional studies published between 2009 and 2019. In this systematic review, 5132 studies from six databases were scanned in total. It was determined that there were 23 studies that met the eligibility criteria for this systematic review. In the reviewed studies, it was determined that the rate of “Hearing of HPV before” was 3.8% at the lowest and 57.0% at the highest, and the rate of “Hearing of HPV vaccine before” was 2.2% at the lowest and 74.7% at the highest. In the reviewed studies, it was reported that although parents’ willingness to have their daughters vaccinated with HPV vaccine varied between 14.4% and 68.0%, their willingness to have their sons vaccinated with HPV vaccine varied between 11.0% and 62.0%. In addition, it was reported that the lowest rate of vaccination with HPV vaccine among participants was 0.3% at the lowest and 6.0% at the highest. Consequently, it is considered that conducting common, systematic, and continuous health education programs aimed at both sexes and including both parents, which will increase the knowledge and awareness on HPV and its vaccine, would provide positive attitudes, and will be effective in protecting against HPV-related cancers.

Chinese mothers' intention to vaccinate daughters against human papillomavirus (HPV), and their vaccine preferences: a study in Fujian Province

Little is known regarding Chinese mothers' intention to vaccinate their daughters against human papillomavirus (HPV) since the HPV vaccine was approved for use in China in 2016. The aim was to explore maternal HPV vaccination acceptance, preference for 2-, 4- or 9-valent HPV vaccine and acceptance of domestically manufactured HPV vaccines. Study participants were mothers of primary school children in Southeastern region of Fujian. An online cross-sectional survey was undertaken between June and August 2019. Among the total of 3,586 completed responses (response rate 28.5%), the intention to vaccinate daughter against HPV was high (83.3%). Higher maternal education and perceived benefit and barriers were associated with greater intention to vaccinate. Among mothers who did not intend to vaccinate their daughters, the three most common reasons were daughter being too young to receive HPV vaccination (40.6%), fear of side effects (31.9%) and vaccine price is too high (16.0%). The largest proportion (41.4%) preferred their daughter to be vaccinated with the 9-valent HPV vaccine (9vHPV). Greater preference for 9vHPVwas strongly associated with higher maternal education level and annual household income. The majority of mothers expressed a preference for imported HPV vaccine (56.3%). Our result indicates that lower intentions to vaccinate daughters against HPV among less educated and lower-income mothers may lead to significant social inequalities in HPV vaccine uptake in the country.

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.

Knowledge, attitudes, and practices of Saudi physicians regarding cervical cancer and the human papilloma virus vaccine

BACKGROUND

Cervical cancer is considered the second most common type of cancer in women worldwide, with a reported 570,000 incident cases documented each year. Infection with certain types of the Human Papillomavirus (HPV) has been found to be associated with more than 99% of cervical cancers. The HPV vaccine can prevent HPV infection and most cases of cervical cancers; however the uptake of this vaccine remains low in Saudi Arabia. Physicians can play a vital role in providing their patients with objective information regarding the HPV vaccine, yet little is known about their knowledge, attitudes, and practices in this area.

MATERIALS AND METHODS

We conducted a cross-sectional study in King Abdul-Aziz Medical City (KAMC), Central Region, Saudi Arabia where data were collected through an online questionnaire to assess the knowledge, attitudes, and practices of physicians.

RESULTS

Most physicians (61%) displayed a good level of knowledge about cervical cancer; 94% were knowledgeable of the causative link between (HPV) infection and cervical cancer. Family medicine physicians had better knowledge regarding cervical cancer, HPV, and HPV vaccination than pediatricians (p=0.023). Physicians with >10 years of practice had better knowledge of cervical cancer than other respondents (p=0.041). 80% of the sample thought it was important for women to receive the HPV vaccine and 82% stated they would allow their daughters to be given the HPV vaccine. Lack of parental knowledge of the vaccine was significantly (p=0.034) associated with a lack of knowledge about HPV, and this was one of the most common barriers preventing recommendation of the HPV vaccine.

CONCLUSION

With the increasing prevalence of HPV infections, better knowledge of HPV infection, HPV-related diseases, and the availability of HPV vaccinations from health professionals will assist with the implementation of effective prevention and treatment programmes.

Urban-Rural Inequities in the Parental Attitudes and Beliefs Towards Human Papillomavirus Infection, Cervical Cancer, and Human Papillomavirus Vaccine in Mysore, India

STUDY OBJECTIVE

The aim of this study was to compare the parental attitudes and beliefs about human papillomavirus (HPV), cervical cancer, and HPV vaccine between urban and rural areas, India.

DESIGN

Cross-sectional.

SETTING

Mysore, India.

PARTICIPANTS

Parents of school-going adolescent girls.

INTERVENTIONS

Parents completed a self-administered questionnaire.

MAIN OUTCOME MEASURES

Attitudes and beliefs about HPV, cervical cancer, and HPV vaccine.

RESULTS

A total of 1609 parents from urban (n = 778) and rural (n = 831) areas participated in this study. Most of the parents had never heard about HPV (73.6%), did not know that their daughters could get an HPV infection (62.7%) or cervical cancer (64.1%) in the future, and believed that HPV vaccine was not effective (67.1%). Parents living in the urban area were more likely to believe that HPV infection (adjusted odds ratio [aOR], 2.69; 95% confidence interval [CI], 1.43-5.06) and cervical cancer (aOR, 2.68; 95% CI, 1.83-3.91) could cause serious health problems than those living in the rural area. The odds of agreeing that HPV vaccination will make girls sexually active was lower among urban than rural parents (aOR, 0.55; 95% CI, 0.33-0.94). There was no significant difference among parents in the urban and rural areas in their beliefs about susceptibility of their daughter to HPV infection or cervical cancer, and beliefs about the safety and ability of HPV vaccine to protect against cervical cancer.

CONCLUSION

Rural parents might be reluctant to recommend behaviors that can help prevent HPV infection and cervical cancer such as HPV vaccination for their daughters.

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.

Knowledge of cervical cancer and HPV vaccine in Bangladeshi women: a population based, cross-sectional study

BACKGROUND

The objective of this study was to assess the level of knowledge of cervical cancer among Bangladeshi women and to assess their willingness to receive the human papillomavirus (HPV) vaccine.

METHODS

A population-based, cross-sectional survey was conducted from July to December 2011 in one urban and one rural area of Bangladesh. A total of 2037 ever-married women, aged 14 to 64 years, were interviewed using a structured questionnaire. Data on socio-demographic characteristics and knowledge of cervical cancer were collected. Willingness to receive the HPV vaccine was assessed. Univariate analyses were completed using quantitative data collected. Multivariable logistic regression models were developed to identify factors associated with having heard of cervical cancer and the HPV vaccine.

RESULTS

The majority of study participants reported to have heard of cervical cancer (urban: 89.7%, rural 93.4%; P = 0.003). The odds of having heard of cervical cancer were significantly higher in urban women aged 35-44 years (aOR: 2.92 (1.34-6.33) and rural women aged 25-34 years (aOR: 2.90 (1.24-6.73) compared to those aged less than 24 years. Very few women reported to have detailed knowledge on risk factors (urban:9.1%, rural: 8.8%) and prevention (urban: 6.4%, rural: 4.4%) of cervical cancer. In our sample, one in five urban women and one in twenty rural women heard about a vaccine that can prevent cervical cancer. Among urban women, secondary education or higher (aOR: 3.48, 95% CI: 1.67-7.25), age of 20 years and above at marriage (aOR: 2.83, 95% CI: 1.61-5.00), and high socioeconomic status (aOR: 2.25, 95% CI: 1.28-3.95) were factors associated with having heard of the HPV vaccine. Willingness to receive the HPV vaccine among study participants either for themselves (urban: 93.9%, rural: 99.4%) or for their daughters (urban: 91.8%, rural: 99.2%) was high.

CONCLUSIONS

Detailed knowledge of cervical cancer among Bangladeshi women was found to be poor. Education on cervical cancer must include information on symptoms, risk factors, and preventive methods. Despite poor knowledge, the study population was willing to receive the HPV vaccine.

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 and Awareness of Cervical Cancer, Human Papillomavirus (HPV), and HPV Vaccine Among HPV-Infected Chinese Women

Background

It is important to understand the knowledge that various groups of a population have about cervical cancer and human papillomavirus (HPV) and their attitudes toward HPV vaccination, as it will ultimately influence their decision-making for or against the acceptability of vaccines and other preventive methods. This study was designed to determine the level of knowledge and awareness about cervical cancer, HPV, and the HPV vaccine among Chinese women in Yunnan province.

Material/Methods

A survey was conducted in Yunnan province by the Laboratory of Molecular Virology in collaboration with the Yunnan First People’s Hospital in Feb 2015. A total of 388 women were recruited and asked to participate in a questionnaire-based interview that collected information related to their awareness and knowledge about: (1) cervical cancer, (2) HPV and HPV vaccine and willingness to have their children receive vaccination, and (3) demographic characteristics.

Results

A total of 388 HPV-positive women were included; 300/388 (73.3%) were Han, and 88/388 (22.7%) were other ethnicities. Overall, 204/388 (52.6%) of the women were aware of cervical cancer, with a significant difference between Han women and women of other ethnic groups (168/388, 56.0% and 36/88, 40.9%; P=0.015). Overall, 26.5% of the women were aware of the role of HPV in cervical cancer; 29.0% of the Han women and 18.2% of women of other ethnic groups were aware of this role of HPV (P=0.05). The knowledge that HPV infection leads to cervical cancer was higher among Han women (29.0%) compared to women of other ethnicities (18.2%). Knowledge about the HPV vaccine was very low in all ethnic groups, but the Han women were more willing to allow their children to be vaccinated before they become sexually active. A similar difference has also been found in women from various regions.

Conclusions

Although level of awareness and knowledge about cervical cancer was moderate, knowledge and awareness of HPV and the HPV vaccine was very low. Targeted communication is very important among populations in which knowledge gaps exist in order to promote dialogue about the vaccine among patients and their healthcare providers.

Ethnic Variations in Perception of Human Papillomavirus and its Vaccination among Young Women in Nepal

BACKGROUND

The Human Papillomavirus (HPV) is strongly associated with cervical and other cancers. In women, cervical cancer is the third most common cancer. HPV infection can be largely prevented through vaccination of (adolescent) girls. At the same time, Nepal is a low-income country experiencing a cultural change in attitudes towards sex and sexual behaviour. However, in the adolescent population knowledge about HPV, factors associated with an increased risk of HPV and the existence of the vaccination is often low.

MATERIALS AND METHODS

This was a cross-sectional study with female students enrolled in health and non-health science courses in Pokhara, Nepal. The questionnaire included demographic details, knowledge and attitude questions related to HPV, associated risk behaviour and its vaccination. Descriptive statistics, including Chi-Square test, were used to identify statistically significant relationships. Ethical approval was granted by the relevant authority in Nepal.

RESULTS

Hindu religion (75.0 %; 95% CI: 70.9, 78.6) and Newari caste (75.5%; CI: 61.1, 86.7) were more aware about HPV, HPV vaccination. Hindus religion (55.6%; 95% CI: 51.2, 60.0) and Dalit caste (61.6%, 95% CI: 53.3, 69.4) more willing to be vaccinated than other religions and other castes, respectively. Not unsurprisingly, students on health-related courses had a greater awareness of HPV, HPV vaccination and were more willing to be vaccinated than students on other courses. Similar patterns of association arose for knowledge related to those sexually active at an early age; HPV risk and multiple sex partners; and fact that condoms cannot fully prevent the transmission of HPV.

CONCLUSION

Knowledge about the link between HPV and (a) early sexual initiation, (b) having multiple sexual partners, and (c) the limited protection of condoms and other birth control measures was poor in our study compared to similar research conducted in other parts of the world. One key implication is the need for education campaigns in Nepal to educate young women and their parents about HPV, its risk factors and the benefits of vaccination. .

Effect of an Educational Intervention on Knowledge of Human Papillomavirus Vaccination among Pre-University Students in Malaysia

BACKGROUND

Cervical cancer is the fourth most common cancer among women worldwide. Studies evaluating the effect of health education on knowledge and perception of cervical cancer have generated conflicting results. Thus, this study aimed to evaluate the effect of educational intervention towards knowledge of HPV vacccination for cervical cancer prevention among pre-university students in Malaysia.

MATERIALS AND METHODS

This was an experimental before and after study performed between October 2014 and March 2015. Five hundred and eighty students were randomly assigned into intervention and control groups. All were required to complete both pre-intervention and post-intervention questionnaires. Those in the intervention group were given an information leaflet to read before answering the post-intervention questionnaire.

RESULTS

Almost half (48.3%) of the students had poor knowledge, with a score less than 5, and only 51 (8.8%) exhibited good knowledge, with a score of 11 and above. After educational intervention, the number of students with poor knowledge was reduced to 177 (29.3%) and the number of students who exhibited good knowledge increased to 148 (25.5%). Students from the intervention group demonstrated significant higher total scores in knowledge regarding 'HPV infection and cervical cancer' (p=0.000) and 'HPV vaccination and cervical cancer prevention' (p=0.000) during post-intervention as compared to the control group.

CONCLUSIONS

Knowledge on HPV infection and vaccination is low among pre-university students. Educational intervention in the form of information leaflets appears effective in creating awareness and improving knowledge.

Parental Refusal of the Human Papillomavirus Vaccine

INTRODUCTION

The purpose of this study was to explore reasons why parents may defer administration of the human papillomavirus (HPV) vaccine to their children. The literature suggests that parents choose to defer administration of this vaccine for several reasons. Data from this pilot study will contribute to our understanding of why parents defer administration of the vaccine.

METHOD

This mixed-methods study took place in a pediatric practice. After a health care visit in which the vaccine was deferred, a survey was provided to the parent in a private room. The survey was confidential and anonymous.

RESULTS

A total of 23 surveys were completed. Demographic data were reported. Data were analyzed for descriptive statistics and themes from open-ended questions. The majority of parents (75%) deferred administration of the HPV vaccine because they believed it was too new or required further research.

DISCUSSION

Nurse practitioners are in an excellent position to dispel myths and clarify information about HPV vaccination. The data are useful in communicating with parents and promoting best practices to facilitate good health in children.

Nationwide Survey of Knowledge and Health Beliefs regarding Human Papillomavirus among HPV-Vaccinated Female Students in Malaysia

The National HPV Immunization Programme, which offers free human papillomavirus (HPV) vaccines to teenaged female students, was launched in Malaysia in 2010. HPV vaccination paired with adequate knowledge about HPV infection provides the best protection against cervical cancer. To identify the level of knowledge and the health beliefs towards HPV and the HPV vaccine among HPV-vaccinated female students in Malaysia. A nationwide cross-sectional survey among 14 years old female students who had received three doses of the HPV vaccine was conducted in 32 randomly selected schools from 13 states and 3 federal territories in Malaysia between February 2013 and April 2013. Among 2482 respondents, knowledge about HPV infection and the HPV vaccine was extremely poor. The mean total knowledge score was only 3.56 (SD ± 1.76), out of a possible score of 10. The majority of respondents were unaware that vaccinating boys with HPV can help protect girls against HPV infection (91.6%), HPV cannot be cured (81.6%) and that HPV is a sexually transmitted infection (70.3%). Most of the respondents had the misconception that only females get HPV (95.1%), and that the HPV vaccine eliminates the need for Pap smear tests (68.3%). Most respondents (91.6%) believed that they would not get an HPV infection. Almost half of the respondents (42.9%) held the misconception that HPV infection could not lead to serious illness. Findings revealed poor knowledge about both HPV and the HPV vaccine, low perceived susceptibility to HPV infection and misinformation about HPV infection among HPV-vaccinated girls. Therefore, it is essential to increase the knowledge and awareness of health risks regarding HPV infection among teenaged girls who have received the HPV vaccine.

Factors Associated with Uptake of Visual Inspection with Acetic Acid (VIA) for Cervical Cancer Screening in Western Kenya

PURPOSE

Cervical cancer screening has been successful in reducing the rates of cervical cancer in developed countries, but this disease remains the leading cause of cancer deaths among women in sub-Saharan Africa. We sought to understand factors associated with limited uptake of screening services in our cervical cancer-screening program in Western Kenya.

PARTICIPANTS AND METHODS

Using items from a previously validated cancer awareness questionnaire repurposed for use in cervical cancer and culturally adapted for use in Kenya, we interviewed 2,505 women aged 18-55 years receiving care in gynecology clinics or seeking other services in 4 health facilities in Western Kenya between April 2014 and September 2014. We used logistic regression modeling to assess factors associated with uptake (or non-uptake), associated odds ratios (ORs) and the 95% confidence intervals (95% CI).

RESULTS

Only two hundred and seventy-three women out of 2505 (11%) accepted VIA cervical cancer screening. Knowledge of just how women are screened for cervical cancer was significantly associated with reduced uptake of cervical cancer screening (OR: 0.53; CI 0.38-0.73) as was fear that screening would reveal a cancer (OR 0.70; CI 0.63-0.77), and reliance on prayer with the onset of illness (OR 0.43; CI 0.26-0.71). Participants who thought that one should get cervical cancer screening even if there were no symptoms were more than twice as likely to accept cervical cancer screening (OR 2.21; 95% CI 1.24-3.93). Older patients, patients living with HIV and women who do not know if bleeding immediately after sex might be a sign of cervical cancer were also more likely to accept screening (OR 1.03, CI 1.02-1.04; OR 1.78, CI 1.01-3.14; OR 2.39, CI 1.31-4.39, respectively).

CONCLUSIONS

In our population, a high percent of women knew that it is appropriate for all women to get cervical cancer screening, but only a small proportion of women actually got screening. There may be an opportunity to design educational materials for this population that will not only encourage participation in cervical cancer screening but also remediate misconceptions. The discussion illustrates how our findings could be used in such an effort.

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.

A community-based intervention in middle schools to improve HPV vaccination and cervical cancer screening in Japan

AIM

Japan has low rates of cervical cancer screening and Human papilloma virus (HPV) vaccination. This research examines the effectiveness of a family medicine resident-led, intervention in increasing knowledge about HPV and cervical cancer in middle school-girls and increasing knowledge and intention to have cervical cancer screening in their mothers.

METHODS

We utilized a pre-test/post-test intervention design in three rural middle schools with 7(th) grade middle school-girls and their mothers. A school-based activity educated girls about HPV and cervical cancer. A home-based activity utilized a homework assignment for girls and their mothers. Pre/post intervention surveys were completed by the girls and their mothers. Major outcomes included changes in knowledge among girls and mothers and barriers to be screened for cervical cancer among mothers.

RESULTS

Sixty-five students and sixty-three mothers completed the study. Two out five mothers were not in compliance with current screening recommendations. Identified barriers included: embarrassment (79%), poor access (56%), fear of having cancer (52%), and cervical cancer screening being an unknown procedure (46%). Forty-four percent of mothers deemed their daughters to be at risk for cervical cancer. Trusted sources of information included: doctors (97%), newspapers/television (89%), government (79%), the Internet (78%), and friends (62%). Student knowledge scores (7-point scale) improved significantly from pre- to post-intervention (4.8 vs. 5.9, p < 0.001). Knowledge scores (14-point scale) among mothers also significantly improved (11.7 vs. 12.0, p = 0.024).

CONCLUSIONS

These data suggest a community-based intervention on a sensitive topic by family medicine residents can be implemented in middle schools, can improve school-girls' knowledge about HPV and cervical cancer, and can reach their mothers. Additional research could examine whether those intending to be screened receive screening and how to reach women who still resist screening.

Human papillomavirus knowledge and awareness among Vietnamese mothers

Human papillomavirus (HPV) is the most common sexually transmitted disease in the US and the primary cause of cervical cancer. Vietnamese American women have the highest incidence rates of cervical cancer but one of the lowest HPV vaccination rates. Parental knowledge is an important predictor of HPV vaccination; however, little is known about HPV knowledge in the Vietnamese American community. We aimed to describe the HPV knowledge of Vietnamese mothers in Houston, Texas and their intention to vaccinate their daughters. We conducted face-to-face interviews with Vietnamese mothers who had daughters aged 9-26 years. We collected data on demographics, acculturation, HPV knowledge, and vaccination intention. Knowledge scores (0-5) were calculated using 5 knowledge questions. We used logistic regression to identify predictors of HPV knowledge. Participants had low levels of acculturation by report of reading (31%) and writing (23%) English well. Less than 50% of participants (n = 47) had heard of HPV, and among these, the mean HPV knowledge score was 4. Although only 1 in 3 had discussed HPV with their medical provider, nearly 86% of participants who had not heard of HPV would vaccinate their daughter if their doctor had recommended it. Good written English skills and belief that the HPV vaccine was not expensive were predictors of HPV awareness. HPV awareness is low among less acculturated Vietnamese mothers in Houston. Future educational efforts about the role of HPV vaccine in preventing cervical cancer should be made in their language when targeting parents of a high risk Vietnamese population.

Knowledge Level of Human Papillomavirus, Cervical Cancer and Vaccination Status among Mothers with Daughters in High School

PURPOSE

The goal of this study was to examine knowledge level of human papillomavirus (HPV), cervical cancer, and vaccination status among Korean mothers' with a daughter in high school.

METHODS

A cross-sectional descriptive study was conducted with a convenience sample of 234 Korean mothers.

RESULTS

The mean score of HPV knowledge level was 4.21 out of 20, and cervical cancer knowledge was 3.88 out of 7. There were low levels of daughters' who received HPV vaccination (3.8%) and high levels of mothers' intention to get their daughters' vaccinated with HPV (85.0%). The major barrier to HPV vaccination was the concern for side effect from the vaccination. The most effective recommendation for HPV vaccination came from health care providers.

CONCLUSION

HPV educational programs targeting mothers of daughters in high school is needed. Future studies need to determine actual HPV vaccination rates and factors related to high uptake using a larger sample from various socioeconomic background.

A cross-sectional study to assess HPV knowledge and HPV vaccine acceptability in Mali

Despite a high prevalence of oncogenic human papilloma virus (HPV) infection and cervical cancer mortality, HPV vaccination is not currently available in Mali. Knowledge of HPV and cervical cancer in Mali, and thereby vaccine readiness, may be limited. Research staff visited homes in a radial pattern from a central location to recruit adolescent females and males aged 12-17 years and men and women aged ≥ 18 years (N = 51) in a peri-urban village of Bamako, Mali. Participants took part in structured interviews assessing knowledge, attitudes, and practices related to HPV, cervical cancer, and HPV vaccination. We found low levels of HPV and cervical cancer knowledge. While only 2.0% of respondents knew that HPV is a sexually transmitted infection (STI), 100% said they would be willing to receive HPV vaccination and would like the HPV vaccine to be available in Mali. Moreover, 74.5% said they would vaccinate their child(ren) against HPV. Men were found to have significantly greater autonomy in the decision to vaccinate themselves than women and adolescents (p = 0.005), a potential barrier to be addressed by immunization campaigns. HPV vaccination would be highly acceptable if the vaccine became widely available in Bamako, Mali. This study demonstrates the need for a significant investment in health education if truly informed consent is to be obtained for HPV vaccination. Potential HPV vaccination campaigns should provide more information about HPV and the vaccine. Barriers to vaccination, including the significantly lower ability of the majority of the target population to autonomously decide to get vaccinated, must also be addressed in future HPV vaccine campaigns.

Female human papillomavirus (HPV) vaccination: global uptake and the impact of attitudes

Human papillomavirus (HPV) is the causative agent in cervical cancer and has been implicated in a range of other malignancies. Preventative vaccines are now internationally available and provide high levels of protection from common viral strains. The introduction of a comprehensive vaccination programme (except 'program' in computers) could prevent over 60% of current cervical cancer cases, but this is dependent on such programmes achieving a high level of coverage. In this review, we summarise the current trends in female HPV vaccination coverage throughout the world, and place it in the context of available research on attitudes towards vaccination amongst the public and health professionals. Where countries have the resources for mass vaccination programmes, uptake has varied. School-based opt-out programmes consistently achieve highest coverage, whilst countries and regions without systematic vaccination schemes have low coverage. In all countries, the success of vaccination programmes is dependent on the support of the public and healthcare professionals. Whilst public acceptance is dependent on multiple factors, it has repeatedly been shown that recommendation by a health professional, particularly clinicians, is key to vaccine uptake. Worryingly, it appears that a proportion of clinicians still have significant reservations about promoting vaccination, particularly for younger age groups. A commitment now, to fully educating both the public and clinicians, has the potential to make a dramatic future impact.

Perceived risk of cervical cancer in Appalachian women

OBJECTIVE

To examine perceptions of cervical cancer risk in elevated-risk Appalachians.

METHODS

Appalachian women (n=571) completed interviews examining self-regulation model factors relevant to perceived risk of cervical cancer.

RESULTS

Women with good/very good knowledge of cervical cancer, greater worry, and history of sexually transmitted infection had higher odds of rating their perceived risk as somewhat/much higher than did other women. Former smokers, compared to never smokers, had lower risk perceptions.

CONCLUSIONS

Self-regulation model factors are important to understanding perceptions of cervical cancer risk in underserved women. The relationship of smoking and worry to perceived risk may be a target for intervention.

Cervical cancer awareness and screening in Botswana

OBJECTIVE

Cervical cancer remains a leading cause of death in many developing countries because limited screening by Papanicolaou (Pap) smear. We sought to better understand women's beliefs about cervical cancer and screening in Botswana, a middle-income African country with high rates of cervical cancer.

METHODS

We interviewed 289 women attending general medicine or human immunodeficiency virus (HIV) clinics, where Pap testing was available, in Gaborone, Botswana, in January 2009.

RESULTS

About three fourths (72%) of the respondents reported having ever had a Pap smear; HIV-positive women were more likely to have had a Pap smear than HIV-negative women (80% vs 64%; odds ratio, 1.97; 95% confidence interval, 1.10-3.55). Screening was also more common among women who were older, had higher incomes, or had heard of cervical cancer. Almost all participants reported a desire to have a Pap smear. Reasons included to determine cervical health (56%), to improve overall health (33%), and to obtain early treatment (34%). About half (54%) of the respondents said they did not know what causes cervical cancer, and almost none attributed the disease to human papillomavirus infection.

CONCLUSIONS

Study findings can inform interventions that seek to increase cervical cancer awareness and uptake of screening as it becomes more widely available.

Safety reporting in developing country vaccine clinical trials-a systematic review

With more vaccines becoming available worldwide, vaccine research is on the rise in developing countries. To gain a better understanding of safety reporting from vaccine clinical research in developing countries, we conducted a systematic review in Medline and Embase (1989-2011) of published randomized clinical trials (RCTs) reporting safety outcomes with ≥50% developing country participation (PROSPERO systematic review registration number: CRD42012002025). Developing country vaccine RCTs were analyzed with respect to the number of participants, age groups studied, inclusion of safety information, number of reported adverse events following immunization (AEFI), type and duration of safety follow-up, use of standardized AEFI case definitions, grading of AEFI severity, and the reporting of levels of diagnostic certainty for AEFI. The systematic search yielded a total number of 50 randomized vaccine clinical trials investigating 12 different vaccines, most commonly rotavirus and malaria vaccines. In these trials, 94,459 AEFI were reported from 446,908 participants receiving 735,920 vaccine doses. All 50 RCTs mentioned safety outcomes with 70% using definitions for at least one AEFI. The most commonly defined AEFI was fever (27), followed by local (16) and systemic reactions (14). Logistic regression analysis revealed a positive correlation between the implementation of a fever case definition and the reporting rate for fever as an AEFI (p=0.027). Overall, 16 different definitions for fever and 7 different definitions for erythema were applied. Predefined AEFI case definitions by the Brighton Collaboration were used in only two out of 50 RCTs. The search was limited to RCTs published in English or German and may be missing studies published locally. The reported systematic review suggests room for improvement with respect to the harmonization of safety reporting from developing country vaccine clinical trials and the implementation of standardized case definitions.
