Abstract
Despite the ongoing global vaccination campaign aimed at preventing human papillomavirus (HPV) related health issues, the uptake of the HPV vaccine remains unacceptably low in developing regions, particularly in sub-Saharan Africa (SSA). Therefore, this systematic review and meta-analysis aimed at determining the pooled prevalence and associated factors of HPV vaccine uptake among adolescent school girls in SSA. Electronic bio-medical databases were explored. Pooled prevalence, publication bias, meta-regression, sub-group, and sensitivity analysis were performed. The estimated pooled prevalence of HPV vaccine uptake was 28.53% [95% CI: (5.25, 51.81)]. Having good knowledge and a positive attitude was significantly associated with HPV vaccine uptake in SSA. Subgroup analysis revealed the highest uptake was 62.52% from Kenya and the lowest was 3.77% in Nigeria. The HPV vaccine uptake is low. It underscores the need for community education, school-based immunization, and education programs that promote the uptake of the vaccine to increase coverage.

Abstract
Introduction Globally, cervical cancer(CC) is the second most commonly diagnosed cancer and the fourth leading cause of cancer-related deaths in women. Human papillomavirus (HPV) infection is the leading cause of CC. Persistent infection with HPV accounts for 90% of all CC cases. The human papillomavirus vaccine has the great potential to prevent HPV-related infections for millions of women and men. The current study aimed to assess knowledge and perceptions towards the HPV vaccine and its determinants among women who have eligible daughters in Debre Berhan City, Ethiopia. Methods A cross-sectional study was conducted from April 2, 2023, to May 15, 2023. A multistage sampling procedure was used to recruit 607 women participants. Descriptive statistics were used to summarize socio-demographic data. Univariable and multivariable binary logistic regression analyses were performed to measure the associations between the dependent and independent variables. A p-value of <0.05 was considered statistically significant. Results More than three-fourths of the participants, 479 individuals (80%) were currently married, and 243(40.1%) had a diploma or higher education level. Of 456(75.12) participants reported, they had information about cervical cancer. For 449(73.9%) of the participants, television was the main evidence. The majority of 352(59.99%) participants knew the HPV vaccine could be offered to a female child aged 9-14 years old. Only 215(35.4%) participants think the HPV vaccine was safe and effective. Women who had a degree and above educational level were about 9 times more likely to have good knowledge about the HPV vaccine than study participants who did not read and write (AOR=9.21; 95% CI=2.82-12.16; p=0.004). Women who did not have information about the HPV vaccine before this study were about 80% less likely to have a positive perception of the HPV vaccine than participants who had earlier information about the HPV vaccine (AOR=0.8; 95%CI=0.63-0.49; P=003). Conclusion Women had poor knowledge and perceptions about the HPV vaccine. Maternal marital status, age, and having information about the HPV vaccine were the only predictors of women's knowledge of the HPV vaccine.

Abstract
Purpose: Studies reported that early diagnosis, treatment, and prevention of cervical cancer are influenced by knowledge, beliefs, and attitude toward screening. This descriptive-comparative study aimed to assess human papilloma virus (HPV) knowledge, attitudes, and beliefs in university students and the affecting factors and to compare between Turkish and Ghanaian students. Methods: The sample consists of 933 university students studying in 4 different faculties in 2 universities from Turkey and Ghana. The data were collected between November 2019 and February 2020. The study's data were analyzed using Analysis of Variance, Pearson Correlation test, t-test, and Mann-Whitney U test. Results: The findings of the study showed that none of the students in both countries had HPV vaccination. It was found that students have low level of knowledge about HPV infection and vaccine (3.28 ± 2.14) and positive attitudes (16.57 ± 3.28) and beliefs (36.74 ± 6.55) toward vaccine. The attitude score of the Ghanaian students (17.54 ± 3.23) was found to be significantly higher than the Turkish students (15.74 ± 3.09). The knowledge score of the Ghanaian students who had sexual intercourse was found to be significantly higher than others. The findings of the study revealed that the students of both countries had low level of knowledge about HPV infection and vaccine and positive attitudes and beliefs toward the vaccine. Conclusions: It is recommended to increase effective interventions to increase the knowledge level of university students about HPV infection and vaccine. In addition, the vaccine should be included in the immunization program in both countries.

Abstract
BACKGROUND Human papillomavirus (HPV) is linked to cervical cancer, which is prevalent in Saudi Arabia. While HPV vaccines are effective, their coverage remains low in low- and middle-income countries. Public awareness of HPV vaccination is also limited. The study examines public awareness of cervical cancer, HPV, the HPV vaccine, and factors that hinder vaccine uptake. OBJECTIVES To assess the levels of knowledge, attitudes, and perceptions towards HPV vaccination among women aged 16 years and above in Makkah, Saudi Arabia. METHODS An analytical cross-sectional study was conducted using an interview questionnaire. A stratified sampling technique was used to select a representative sample of 534 female patients aged 16 years and older who visited primary healthcare centers in Makkah. The interview questionnaire included questions related to sociodemographic characteristics, knowledge about HPV vaccination, attitudes and perceptions toward HPV vaccination, and sources of information about HPV infection and vaccines. The data were analyzed using descriptive statistics and chi-square tests. RESULTS The majority of participants were aged between 21 and 40 years (76.4%), Saudi (90.3%), and had a higher education level (73.4%). Only a small proportion (1.9%-39%) of participants correctly answered most of the questions related to HPV vaccination, while a few questions were answered correctly by a larger proportion (41.6%-59.6%), highlighting the need for educational programs to increase awareness about the HPV vaccine. The internet and social media were the most prevalent sources of information about HPV infection and vaccines (48.4%). A majority of participants expressed willingness to receive the HPV vaccine if offered by the healthcare sector at no cost (65.5%). Concerns included fear of injection (27.7%), cost (23.2%), and potential refusal from family or community (9.7%). A significant proportion believed that there is a need for educational sessions to increase awareness about the HPV vaccine in their community (82.8%) and that increased knowledge about HPV vaccines would lead to greater acceptability (83.9%). Age, nationality, marital status, number of children, educational status, occupation, and average monthly income were significantly associated with knowledge about HPV vaccination (p < 0.05). Age and educational status were significantly associated with attitudes towards HPV vaccination (p < 0.05). CONCLUSION The lack of knowledge about HPV vaccination among adult women in Makkah, Saudi Arabia, is concerning, as it may result in low vaccine uptake rates and an increased incidence of HPV-related diseases. Therefore, targeted educational programs and awareness campaigns are crucial to enhance knowledge and promote the uptake of the HPV vaccine. These programs should be designed to provide accurate information about the prevalence of HPV, its associated risks, and the benefits of vaccination.

Abstract
We report on a case of multiple evanescent white dot syndrome (MEWDS) following the simultaneous administration of the human papillomavirus and meningococcal (conjugate) vaccines and two recurrences of MEWDS following the administration of the second dose of the human papillomavirus (HPV) vaccine and the COVID-19 vaccine and COVID-19 viral infection. A 17-year-old Hispanic female presented with a one-week history of photopsia and blurred vision in her left eye following the simultaneous administration of the human papillomavirus and meningococcal (conjugate) vaccines. Upon a comprehensive examination, her best-corrected visual acuity was 20/20 in the right eye and 20/100 in the left eye. A left fundus examination revealed multiple white dots in the macula and nasal periphery, consistent with a diagnosis of MEWDS. Ancillary testing, including fundus autofluorescence, fluorescein angiography, indocyanine green angiography, and optical coherence tomography, supported the diagnosis. One month following her initial diagnosis, the patient's symptoms had resolved without any therapy, and a fundus examination revealed multiple relatively ill-defined brown-colored subretinal lesions in the nasal midperiphery, corresponding to the location of the previous MEWDS lesions. Subsequently, she received the second dose of the HPV vaccine and then developed a mild COVID-19 infection. Four months after the initial presentation, she received the first dose of the BNT162b2 COVID-19 vaccine, followed by the second dose a month later. Eight months following her initial presentation, she presented with photopsia in the right eye. Her visual acuity remained 20/20 in the right eye and improved to 20/20 in the left eye, and white dots were identified nasal to the disk and surrounding the peripapillary region; the contralateral MEWDS diagnosis was confirmed by the previously mentioned ancillary tests. At her one-month follow-up, she presented new onset photopsia of the right eye. Her visual acuity remained 20/20 in both eyes, and a fundus examination revealed white lesions suggestive of active MEWDS temporal to the macula and brown-colored spots nasal to the disk, suggestive of recovering MEWDS, nasally. The aforementioned testing confirmed the coexistence of new and resolving lesions; nonetheless, the patient's symptoms resolved without any therapy, and she received the third dose of the BNT162b2 COVID-19 vaccine 11 months after her initial presentation. Our case suggests that vaccines may serve as immunological triggers of MEWDS. Recurrent MEWDS may occur when an individual is exposed to a powerful immune challenge, such as receiving a wide array of vaccinations in a short period of time. We believe this case constitutes a previously undescribed finding of multiple relatively ill-defined brown-colored subretinal lesions present in late MEWDS.

Abstract
Health literacy is associated with the utilization of preventive health services. We examined the association between health literacy (HL) levels and receipt of at least one dose of the human papilloma virus (HPV) vaccination. We analyzed the data from the 2016 Behavioral Risk Factor Surveillance System (BRFSS) among adults aged 18 to 32. The primary outcome variable was the 'yes/no' response to the question that assessed whether the participant received at least the first dose of HPV vaccination. The primary independent variable was a summative HL score (range 3 through 12) we created for each respondent by adding the scores for all three HL questions. We performed bivariate and multivariable (logistic regression) analyses to examine the relationship between study variables. The analytical sample of 6,731 adults aged 18 to 32 met the eligibility criteria. Regression analyses showed that the odds of having received at least one dose of HPV vaccination increased by 13% for every unit increase in health literacy score (Odds ratio: 1.13, 95% CI:1.06-1.21, p < .0001). Age, gender, marital status, race/ethnicity, insurance status, and having regular access to a personal doctor were predictors of HPV vaccination status. This study showed that higher levels of HL may contribute to the uptake of at least one dose of the HPV vaccine. Health care and public health organizations, health care professionals, and policymakers should emphasize improving the health literacy levels of the patients and the public to increase the uptake of the HPV vaccine.

Abstract
For nearly a decade, case reports and series have emerged regarding dysautonomias-particularly postural orthostatic tachycardia syndrome (POTS)-presenting soon after vaccination against human papilloma virus (HPV). We too have observed a number of such cases (all following vaccination with the Gardasil product), and have found several to have detectable mast cell activation syndrome (MCAS) as well as histories suggesting that MCAS was likely present long before vaccination. We detail 11 such cases here, posing a hypothesis that HPV vaccination (at least with the Gardasil product) may have triggered or exacerbated MCAS in teenagers previously not recognized to have it. Only recently recognized, MCAS is being increasingly appreciated as a prevalent and chronic multisystem disorder, often emerging early in life and presenting with inflammatory ± allergic phenomena following from known mast cell (MC) mediator effects. There is rising recognition, too, of associations of MCAS with central and peripheral neuropathic disorders, including autonomic disorders such as POTS. Given the recognized potential for many antigens to trigger a major and permanent escalation of baseline MC misbehavior in a given MCAS patient, we hypothesize that in our patients described herein, vaccination with Gardasil may have caused pre-existing (but not yet clinically recognized) MCAS to worsen to a clinically significantly degree, with the emergence of POTS and other issues. The recognition and management of MCAS prior to vaccinations in general may be a strategy worth investigating for reducing adverse events following HPV vaccinations and perhaps even other types of vaccinations.

Abstract
The HPV vaccine debuted more than ten years ago in the United States and many strategies have been evaluated to increase HPV vaccination rates, which include not only improving current vaccination behaviors but also sustaining these behaviors. Researchers and practitioners from a variety of backgrounds have engaged in this work, which has included efforts directed at public health and government policies, health education and health promotion programs, and clinical and patient-provider approaches, as well as work aimed to respond to and combat anti-HPV vaccination movements in society. Using a previously developed conceptual model to organize and summarize each of these areas, this paper also highlights the need for future HPV vaccine promotion work to adopt a multi-level and, when possible, integrated approach in order to maximize impact on vaccination rates.

Abstract
We herein report a 15-year-old girl who developed rapid progressive muscle weakness soon after the third injection of a bivalent human papilloma virus (HPV) vaccine. Although immunotherapies were performed for possible vaccine-related disorders, she died of respiratory failure 14 months after the onset of the disease. A genetic analysis identified a heterozygous p.P525L mutation of the fused in sarcoma (FUS) gene, and a histopathological analysis was also consistent with FUS-associated amyotrophic lateral sclerosis (ALS) without any evidence of neuroinflammation. We concluded the diagnosis to be FUS-ALS, although we cannot completely rule out the possibility that the vaccination worked as a trigger.

Abstract
OBJECTIVE The current research focuses on sexual risk behaviour among young adult Canadians who have not been vaccinated against HPV. METHODS Six hundred and forty-six Canadian university undergraduates completed a self-administered survey assessing HPV vaccination status and sexual risk behaviour. RESULTS Five hundred and thirty-seven participants (154 men and 383 women aged 17-23) who met eligibility criteria were analyzed. 48.5% (n = 185) of female and 89.6% (n = 138) of male participants had not been vaccinated against HPV. In the unvaccinated cohort, 51.4% (n = 95) of women were coitally experienced, 49.2% (n = 91) reported experience with oral sex, and 6.5% (n = 12) reported experience with receptive anal intercourse. 55.1% (n = 76) of men were coitally experienced, 22.5% (n = 31) of men reported receptive oral sex, and 2.9% (n = 4) of men reported receptive anal intercourse. Using validated sexual risk behaviour cut-offs, we determined that in the female unvaccinated population, the proportion at significantly increased risk for genital warts, cervical, anal, and oropharyngeal cancer was 11.0%, 30.0%, 6.5%, and 49.2% respectively. In the male unvaccinated population, the proportion at significantly elevated risk for genital warts and anal cancer was 27.2% and 2.9% respectively. CONCLUSION Unvaccinated young Canadian women and men commonly engaged in sexual risk behaviours for HPV infection, engaged in sexual risk behaviours at a similar level as their vaccinated counterparts, and a substantial number were at elevated risk of HPV related morbidities at a young age. Findings contribute to an evidence-based case for redoubling efforts to encourage HPV vaccination among unvaccinated young Canadians who are at risk of HPV infection.

Abstract
This commentary explores the distribution of human papilloma virus (HPV) and HPV-related diseases, and factors affecting attitudes towards HPV, HPV-related diseases, and HPV vaccination in the Latin American Andean region. Lack of knowledge of HPV, known negative attitudes or incorrect assumptions about HPV, HPV-related diseases, and HPV vaccination provide a basis upon which to develop targeted HPV awareness and preventive health media campaigns. For maximal effect, media campaigns should use the internet, radio, and television to address health care providers, parents, and students. Additional programming can be developed for clinics to use in-house with their clients. Ministries of Education, Finance, and Health all have roles to play to increase national HPV, HPV-related diseases, and HPV vaccination awareness.

Abstract
AIM To determine the impact of human papilloma virus (HPV) vaccination on knowledge, perception of sexual risk and need for continued safe sexual behavior among Indonesian girls. METHODS A comparative cross-sectional study was carried on in Denpasar, the capital city of Bali, Indonesia, during September 2015-February 2016. A total of 828 adolescent girls (12-16 years) were recruited to assess their knowledge on HPV/HPV vaccine, perception of sexual risks and need for continued safe sexual behavior. RESULTS A total of 419 girls (50.7%) had received HPV vaccination prior to the study, 76.4% of whom (320/419) had sufficient knowledge about HPV. HPV vaccination was a strong and independent predictor of higher HPV/HPV vaccine knowledge (adjusted OR [AOR], 9.358; 95%CI: 6.816-12.849, P < 0.001). HPV vaccination (AOR, 0.107; 95%CI: 0.074-0.155, P < 0.001) and higher knowledge level (AOR, 0.667; 95%CI: 0.464-0.958, P = 0.028) were associated with lower perceived HPV risk. Despite the low risk perception, most of the vaccinated girls (408/419, 97.4%) continued to perceive higher need for safe sexual behaviors. On multivariate analysis, higher knowledge was the independent predictor for higher perceived need for safe sexual behaviors (AOR, 4.260; 95%CI: 2.016-9.001, P < 0.001). CONCLUSION The HPV vaccination was associated with higher knowledge and appropriately lower perception of HPV risk. Despite the vaccination, most of the adolescents continued to perceive a need for safer sexual behavior. All adolescent girls should receive HPV vaccination in order to reduce cervical cancer burden in the future.

Abstract
AIM The aim of our study was to evaluate the level of knowledge of the adolescent girls who presented to our clinic about human papilloma virus (HPV) infection and HPV vaccine. MATERIAL AND METHODS Five hundred and one adolescent girls aged between 13 and 18 years who presented to the gynecology outpatient clinic between March 2012 and March 2013 were asked to answer the questions of the questionnaire about HPV and HPV vaccine. The "Participant Information Form" and "HPV Information Assessment Form" were used by examination of the related literature by the investigators. The data obtained were entered into the computer using the SPSS 16.5 program and evaluated. Descriptive statistics were shown with mean, standard deviation, number and percentage values. RESULTS The mean age of 501 subjects who were included into the study was 15.92 years. 390 subjects (77.8%) who were included in the study had no information about HPV. 111 subjects (22.2%) stated that they heard of HPV before or had information about HPV. The mean age of the subjects who had information about human papilloma virus was found to be 16.52 years. The mean age of 390 subjects (77.8%) who had no information about human papilloma virus was 15.75 years. It was found that only one of the subjects (0.9%) was vaccinated with HPV vaccine. When the subjects who did not wish to be vaccinated were asked for the reason, 40.9% stated that the reason was inadequate information, 26.4% stated that the reason was high cost, 16.4% stated that the reason was the fact that they did not consider themselves at risk and 16.4% stated that the reason was the fact that they were afraid of side effects. CONCLUSIONS In our study, it was found that the adolescent girls who constituted our study group had insufficient information about HPV and HPV vaccine. Verbal, written and visual communication tools and internet should be used intensively and efficiently for the objective of introducing HPV vaccine and teaching the precautions related with prevention of cervix cancer in terms of public health. Primarily pediatrician and gynecologists and family physicians who give service for the adolescence age group should be supported to develop appropriate attitudes and behaviors related with HPV vaccine and infection.

Abstract
Two vaccines that protect against infection by some of the oncogenic human papillomavirus (HPV) subtypes have recently been licensed for use in population-based vaccination strategies in many countries. However, these products are being promoted as ‘cervical cancer vaccines’ based on inadequate data. Specifically, there remain several concerns about the duration of immunogenicity, length of follow-up of trial subjects, endpoints chosen in vaccine trials, applicability of trial results to real populations, the safety of these products, and their cost-effectiveness as public health interventions. Furthermore, it is unlikely that vaccination will obviate the need for setting up robust and cost-effective screening programs in countries like India. This article will discuss various aspects of HPV vaccination from a public health perspective, especially from the point of view of its relevance to India and other South Asian countries.

Abstract
OBJECTIVE We conducted a descriptive study of the correlates of refusal and acceptance of human papillomavirus (HPV) vaccination by rural parents of preadolescent and adolescent children. We hypothesized that the correlates of parents who allow their children aged 9 to 13 years to get the HPV vaccine and those of parents who do not allow vaccination would differ significantly. METHODS This cross-sectional study was implemented during the school years 2009-2011 in the elementary and middle schools of three rural counties in Georgia. Parents were recruited at school functions to complete an anonymous validated survey. RESULTS Parents who chose to vaccinate their children or intended to vaccinate were twice as likely to be from a race other than African American and 2.7 times more likely to have a religion other than Baptist. Using stepwise logistic regression and after adjustment for race and religion, we found that parents who had vaccinated or intended to vaccinate had significantly higher scores on perceived barriers (1.02 times more likely to vaccinate) and lower scores on perceived benefits (1.01 times more likely to vaccinate) (model p < .001). CONCLUSIONS The results suggest that healthcare providers in rural areas can increase HPV vaccine uptake and reduce HPV-related cancers by using a multifaceted approach to educating their patients within the context of the patients' cultural values, geographic location, and economic situation. Such an approach could dispel misinformation and increase vaccine uptake.

Abstract
Genital human papillomavirus (HPV) infection is the most common sexually transmitted infection with an estimated worldwide prevalence of 9-13% and approximately 6 million people being infected each year. Mostly acquired during adolescence or young adulthood, HPV presents clinically as anogenital warts and may progress to precancerous lesions and cancers of the cervix, vagina, vulva, penis and anus, and oropharynx. HPV infection is considered to contribute to almost 100% cervical cancers and at least 80% of anal and 40-60% of vulvar, vaginal, and penile cancers. At present, two prophylactic HPV vaccines are commercially available and both are prepared from purified L1 structural proteins. These proteins self-assemble to form virus-like particles that induce a protective immunity. Gardasil(®) is a quadrivalent vaccine against HPV types 6, 11, 16, and 18 and is recommended for use in females 9-26 years of age, for the prevention of cervical, vulvar, and vaginal cancers and intraepithelial neoplasia and condyloma acuminata and recently for vaccination in boys and men 9-26 years of age for the prevention of genital warts. Cervarix™ is a bivalent vaccine approved for the prevention of cervical cancer and precancerous lesions caused by HPV 16 and 18, in females 10-25 years. HPV vaccines are safe and efficacious against type-specific HPV-induced anogenital warts, precancerous lesions, and cervical cancer. The vaccines are most effective when given before the onset of sexual activity and provide long-term protection. Effective vaccination coverage in young adolescent females will substantially reduce the incidence of these anogenital malignancy-related morbidity and mortality. There is need to generate India-specific data on HPV epidemiology and HPV vaccination efficacy as well as continue worldwide surveillance and development of newer vaccines.
