Safety Of Human Papillomavirus Vaccine Research Articles

Human papillomavirus (HPV) vaccination in Japan.

To review the status of human papillomavirus (HPV) vaccination in Japan from inception to the present, focusing on past and current challenges. Published articles and website content related to HPV vaccination were reviewed. The Ministry of Health, Labor and Welfare suspended proactive recommendations for HPV vaccination in June 2013 following repeated media reports of girls experiencing adverse events, including chronic pain and walking disturbances, after receiving the HPV vaccine. Despite later recognition of these symptoms as a functional somatic syndrome, HPV vaccine coverage of target girls aged 12 to 16 years in the National Immunization Program (NIP) rapidly decreased to near zero. This suspension of the proactive HPV vaccination recommendation ceased in fiscal year (f-year) 2022, initiating a 3-year catch-up free HPV vaccination period from April 2022 to March 2025 for women born from f-years 1997 to 2005. These drastic changes were driven by established evidence of the effectiveness and safety of HPV vaccines reported from both Japan and other countries, and a nine-valent HPV vaccine has been included in the NIP since f-year 2023. However, the estimated HPV vaccination rate in the NIP remains low at ≤30%. To regain high coverage of HPV vaccination in Japan, it is essential that government, industry, and academic society work together to raise awareness and educate Japanese people about cervical cancer prevention and HPV-related diseases.

Intralesional Quadrivalent Human Papilloma Virus Vaccine Versus Candida Antigen in the Treatment of Multiple Recalcitrant Non-Genital Warts.

Warts are the most prevalent clinical manifestation of Human Papilloma Virus (HPV) infections, which vary in morphological pattern depending on the site of the body affected. To evaluate the safety and efficacy of intralesional quadrivalent HPV vaccine versus candida antigen in treatment of multiple recalcitrant non-genital warts. A randomized-control clinical trial included 60 cases with multiple recalcitrant warts who were randomly distributed into three groups; Group I included 20 patients who received intralesional candida antigen at a dose of 0.3 mL of 1/1000 solution, Group II included 20 patients who received intralesional quadrivalent HPV vaccine at a dose of 0.3ml and Group III included 20 patients who received intralesional injection 0.3 ml of normal saline 0.9% as a control group). Each agent was injected at the base of the largest wart every three weeks until it was completely cleared, or for a total of four sessions. the highest response rate was detected in the quadrivalent HPV vaccine group (75% complete response) followed by the candida vaccine group (40% complete response and 15% partial response). Also, regarding the distant response rate, the highest response rate was detected in the quadrivalent HPV vaccine group (72.7% complete response and 27.3% partial response) followed by the candida vaccine group (33.3% complete response and 50% partial response). Intralesional immunotherapy appears to be effective and safe in treating multiple recalcitrant non-genital warts, with intralesional quadrivalent HPV vaccine outperforming intralesional candida antigen.

Adverse events from HPV vaccination in Taiwan

The safety of human papillomavirus (HPV) vaccines has been evaluated continuously in pre-licensure clinical trials, post-marketing surveillance systems, and observational studies. Most studies have found no significant association between serious adverse events and HPV vaccination. However, these studies have focused on Western populations; similar studies focusing on Asian populations are insufficient. Our retrospective cohort study used the HPV-vaccination records of junior high-school adolescent girls aged 12–15 years between 2013 and 2018 in Taiwan’s National Immunization Information System and linked them to a registry for beneficiaries in Taiwan’s National Health Insurance Database (NHID) to establish the vaccinated group. We selected 19 serious diseases as serious adverse events. We compared the incidence rates of these serious adverse events between the vaccinated group and girls in the same age group population, and we calculated the standardized incidence ratio (SIR) to evaluate the risk of serious adverse events after HPV vaccination. Because of the onset of different types of diseases, we set three periods after the subjects received HPV vaccination: within 3 months, within 1 year, and during the study period (2013–2018). The results showed the incidence rates and the SIRs of 19 selected adverse events. Among the 19 selected serious adverse events, the disease with the highest incidence rate during the study period was fibromyalgia (73.23 cases per million population), and the disease with the lowest incidence rate during the study period was Crohn’s disease (0.15 cases per million population). The results showed no statistically significant increases in the risk of 19 selected serious adverse events and indicated no association between HPV vaccination and serious adverse events. Given the benefits and safety of HPV vaccination, our research can reduce concerns about vaccine side effects, inform health policies and improve public and clinician’s acceptance of HPV vaccine policy.

Knowledge and perceptions of French community pharmacists and pharmacy students about the papillomavirus vaccine

IntroductionIn a French context of low vaccination coverage for human papillomavirus (HPV) disease, we conducted a study on pharmacy students and community pharmacists to assess their self-reported knowledge about HPV infection and vaccination and their perceptions of vaccination. Material and methodsA prospective volunteered-based study was conducted in the French Franche-Comté region based on a questionnaire targeting pharmacy students (from the 2nd to 6th years) and community pharmacists. ResultsAll in all, 220 students and 55 pharmacists completed a questionnaire. Fewer than a third knew which HPV genotypes are considered to be high-risk (p-value = 0.11) and were aware of the diversified nature of HPV-induced cancers (p-value = 0.02). Their overall level of general knowledge about vaccination was estimated to be good by 62% of students and 85% of pharmacists (p-value = 10−3). More than 75% of students and pharmacists considered that HPV vaccination has a positive benefit-risk balance (p-value = 0.44) but that its low coverage is due to non-confirmed adverse events that were suggested in the past (p-value = 0.60). Pharmacists had a better perception of the safety of HPV vaccination (84% versus 64%, p-value = 6·10−3). More than 50% of students and pharmacists agreed with mandatory HPV vaccination for girls and boys (11–14 years). ConclusionThis study allowed us to assess the knowledge of students and community pharmacists and their more or less favorable perceptions of HPV vaccination. It helped us to suggest their needs in terms of practical training. Future changes should include pharmacists in the implementation of public health policies and to improve vaccination coverage.

A feasibility assessment of real-world data capabilities for monitoring vaccine safety and effectiveness in China: Human papillomavirus vaccination in the Yinzhou district as a use case.

Real-world data (RWD) are increasingly used to generate real-world evidence (RWE) of vaccine safety and effectiveness for regulatory purposes. Assessing feasibility of using RWD sources prior to implementing observational studies is recommended. As a use case, we described the process and findings of a feasibility assessment to identify reliable and relevant data sources for monitoring the safety and effectiveness of the AS04-HPV-16/18 human papillomavirus (HPV) vaccine in China. Iterative multi-step process: (1) targeted literature review and data source mapping; (2) expert opinion from national RWD experts; (3) survey to evaluate the identified data source operational infrastructure; and (4) continuous appraisal of published studies using the identified data source. The Yinzhou Regional Health Information Platform (YRHIP) was identified as a data source of main interest, based on its large population coverage, high cervical cancer screening rates, and availability of adult electronic immunization records. Field meetings with national RWD experts confirmed its suitability for post-authorization vaccine studies. Survey results showed that exposure data and relevant safety and effectiveness endpoints were recorded and linkable at the individual level across the platform. Iterative appraisal of emerging evidence from the literature corroborated these findings. This feasibility assessment indicates that the YRHIP has the capacity to capture demographic, exposure, outcome and other data required to generate RWE on HPV vaccine safety and effectiveness in China. Studies using the YRHIP to monitor the AS04-HPV-16/18 vaccine in routine use building on this feasibility assessment are ongoing.

Epidemiology of Upper Limb Complex Regional Pain Syndrome in a Retrospective Cohort of Persons Aged 9-30 Years, 2002-2017.

Introduction This paper describes the epidemiology and clinical presentation of complex regional pain syndrome (CRPS) in a large, integrated health care delivery system; and CRPS incidence rates (IRs) over a time period spanning human papillomavirus (HPV) vaccine licensure and published case reports of CRPS following HPV vaccination. Methods The authors examined CRPS diagnoses in patients aged 9-30 years between January 2002 and December 2017 using electronic medical records, excluding patients with lower limb diagnoses only. Medical record abstraction and adjudication were conducted to verify diagnoses and describe clinical characteristics. CRPS IRs were calculated for 3 periods: Period 1 (2002-2006: before HPV vaccine licensure), Period 2 (2007-2012: after licensure but before published case reports), and Period 3 (2013-2017: after published case reports). Results A total of 231 individuals received an upper limb or unspecified CRPS diagnosis code during the study period; 113 cases were verified through abstraction and adjudication. Most verified cases (73%) were associated with a clear precipitating event (eg, non-vaccine-related injury, surgical procedure). The authors identified only 1 case in which a practitioner attributed CRPS onset to HPV vaccination. Twenty-five incident cases occurred in Period 1 (IR = 4.35/100,000 person-years (PY), 95% confidence interval (CI) = 2.94-6.44), 42 in Period 2 (IR = 5.94/100,000 PY, 95% CI = 4.39-8.04), and 29 in Period 3 (IR = 4.53/100,000 PY, 95% CI = 3.15-6.52); differences between periods were not statistically significant. Conclusion These data provide a comprehensive assessment of the epidemiology and characteristics of CRPS in children and young adults and provide further reassurance about the safety of HPV vaccination.

Application of the theoretical domains framework to identify factors influencing catch-up HPV vaccinations among male college students in the United States: A review of evidence and recommendations.

Genital human papillomavirus (HPV) infection is the most prevalent sexually transmitted infection among young adults ages 15-25years in the United States (US). Although HPV vaccines are recommended for individuals ages through 26years, vaccine completion rates remain substantially low. Accordingly, our study utilized a comprehensive - Theoretical Domains Framework (TDF) of behavior change to systematically identify facilitators and barriers to catch-up HPV vaccinations. Five databases - Medline, Embase, CINAHL, ERIC, and PsycINFO were searched from January 2009 to July 2019 for empirical studies using quantitative and qualitative methods to assess HPV vaccine uptake among males ages 18-26years within US college and university settings. The TDF analytic process included a content analysis using the mixed deductive-inductive approach to extract, analyze and categorize data into TDF domains/themes and sub-themes. Overall, 17 studies were selected for data extraction. We identified eleven key TDF domains that influenced HPV vaccination behavior among college male students: 'knowledge' (82% of included studies), 'environmental context and resources' (53%), 'beliefs about consequences' (53%), 'unrealistic optimism' (50%) and 'pessimism' (6%), 'emotion' (50%), 'social influences' (50%), 'beliefs about capabilities' (41%), 'intention' (24%), 'reinforcement' (18%), 'social professional role and identity'(12%), and 'behavioral regulation' (12%). Barriers influencing HPV vaccine uptake included lack of knowledge and awareness regarding HPV infections, HPV vaccine safety, effectiveness, side effects, and costs; absence of health providers' recommendations; lack of healthcare and health insurance; low levels of perceived susceptibility and severity for HPV infections; HPV vaccine misinformation; as well as social stigma and peer influences regarding HPV vaccinations. Enablers for HPV vaccine uptake included high levels of perceived benefits for HPV vaccines. Our study theoretically identified factors influencing HPV vaccinations. This could inform the efficient planning, support, and implementation of interventions that facilitate catch-up HPV vaccination practices among high-risk males within college/university settings.

Can human papillomavirus vaccination during pregnancy result in miscarriage and stillbirth? A meta-analysis and systematic review.

Contradictory results regarding the safety of human papillomavirus (HPV) vaccination during pregnancy have been obtained, which has cast doubt on the use of this method. This review and meta-analysis were conducted to evaluate the safety of HPV vaccination during pregnancy. Complying with the inclusion and exclusion criteria, we searched Web of Science, Scopus, Medline, EMBASE, PubMed and Google Scholar databases for articles published in the past decade using the following keywords: 'papilloma human virus', 'HPV vaccine', 'pregnancy' and 'safety and prevention'. The minimum report quality of the articles was 16 based on the STROBE checklist. Seven articles were included in the study, three of which were included in the meta-analysis, and the rest were reviewed systematically. The results of the meta-analysis showed that vaccination against HPV during pregnancy or around this period does not increase the risk of miscarriage (RR=2.01; 95% CI: 0.66-6.13) and stillbirth (RR=2.02: 95% CI: 0.65-6.27). No significant difference between miscarriage and stillbirth was observed in women vaccinated against HPV versus those not vaccinated. The study of 1380424 individuals showed that HPV vaccination during pregnancy is better postponed until after this period. However, no significant evidence was found to indicate that vaccination was dangerous and unsafe during pregnancy. Further studies are needed to draw a more definitive conclusion.

Immunogenicity, efficacy,and safety of human papillomavirus vaccine: Data fromChina.

The incidence rate and mortality rate of cervical cancer have steadily increased in young women in China. Therefore, it is critical to improve HPV vaccination rates, particularly for the younger population. There are currently five types of prophylactic vaccines in China: bivalent HPV vaccine (AS04-HPV-16/18), quadrivalent HPV vaccine, 9-valent HPVvaccine, homemade Escherichia coli-produced HPV bivalent vaccine, and Pichia pastoris produced HPV bivalent vaccine. All these five HPV vaccines have completed relevant clinical trials in China, and have been proven to be generally well-tolerated and immunogenic, efficacious against persistent HPV-related infections and genital precancerous lesions (data for 9-valent HPV vaccine is absent), and have demonstrated acceptable safety profiles, as previously shown in global studies. Given that the HPV vaccination rate in China is still very low, additional HPV vaccine coverage is needed to reduce the incidence and mortality rates of cervical cancer.

Assessment of Acceptability and Determinants of Uptake and Schedule Completion of Human Papillomavirus (HPV) Vaccine by 25 to 45 Years Old Women in Slovenia.

HPV immunization programs are mainly focused on girls and boys, but adult women and men could also benefit from vaccination. A multinational CoheaHr-WP4 study investigated the acceptability of HPV vaccination among 25-45 years old women. A total of 607 women from Slovenia participated in the study, and 49.6% (301/607) agreed with HPV vaccination, with a significant difference (p < 0.0001) between the two centers. Non-vaccinated women had a higher education (p = 0.0068) and were more frequently in a committed relationship or married (p = 0.01). The most trusted source of medical and vaccination information was healthcare providers (55.2%). The main reasons for vaccine acceptance were protection against HPV-related disease (93.4%), severity of preventable diseases (82.7%), HPV vaccine safety (66.8%), free HPV vaccine availability (62.8%), and the existence of vaccination recommendations (55.5%). The main reasons for refusing vaccination were the need for additional vaccine-related information (31.4%) and vaccine safety concerns (29.4%). To increase vaccine coverage, information about the benefits and safety of HPV vaccination must be widely disseminated to all health professionals and the general public. We are convinced that the knowledge obtained in this study can be reliably applied to other countries in the region that lack such information and have a very high cervical cancer burden.

Prophylactic Human Papillomavirus Vaccination: From the Origin to the Current State.

Immunization is the most successful method in preventing and controlling infectious diseases, which has helped saving millions of lives worldwide. The discovery of the human papillomavirus (HPV) infection being associated with a variety of benign conditions and cancers has driven the development of prophylactic HPV vaccines. Currently, four HPV vaccines are available on the pharmaceutical market: Cervarix, Gardasil, Gardasil-9, and the recently developed Cecolin. Multiple studies have proven the HPV vaccines' safety and efficacy in preventing HPV-related diseases. Since 2006, when the first HPV vaccine was approved, more than 100 World Health Organization member countries reported the implementation of HPV immunization. However, HPV vaccination dread, concerns about its safety, and associated adverse outcomes have a significant impact on the HPV vaccine implementation campaigns all over the world. Many developed countries have successfully implemented HPV immunization and achieved tremendous progress in preventing HPV-related conditions. However, there are still many countries worldwide which have not created, or have not yet implemented, HPV vaccination campaigns, or have failed due to deficient realization plans associated with establishing successful HPV vaccination programs. Lack of proper HPV information campaigns, negative media reflection, and numerous myths and fake information have led to HPV vaccine rejection in many states. Thus, context-specific health educational interventions on HPV vaccination safety, effectiveness, and benefits are important to increase the vaccines' acceptance for efficacious prevention of HPV-associated conditions.

Vaccination Coverage Against Human Papillomavirus in Female Students in Cyprus.

BackgroundHuman papillomavirus (HPV) has been associated with the development of several cancers and cardiovascular diseases in females. Nevertheless, there is still poor data on vaccination coverage against HPV in several countries, including Cyprus. The main target of the present research was to assess the vaccination status of female students in Cyprus.MethodologyAn online survey was conducted via a cloud-based short questionnaire on Google Forms. Students with a known email address were initially invited via email to complete the survey. The questionnaire was distributed to 340 students, aged 18-49 years old, who lived in Cyprus (60% response rate).ResultsThe total vaccination coverage was 38.1%. The mean age of participants was 23.5 (±6.5) years. The major reason for non-vaccination was the belief that participants were not at risk of serious illness from HPV infection (22%), followed by the reported lack of time to get vaccinated (16%) and inertia (13%). The students who had information about the safety of HPV vaccines from electronic sources of information (television, websites, and blogs) had lower vaccination coverage compared to those who had received information from alternative sources (primary health centers, family doctors, or obstetricians) (relative risk (RR) = 1.923, 95% confidence interval (CI) = 0.9669-3.825; p = 0.033). No significant differences in vaccination rates between participants who were coming from schools of health sciences versus those from financial schools (RR = 1.082, 95% CI = 0.7574-1.544; p = 0.3348) were observed.ConclusionsPublic health policy interventions and education on HPV vaccines are effective ways to improve the awareness and acceptance rate of HPV vaccination among female students and improve the HPV vaccination coverage level in Cyprus.

HPV VACCINATION ROLE IN CERVICAL CANCER ELIMINATION:&#x0D; A LITERATURE REVIEW

Relevance: Cervical cancer (CC) is a socially significant disease in the development of which the human papillomavirus (HPV) plays a central&#x0D; role. HPV is the most common sexually transmitted virus, affecting 80% of sexually active men and women by age 45. Since 2017, the World Health&#x0D; Organization has recommended that all countries implement HPV vaccination programs to reduce and eliminate CC.&#x0D; The study aimed to examine the role of HPV vaccination in eliminating CC over the past decade.&#x0D; Methods: The literature search was done in the PUBMED, MEDLINE, and Cochrane databases for the last ten years using the keywords&#x0D; «cervical cancer,» «vaccination,» and «human papillomavirus.» The review included the results of randomized studies and meta-analyses.&#x0D; Results: The literature provides evidence of the effectiveness and safety of HPV vaccination in countries that have introduced HPV vaccine&#x0D; immunization. The compelling evidence for the effectiveness of HPV vaccination in preventing HPV urge to move from control to elimination of&#x0D; HPV-related diseases.&#x0D; Conclusion: CC is only cancer that can be prevented by vaccination. The development of HPV vaccines and the introduction of HPV immunization into national vaccination schedules helped many countries reduce HPV prevalence and thus reduce HPV incidence.

Encouraging improvement in HPV vaccination coverage among adolescent girls in Kampala, Uganda.

WHO recommends vaccination against HPV for girls before sexual debut. Uganda started HPV vaccination in 2008 as pilot programs in 2 districts, followed by national roll out in 2015. Despite the availability of vaccines against human papillomavirus (HPV) in Uganda in the period covered by the study, there was reported low HPV vaccine uptake and completion especially of the second dose in Uganda; with little information available on timely completion of HPV vaccine and the associated factors in Uganda. This study was therefore done to determine the HPV vaccine dose 2 completion and describe the possible factors associated with timely HPV vaccine completion and non-completion among girls of age 9-14 years attending the adolescent clinic at Mulago hospital. A retrospective mixed methods study was conducted in Mulago National Referral hospital adolescent clinic. Data were mainly collected through review of charts and folders for clinic attendance by eligible girls and focus group discussions with eligible girls that completed the 2 doses of HPV vaccine on recommended/scheduled time. Out of the 201 girls studied, 87 girls (43.3%) had timely completion of the HPV vaccination. Knowledge about HPV infection and HPV vaccine benefits, positive peer influence and healthcare worker recommendation to get vaccinated at health facility level positively influenced timely completion of HPV vaccine. Among barriers to completion of HPV vaccine identified were: inadequate information about HPV infection and HPV vaccine, concerns about HPV vaccine efficacy and safety, unclear communication with adolescents/caregivers from healthcare workers and -stock out of the HPV vaccine. Timely completion of the second dose of HPV vaccine among girls attending the adolescent clinic of Mulago hospital was low (at 43.3%) but higher when compared to earlier published reports. Interventions around improved social mobilization, enhanced outreach and static vaccination approach and education of eligible girls on HPV vaccination can help increase vaccine uptake.

Knowledge, Attitudes and Practices towards Human Papillomavirus (HPV) Vaccine &amp; Prevention of Cervical Cancer among Women Attending Primary Health Care

Background: Cervical cancer is projected to affect 528,000 people worldwide each year. It is the third leading cause of mortality from cancer in developing nations. HPV vaccination was first introduced in 2006, targeting females between the ages of 9-14 years with the aim of preventing HPV that cause cervical precancerous lesions and cancer. Methods: A cross-sectional descriptive study Among Females Attending Primary Health care in AL-Madina AL-Munawarah. All females attending primary health care centers aged 21-65 years or Al-Madina Al-Munawarah. Sample size was 375. The sample size calculated By using Epi-Info version 3.5.1. The study was started after the approval comes from the research committee at Al-Madina region. The researcher took a consent form from the program director of joint program of family medicine and taken it to MOH in Al-Madina City. One primary healthcare center was chosen from each sector. Results: In this study 400 questionnaires were distributed in which 345 participants and response rate was 86.25%, all of them were female and ranged in age from 14 to 65 years. The majority of participants, 112 (32.5%), were between the ages of 26 and 35 years. The majority of participants 222 (64%) were married, Inquiring as to whether you've heard that HPV can cause cervical cancer. 253 respondents said that they had not heard of it. 17% were unaware that HPV is a virus that is transmitted by sexual contact. 7.8% feel it is widespread in Saudi Arabia. 11.9% believe that both men and women are susceptible to infection. 22% that risky sex can raise one's risk of contracting HPV. The majority of individuals expressed concern about the vaccination's negative effects. 250 out of 388 respondents expressed concern about the immunizations' negative effects. Concerning vaccination decisions, 196 believe they should be decided by the individual concerned, while 92 believe they should be made jointly by parents and the individual. Conclusion: Funding for volunteer groups/non-governmental organizations working in the health sector to raise awareness about cervical cancer among healthcare practitioners and the general public might contribute to further reduce the disease's incidence. Public health education is urgently required on the safety and effectiveness of HPV vaccination.

119 Recruiting rural clinics to participate in an HPV vaccination intervention: protocol for a feasibility study and subsequent effectiveness trial

OBJECTIVES/GOALS: Rural teens have lower human papillomavirus (HPV) vaccination rates than urban teens, promoting geographical cervical cancer disparities. Giving HPV vaccination earlier than the recommended 11-12 years might increase vaccination rates. We describe a feasibility study for recruiting rural clinics to participate in early HPV vaccination studies. METHODS/STUDY POPULATION: Leveraging professional contacts, we identified two clinics in North Carolina that serve predominantly rural populations. To assess the feasibility of adapting clinic monitoring systems to promote early vaccination, we requested to review electronic medical records (EMR) to identify the size of the vaccine-eligible patient population, HPV vaccination coverage, and the accuracy of EMR queries to monitor HPV vaccination status. Next, we completed in-depth interviews with clinic staff to collect insights on perceived advantages and disadvantages of promoting early HPV vaccination at 9-10 years, and potential facilitators and barriers to doing so. RESULTS/ANTICIPATED RESULTS: We expect that existing clinic systems will easily accommodate early recommendation and administration of HPV vaccine by expanding EMR queries and vaccination status indicators to include 9- and 10-year-olds. Clinics that are interested in promoting early HPV vaccination can use these adapted tools to monitor vaccine coverage over time. From in-depth interviews we expect to encounter a mix of support and hesitation to promote early HPV vaccination, based on personal beliefs on safety and effectiveness of HPV vaccination, perceptions of adolescent HPV risk, perceptions of parental acceptability of HPV vaccination, and perceived burden of changing current clinic protocols. DISCUSSION/SIGNIFICANCE: This feasibility study’s findings will help determine clinic readiness to recommend early HPV vaccination, and intervention components that maximize staff acceptability of early HPV vaccination. A subsequent randomized effectiveness study will evaluate early HPV vaccination as a method to increase rural adolescent vaccination coverage.
