IntroductionHuman papillomavirus (HPV) is the causative agent of nearly all cervical cancers. Despite the proven safety and efficacy of HPV vaccines in preventing HPV-related cancers, the global ...vaccine coverage rate is estimated to only be 15%. HPV vaccine coverage rates are more actively tracked and reported for adolescents 17 years and younger but there is still a critical window of opportunity to intervene and promote HPV vaccination among young adults aged 18–26 years who are still eligible to be vaccinated. This protocol for a qualitative evidence synthesis aims to review perspectives of HPV vaccination among young adults (18–26 years) and identify facilitators and barriers that influence HPV vaccination uptake and decision-making.Methods and analysisSeven databases will be searched from 1 January 2006 to the date of final search. For inclusion, studies must report HPV vaccination perspectives of young adults aged 18–26 years and use qualitative study methods or analysis techniques. Studies will be screened in a two-stage process guided by the eligibility criteria. Final included studies will be evaluated for methodological strengths and limitations using the Critical Appraisal Skills Programme quality assessment tool for qualitative studies. After data extraction, framework analysis will be used to analyse the data applying the socioecological model. Finally, the Grading of Recommendations Assessment, Development and Evaluation - Confidence in the Evidence from Reviews of Qualitative research will be applied to evaluate the confidence in synthesised qualitative findings. The methodology of this review follows the Cochrane Handbook guidelines on qualitative evidence syntheses.Ethics and disseminationFormal ethical approval is not required for this study. Findings will be disseminated through peer-reviewed publications, conference presentations and professional networks.PROSPERO registration numberCRD42023417052.
The BNT162b2 (Pfizer-BioNTech) mRNA COVID-19 vaccine has demonstrated high efficacy in preventing infection with SARS-CoV-2 (the virus that causes COVID-19) in randomized placebo-controlled Phase III ...trials in persons aged 12-17 years (referred to as adolescents in this report) (1); however, data on real-word vaccine effectiveness (VE) among adolescents are limited (1-3). As of December 2021, the Pfizer-BioNTech vaccine is approved by the Food and Drug Administration (FDA) for adolescents aged 16-17 years and under FDA emergency use authorization for those aged 12-15 years. In a prospective cohort in Arizona, 243 adolescents aged 12-17 years were tested for SARS-CoV-2 by reverse transcription-polymerase chain reaction (RT-PCR) each week, irrespective of symptoms, and upon onset of COVID-19-like illness during July 25-December 4, 2021; the SARS-CoV-2 B.1.617.2 (Delta) variant was the predominant strain during this study period. During the study, 190 adolescents contributed fully vaccinated person-time (≥14 days after receiving 2 doses of Pfizer-BioNTech vaccine), 30 contributed partially vaccinated person-time (receipt of 1 dose or receipt of 2 doses but with the second dose completed <14 days earlier), and 66 contributed unvaccinated person-time. Using the Cox proportional-hazards model, the estimated VE of full Pfizer-BioNTech vaccination for preventing SARS-CoV-2 infection was 92% (95% CI = 79%-97%), adjusted for sociodemographic characteristics, health information, frequency of social contact, mask use, location, and local virus circulation. These findings from a real-world setting indicate that 2 doses of Pfizer-BioNTech vaccine are highly effective in preventing SARS-CoV-2 infection among Arizona adolescents. CDC recommends COVID-19 vaccination for all eligible persons in the United States, including persons aged 12-17 years.
What is already known on this topic? In June 2022, COVID-19 vaccines were authorized for use in children aged 6 months–5 years. Intent to vaccinate and vaccination rates in children have been low. ...What is added by this report? During July 2021–May 2022, in a longitudinal cohort of 393 children aged <5 years in four states, parental intent to vaccinate children against COVID-19 and perception of COVID-19 vaccine safety and effectiveness declined over a 3-month period, but intent to vaccinate and perceptions of vaccine safety returned to baseline after 6 months. What are the implications for public health practice? Identifying and addressing barriers to COVID-19 vaccination in children aged <5 years and educating parents about COVID-19 vaccine effectiveness and safety in young children are critical to increasing pediatric COVID-19 vaccination coverage.
Medical male circumcision is now part of a comprehensive approach to HIV prevention. It has been shown that awareness of the protective effect of male circumcision leads to high acceptability towards ...the introduction of medical male circumcision services within countries. The objective of this survey was to identify factors determining awareness of male circumcision for HIV prevention.
We interviewed 452 participants (267 adults >24 years of age; 185 youths 14-24 years) living in three rural Ugandan districts in 2008. Using a standardized questionnaire, we assessed socio-demographic parameters, awareness of MC for HIV prevention, general beliefs/attitudes regarding MC and MC status. Determinants for awareness of MC for HIV prevention were examined with multiple logistic regression models.
Out of all adults, 52.1% were male (mean +/- SD age 39.8 +/- 11 years), of whom 39.1% reported to be circumcised. Out of all youths, 58.4% were male (18.4 +/- 2.5), 35.0% circumcised.Adults were more aware of MC for HIV prevention than youths (87.1% vs. 76.5%; p = 0.004). In adults, awareness was increased with higher educational level compared to no school: primary school (adjusted OR 9.32; 95%CI 1.80-48.11), secondary (5.04; 1.01-25.25), tertiary (9.91; 0.76-129.18), university education (8.03; 0.59-109.95). Younger age and male sex were further significant determinants of increased awareness, but not marital status, religion, district, ethnicity, employment status, and circumcision status. In youths, we found a borderline statistically significant decrease of awareness of MC for HIV prevention with higher educational level, but not with any other socio-demographic factors.
Particularly Ugandans with low education, youths, and women, playing an important role in decision-making of MC for their partners and sons, should be increasingly targeted by information campaigns about positive health effects of MC.
