Overview of CHIC symposia series: Summary of Africa and South Asia symposia.

This article presents an overview of the main challenges and lessons learned that were presented during the symposia organized by the Coalition to Strengthen the HPV Immunization Community (CHIC) in Africa and South Asia in 2022. Discussions at these meetings revolved around introduction, planning, implementation, and sustainability of HPV prevention and control programmes, with a particular focus in HPV immunisation, as well as cervical cancer screening in South Asian countries. This article also discusses the recently endorsed off-label single-dose HPV vaccination schedule and its potential impact on programme delivery and access.

Effective communication by health care workers to promote HPV vaccination: Lessons learned from Kenya, India, and Nigeria.

Health care workers play an essential role in maintaining the public trust in vaccination programmes globally, and more specifically, in low- and middle-income countries. This role is particularly important in building trust in the human papillomavirus (HPV) vaccine. While there are many factors that affect HPV vaccine acceptance, health care workers are one of the most critical influences in the decision-making process among parents as well as adolescent girls.

Evidence for an HPV one-dose schedule.

The World Health Organization has recently updated their dosing schedule recommendations for the human papillomavirus (HPV) vaccine to include a single-dose schedule. We review the biologic plausibility of a single dose, the evidence from clinical trials, post-licensure observational studies, and mathematical modeling for a single-dose schedule. We also discuss the implications of countries switching to a single-dose program from a two or three-dose schedule.

Status of HPV disease and vaccination programmes in LMICs: Introduction to special issue.

Sexually transmitted human papillomavirus (HPV) infections are extremely common in both men and women and while most will clear naturally, some may progress to cervical cancer and other cancers. Despite the availability of prophylactic vaccines and well-established screening and treatment practices, the global burden of HPV-related disease remains high, particularly in low-and-middle-income countries (LMICs). We outline the current global epidemiology of cervical cancer disease incidence and mortality, with the highest burden in Africa and Asia.

Vaccine decision-making among pregnant women: a protocol for a cross-sectional mixed-method study in Brazil, Ghana, Kenya and Pakistan.

Maternal immunization is a critical strategy to prevent both maternal and infant morbidity and mortality from several infectious diseases. When the first COVID-19 vaccines became available during the pandemic, there was mixed messaging and confusion amongst the broader public and among those associated with health care systems about the recommendations for COVID-19 vaccinations in pregnancy in many countries. A multi-country, mixed-methods study is being undertaken to describe how vaccine decision-making occurs amongst pregnant and postpartum women, with a focus on COVID-19 vaccines.

COVID-19 Vaccination in Historically Marginalized Communities: Examining Barriers and Facilitators in a Pediatric Population.

Introduction: COVID-19 hospitalization rates among unvaccinated children are double of that of vaccinated children, and this difference is greater among racial and ethnic minority children. Vaccination rates among children remain suboptimal. Few studies have characterized barriers to COVID-19 vaccination among historically marginalized communities.

COVID-19 vaccine preferences for pregnant and lactating women in Bangladesh and Kenya: a qualitative study.

COVID-19 was responsible for more than 7 million deaths globally, as well as numerous morbidities and social and economic effects. While COVID-19 vaccines were seen as a marvel of science by the scientific community, much of the public had concerns related to COVID-19 vaccines, with certain groups-such as pregnant and lactating women-having specific concerns related to vaccine effects on their pregnancy and breast milk. In this qualitative study, we interviewed stakeholders in Bangladesh ( = 26) and Kenya ( = 94) who affect the decision-making process related to COVID-19 vaccine acceptance among pregnant and lactating women.

Mapping the existing body of knowledge on new and repurposed TB vaccine implementation: A scoping review.

There is global consensus on the urgent need for a safe and effective TB vaccine for adults and adolescents to improve global TB control, and encouragingly, several promising candidates have advanced to late-stage trials. Significant gaps remain in understanding the critical factors that will facilitate the successful implementation of new and repurposed TB vaccines in low- and middle-income countries (LMICs), once available. By synthesizing the existing body of knowledge, this review offers comprehensive insights into the current state of research on implementation of these adult and adolescent vaccines.

In response to the pervasive challenges posed by online health misinformation, our objective was to develop a training program aimed at enhancing the skills and confidence of healthcare workers in recognizing and effectively responding to misinformation, with a particular focus on vaccinations. This article discusses the design of a training program aimed at equipping healthcare workers with the skills to combat health misinformation, offering theoretical foundations for integrating evidence-based strategies into problem-based learning to help learners retain and apply information, and also shares examples and insights gained from its application across diverse learner groups. The training curriculum integrates evidence-based misinformation intervention strategies, learner engagement strategies and draws from authentic scenarios across diverse cultural contexts.

Lessons from a decade of adult vaccine rollout in low- and middle-income countries: a scoping review.

Introduction: The historical focus of vaccines on child health coupled with the advent of novel vaccines targeting adult populations necessitates exploring strategies for adult vaccine implementation.

Areas Covered: This scoping review extracts insights from the past decade's experiences introducing adult vaccines in low- and middle-income countries. Among 25 papers reviewed, 19 focused on oral cholera vaccine, 2 on Meningococcal A vaccines, 2 on tetanus toxoid vaccine, 1 on typhoid vaccine, and 1 on Ebola vaccine.

Understanding Kenyan policymakers' perspectives about the introduction of new maternal vaccines.

New vaccine policy adoption is a complex process, especially in low-and-middle-income countries (LMICs), requiring country policymakers to navigate challenges such as competing priorities, human and financial resource constraints, and limited logistical capacity. Since the Expanded Programme on Immunization's (EPI) beginning, most new vaccine introductions under this structure have not been aimed at adult populations. The majority of adult vaccines offered under the EPI are not typically tested among and tailored for pregnant persons, except those that are specifically recommended for pregnancy.

The second annual Vaccination Acceptance Research Network Conference (VARN2023): Shifting the immunization narrative to center equity and community expertise.

Promoting vaccine acceptance and demand is an essential, yet often underrecognized component of ensuring that everyone has access to the full benefits of immunization. Convened by the Sabin Vaccine Institute, the Vaccination Acceptance Research Network (VARN) is a global network of multidisciplinary stakeholders driving strengthened vaccination acceptance, demand, and delivery. VARN works to advance and apply social and behavioral science insights, research, and expertise to the challenges and opportunities facing vaccination decision-makers.

The Emerging Landscape of Social Media Influencers in Public Health Collaborations: A Scoping Review.

Social media content creators or "influencers" are an increasingly influential voice in the public discourse generally, including global perceptions and practices related to health. In response, public health entities are increasingly embracing social media influencers (SMIs) as potential health promotion collaborators. Despite burgeoning interest in the potential of these partnerships, research evaluating this strategy remains limited.

COVID-19 vaccine hesitancy prevalence in Mexico: A systematic review and metanalysis.

Background: Vaccine hesitancy (VH) is a recognized threat to public health that undermines efforts to mitigate disease burden. This study aims to gather available evidence regarding COVID-19 VH in Mexico, estimate the prevalence of VH, and its determinants to inform policymaking in this country.

Methods: Following PRISMA guidelines, a systematic review of the MEDLINE literature, articles that estimated the prevalence of COVID-19 VH in Mexico were included in the analysis to obtain a pooled estimate.

Lessons learned from COVID-19 vaccine acceptance among pregnant and lactating women from two districts in Kenya to inform demand generation efforts for future maternal RSV vaccines.

Background: Respiratory syncytial virus (RSV) is a leading cause of acute lower respiratory infections globally, with most RSV-related deaths occurring in infants < 6 months of age. The highest burden of RSV is in low-and-middle income countries, and in sub-Saharan Africa, RSV may be responsible for almost half of all hospital admissions with severe or very severe pneumonia among infants under 1 year. There is a maternal RSV vaccine on the horizon.

key antecedents and questions for acceptance of a future maternal GBS vaccine: Perspectives of pregnant women, lactating women, and community members in Kenya.

Group B streptococcus (GBS) is a leading global cause of neonatal sepsis and meningitis, stillbirth, and puerperal sepsis. While intrapartum antibiotic prophylaxis (IAP) is a currently available GBS disease prevention strategy, IAP is programmatically complex to implement, precluding use in low- and middle-income countries. In Kenya, 2% of stillbirths are attributable to GBS infection.

Global perspectives of determinants influencing HPV vaccine introduction and scale-up in low- and middle-income countries.

Achieving WHO cervical cancer elimination goals will necessitate efforts to increase HPV vaccine access and coverage in low-and-middle-income countries (LMICs). Although LMICs account for the majority of cervical cancer cases globally, scale-up of HPV vaccine programs and progress toward coverage targets in LMICs has been largely insufficient. Understanding the barriers and facilitators that stakeholders face in the introduction and scale-up of HPV vaccination programs will be pivotal in ensuring that LMICs are equipped to optimize the implementation of HPV vaccination programs.

Leveraging a Peer-to-Peer Approach to Mitigate Vaccine Misinformation and Improve Vaccine Communication During a Pandemic: Experiences From the Development of a Massive Open Online Course.

The COVID-19 pandemic has not only led to massive global mortality and morbidity, but it has also fueled an infodemic of false and misleading information about COVID-19 and vaccines. The spread of misinformation and disinformation on vaccine safety and efficacy has contributed to vaccine hesitancy and distrust of public health institutions and has undermined the public health response to the COVID-19 pandemic. Because communication plays a monumental role in pandemic preparedness, a promising approach to countering the COVID-19 infodemic is empowering peers to serve as trusted messengers to provide accurate information using evidence-based communication approaches.

Characterizing Attitudes Toward Maternal RSV Vaccines Among Pregnant and Lactating Persons in Kenya: Key Considerations for Demand Generation Efforts for Vaccine Acceptance.

This study examined attitudes toward maternal RSV vaccines among pregnant and lactating persons in Kenya. First pregnancy was associated with higher vaccine hesitancy among pregnant and lactating people, and social norms were associated with higher vaccine hesitancy among lactating people. Understanding maternal RSV attitudes is critical for vaccine acceptance.

RSV awareness, risk perception, causes, and terms: Perspectives of pregnant and lactating women in Kenya to inform demand generation efforts for maternal RSV vaccines.

Respiratory syncytial virus (RSV) causes a substantial proportion of acute lower respiratory tract infections (LRTI) among infants. In low- and middle-income countries, RSV may be responsible for approximately 40% of all hospital admissions of infants less than one year. A safe and immunogenic RSV vaccine, given to pregnant persons, is imminent.
