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. Our study objective was to better understand how lessons learned from the COVID-19 vaccine experience rollout among pregnant and lactating people in Kenya could inform future maternal RSV vaccine rollout. METHODS: This qualitative study interviewed 16 healthcare providers including doctors, nurses, midwives, community health workers, and vaccinators. Participants were recruited from two counties in Kenya and included healthcare providers that served diverse communities. A grounded theory approach was used to analyze the data. RESULTS: As healthcare providers interviewed were instrumental in COVID-19 vaccine rollout among pregnant women in Kenya, they provided lessons learned from the COVID-19 vaccine experience to inform future maternal RSV vaccine rollout. Community sensitization emerged as the most critical lesson learned, including communication, mobilization, and education. Using communication to ensure community awareness of RSV, community awareness of RSV harms and benefits of RSV maternal vaccines, and providing up-to-date, clear information about maternal RSV vaccines emerged as lessons. Related to mobilization, participants identified the need for healthcare providers and community leaders to gain the trust of communities, and the importance of routinizing the vaccine. Finally, for education, participants outlined critical questions patients would have about a maternal RSV vaccine, including those related to vaccine safety concerns, duration of protection, and vaccine dosing. CONCLUSIONS: This is one of the first studies that has examined how lessons learned from the COVID-19 vaccine rollout for pregnant and lactating women can inform the rollout of future maternal vaccines, including an RSV maternal vaccine. As healthcare providers are directly involved in vaccine rollout, their perspectives are crucial for successful vaccine acceptance.

Maternal Immunization Decision-Making Among Pregnant and Lactating People in Kenya: A Qualitative Exploration of Peer Influences on Vaccine Decision-Making for a Future RSV Vaccine.

INTRODUCTION: Respiratory syncytial virus (RSV) is a leading cause of respiratory illness in infants globally, with new maternal RSV vaccines on the horizon. Vaccine decision-making during pregnancy is shaped by individual, interpersonal, community, and societal factors. This study explored key interpersonal influences on maternal vaccine decision-making among pregnant and lactating people (PLP) and community members in Kenya. METHODS: This qualitative study conducted in-depth interviews with six pregnant people, 18 lactating people, and 10 community members in one rural and one urban county in Kenya. Data were analyzed using a grounded theory approach. RESULTS: Participants identified the pregnant person themself, male partners, other family members, peers, and healthcare providers (HCPs) as key influences on the maternal immunization decision-making process. The majority of interviewed PLP believed that decision-making during pregnancy should be left to themselves due to autonomy and their role as the primary caregiver. Community members, including male partners, also identified pregnant people as the key decision-maker. While some PLP said they deferred to male partners to make vaccine decisions, more felt that men were not as informed on maternal and child issues as themselves or other female peers and relatives. HCPs emerged as important influences and information sources for PLP during decision-making. DISCUSSION: Understanding who influences vaccine-decision making during pregnancy will help inform demand generation strategies, and in turn, uptake of future maternal vaccines, including RSV vaccines. Given the strong role HCPs and peers have in the decision-making process, targeting key potential influences is essential to improve vaccine acceptance.

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. To address this gap, we conducted a scoping review to characterize and describe the current landscape of health promotion collaborations with SMIs with a focus on current practices. A search of six electronic databases (PubMed, SCOPUS, Communication & Mass Media Complete, CINAHL Plus, Web of Science, and APA PsycINFO) revealed wide-ranging and inconsistent approaches to these partnerships, including their optimal practices, data reported, and their evaluation criteria. Among the 658 articles initially identified, 15 publications met our inclusion criteria, spanning 7 countries, 8 social media platforms, 11 distinct health topics, and 21 different outcome measures. Basic information necessary for comparing across interventions was often lacking. We noted a lack of consensus on what constitutes an SMI with 53% of included studies lacking any definition or criteria. Although SMIs offer substantial promise as an emerging opportunity for health promotion, particularly for populations that may be otherwise difficult to identify or reach, this review highlights how the current lack of standardized methodologies and metrics prevents meaningful comparisons between collaborations and evaluations of their effectiveness. Based on these findings, we propose four key criteria to aid practitioners in the implementation and evaluation of SMI collaborations.

MomsTalkShots, tailored educational app, improves vaccine attitudes: a randomized controlled trial.

BACKGROUND: Many pregnant women and parents have concerns about vaccines. This analysis examined the impact of MomsTalkShots, an individually tailored educational application, on vaccine attitudes of pregnant women and mothers. METHODS: MomsTalkShots was the patient-level component of a multi-level intervention to improve maternal and infant vaccine uptake that also included provider- and practice-level interventions. The impact of these interventions was studied using a two-by-two factorial design, randomizing at both the patient- and the practice-level. Study staff recruited pregnant women from a diverse set of prenatal care practices in Colorado and Georgia between June 2017 and July 2018. All participants (n = 2087) received a baseline survey of maternal and infant vaccine intentions and attitudes, and two follow-up surveys at least 1 month and 1 year after their infant's birth, respectively. Half of participants (n = 1041) were randomly assigned to receive educational videos through MomsTalkShots, algorithmically tailored to their vaccine intentions, attitudes, and demographics. Since the practice/provider intervention did not appear impactful, this analysis focused on MomsTalkShots regardless of the practice/provider intervention. RESULTS: By 1 month post-birth, MomsTalkShots increased perceived risk of maternal influenza disease (61% among MomsTalkShots recipients vs 55% among controls; Odds Ratio: 1.61, 95% Confidence Interval: 1.23-2.09), confidence in influenza vaccine efficacy (73% vs 63%; OR: 1.97, 95%CI: 1.47-2.65), and perceived vaccine knowledge (55% vs 48%; OR: 1.39, 95%CI: 1.13-1.72). Among those intending not to vaccinate at baseline, MomsTalkShots increased perceived risk of maternal influenza disease (38% vs 32%; OR: 2.07, 95%CI: 1.15-3.71) and confidence in influenza vaccine efficacy (44% vs 28%; OR: 2.62, 95%CI: 1.46-4.69). By 1 year post-birth, MomsTalkShots increased perceived vaccine knowledge (62% vs 50%; OR: 1.74, 95%CI: 1.36-2.24) and trust in vaccine information from obstetricians and pediatricians (64% vs 55%; OR: 1.53, 95%CI: 1.17-2.00). Among those uncertain about vaccinating at baseline, MomsTalkShots increased perceived vaccine knowledge (47% vs 12%; OR: 6.89, 95%CI: 1.52-31.25) and reduced infant vaccine safety concerns (71% vs 91%; OR: 0.24, 95%CI: 0.06-0.98). CONCLUSIONS: MomsTalkShots improved pregnant women's and mothers' knowledge and perceptions of maternal and infant vaccines and the diseases they prevent, and offers a scalable tool to address vaccine hesitancy.

Communication lessons learned from the 2017 measles-rubella campaign in India: perspectives from vaccine decision-makers.

In 2017, to reduce the burden of measles and rubella, a nation-wide measles-rubella campaign was launched in India. Despite detailed planning efforts that involved many stakeholders, vaccine refusal arose in several communities during the campaign. As strategic health communication and promotion is critical in any vaccine campaign, we sought to document lessons learned from the 2017 MR campaign from a strategic health communication and promotion perspective to capture lessons learned. To inform future campaigns, we conducted in-depth interviews through a perspective that is not usually captured, that of government and civil society stakeholders that had experience in vaccine campaign implementation (n = 21). We interviewed stakeholders at the national level and within three states that had diverse experiences with the campaign. Three key themes related to strategic health communication and promotion emerged: the importance of sensitizing communities at all levels through relevant and timely information about the vaccine and the vaccine campaign, leveraging key influencers to deliver tailored messaging about the importance of vaccines and mitigating vaccine misinformation rapidly. Our study findings have important implications for health communication and promotion research related to vaccine campaigns. The field must continue to enhance vaccine campaign efforts by identifying important health communication and promotion factors, including the importance of sensitization, trusted messengers that use tailored messaging and mitigating misinformation, as vaccine campaigns are crucial in improving vaccine acceptance.

Measles and rubella are diseases that cause sickness and death. Both are preventable as there are safe and effective vaccines available. Measles and rubella are significant in India. These vaccines are generally delivered to the public through vaccine campaigns. A measles­rubella vaccine campaign was implemented in 2017. In this study, we interviewed 21 government and civil society stakeholders that are involved in vaccine campaigns in India to capture lessons learned. We were interested in understanding how vaccine campaigns could be improved through health communication and promotion efforts. Stakeholders suggested to use trusted community members to inform people about the vaccine campaign, and that it was important for trusted community leaders to dispel rumors about vaccines quickly. To increase vaccine acceptance, it is critical that health communication and promotion efforts target concerns that people may have about the vaccine as well as the vaccine campaign.

Development of a Scale to Measure Trust in Public Health Authorities: Prevalence of Trust and Association with Vaccination.

Infectious disease outbreaks highlight the importance of trust in public health authorities to avoid fear and improve adherence to recommendations. There is currently no established and validated measure for trust in public health authorities. We aimed to develop and validate an instrument that measures trust in public health authorities and to assess the association between trust in public health authorities and vaccine attitudes. We developed 20 items to measure trust in public health authorities. After implementing a survey in January 2020, we investigated relationships between the items, reduced the number of items, and identified latent constructs of the scale. We assessed variability in trust and how trust was associated with vaccine attitudes, beliefs, and self-reported vaccine acceptance. The pool was reduced to a 14-item trust in public health authorities scale and we found that this trust model was strongly associated with acceptance of vaccines. Our scale can be used to examine the relationship between trust in public health authorities and adherence to public health recommendations. The measure needs to be validated in other settings to determine whether they are associated with other areas where the public question public health authority recommendations.

Perceptions of why Malawians engage in concurrent sexual partnerships among a select population of radio listeners: findings from an exploratory study.

Concurrent sexual partnerships have been identified as a potential driver in the HIV epidemic in Southern Africa. This study utilised an innovative approach to explore perceptions of why Malawians may engage in these relationships, and their suggestions for reducing the practice among a select population of radio listeners. Using radio listener feedback in the form of text messages, we analysed approximately 1 000 text messages sent by individuals who listened to a reality radio programme that included real stories, told by Malawians, on topics related to HIV/AIDS. Listeners suggested that lack of satisfaction with one's partner was the overarching reason why individuals had concurrent sexual partnerships. Within the context of lack of satisfaction, listeners cited alcohol use, poor communication and gendered norms as factors related to satisfaction. Listeners suggested that couple communication could increase satisfaction, which, in turn, could reduce concurrent sexual partnerships. Prevention efforts should consider how to utilise couple communication to improve satisfaction as an approach to reduce HIV risk in Southern Africa.

The Differential Effects of an Opt-Out HIV Testing Policy for Pregnant Women in Ethiopia When Accounting for Stigma: Secondary Analysis of DHS Data.

Individual factors associated with HIV testing have been studied across multiple populations; however, testing is not just an individual-level phenomenon. This secondary analysis of 2005 and 2011 Ethiopia Demographic and Health Survey data was conducted to determine the extent to which the 2007 institution of an opt-out policy of HIV testing during antenatal care increased testing among women, and whether effects differed by women's stigmatizing beliefs about HIV. A logit model with interaction between pre-/post-policy year and policy exposure (birth in the past year) was used to estimate the increased probability of past-year testing, which may be attributable to the policy. Results suggested the policy contributed to a nine-point increase in the probability of testing (95% CI 0.06-0.13, p < 0.0001). A three-way interaction was used to compare the effects of exposure to the policy among women holding higher and lower HIV stigmatizing beliefs. The increase in the probability of past-year testing was 16 percentage points greater among women with lower stigmatizing beliefs (95% CI 0.06-0.27, p = 0.002). Women with higher stigmatizing beliefs were less likely to report attending antenatal care (ANC), testing at their last ANC visit, or being offered a test at their last ANC visit. We encourage researchers and practitioners to explore interventions that operate at multiple levels of socio-ecological spheres of influence, addressing both stigma and structural barriers to testing, in order to achieve the greatest results in preventing HIV.

Voluntary medical male circumcision for HIV prevention and early resumption of sexual activity: a literature review.

A number of programs have focused on scale-up and implementation research regarding voluntary medical male circumcision; however, there is limited research with regard to factors and strategies related to abstinence compliance and the effects of resuming sex during the wound healing period (42-day post-circumcision). We searched the literature for peer-reviewed articles examining early resumption of sex during this period. This review identifies factors that may predispose a client to engage in sex during the 42-day postoperative period, examines how early resumption of sex can inhibit wound healing and increase seroconversion, and reviews strategies that may increase adherence to abstinence during the wound healing period. We found that the most common factor that may predispose a client to engage in sex before the end of the postoperative period is marriage or cohabitation with a sexual partner. With regard to the effect of sex during the postoperative period on wound healing and seroconversion, we found that adverse events incurred were mild, and there was an increased risk of seroconversion. The only strategy studied to increase compliance to abstinence during the postoperative period utilized text messaging, and the trial results indicate that text messaging did not increase abstinence compliance.

Stigma against people with HIV/AIDS in rural Ethiopia, 2005 to 2011: signs and predictors of improvement.

This study sought to determine trends in and factors associated with stigma against people with HIV/AIDS in Ethiopia. Rural data from the 2005 and 2011 Demographic and Health Surveys were analyzed. HIV testing rates among males increased dramatically from 2005 to 2011 (8-35 %). Among females, testing rates dropped 10 % during the same period. HIV knowledge was associated with stigma, shown by a negative correlation in both data waves, but groups with higher knowledge tended to have lower stigma. Lower levels of knowledge were uniformly associated with higher levels of stigma, but higher levels of knowledge, combined with higher levels of education, were associated with lower levels of stigma in a multiplicative way. Improvements in knowledge can serve as an important intermediate process to behavior change. The found interaction suggests improvements in either education or knowledge can reduce stigma, and when both are improved, stigma reduction will be more dramatic.

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. This qualitative study interviewed 13 global stakeholders categorized as either academic partners or global immunization partners to ascertain perspectives regarding factors affecting the introduction and scale-up of HPV vaccination programs in LMICs. Global stakeholders were selected as their perspectives have not been as readily highlighted within the literature despite their key role in HPV vaccination programming. The results of this investigation identified upstream (e.g., financial considerations, vaccine prioritization, global supply, capacity and delivery, and vaccine accessibility, equity, and ethics) and downstream (e.g., vaccine acceptability and hesitancy, communications, advocacy, and social mobilization) determinants that impact program introduction and scale-up and confirmed that strong political commitment and governance are significant in garnering support for HPV vaccines. As LMICs introduce HPV vaccines into their national immunization programs and develop plans for scaling up vaccination efforts, strategic approaches to communications and advocacy will also be needed to successfully meet coverage targets.

"Why has this new vaccine come and for what reasons?" 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. Two maternal GBS vaccines are in late-stage clinical development. However, licensure of a maternal GBS vaccine does not translate into reduction of disease. We conducted 28 in-depth interviews with pregnant people, lactating people, and community members across two counties in Kenya to better understand the attitudes and informational needs of primary vaccine beneficiaries. We identified two emerging themes from the data. The first focused on antecedents to maternal GBS vaccine acceptability. The most common antecedents focused on the vaccine's ability to protect the baby and/or the mother, followed by community sensitization before the vaccine was available. The second key theme focused on questions that would need to be addressed before someone could accept a maternal GBS vaccine. Three key categories of questions were identified, including vaccine safety compared to vaccine benefits, who gets the vaccine, and how the vaccine works. Realizing the potential benefits of a future GBS maternal vaccine will require a multifactorial approach, including ensuring that communities are aware of GBS-related harms as well as the safety and effectiveness of a maternal GBS vaccine. Our study contributes to informing this multifactorial approach by elucidating the attitudes and concerns of key populations.

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. This review explores four key dimensions: (1) epidemiological impact, (2) costing, cost-effectiveness, and/or economic impact, (3) acceptability, and the (4) feasibility of implementation; this includes implementation strategies of target populations, and health system capabilities. Results indicate that current research primarily consists of epidemiological and costing/cost-effectiveness/economic studies in India, China, and South Africa, mainly modelling with M72/AS01, BCG revaccination, and hypothetical vaccines. Varying endpoints, vaccine efficacies, and vaccination coverages were used. Globally, new, and repurposed TB vaccines are estimated to save millions of lives. Economically, these vaccines also demonstrate promise with expected cost-effectiveness in most countries. Projected outcomes were dependent on vaccine characteristics, target population, implementation strategy, timing of roll out, TB burden/country context, and vaccination coverage. Potential barriers for vaccine acceptability included TB-related stigma, need for a second dose, and cost, while low pricing, community and civil society engagement and heightened public TB awareness were potential enablers in China, India, and South Africa. Potential implementation strategies considered spanned from mass campaigns to integration within existing vaccine programs and the primary target group studied was the general population, and adults and adolescents. In conclusion, future research must have broader geographical representations to better understand what is needed to inform tailored vaccine programs to accommodate diverse country contexts and population groups to achieve optimal implementation and impact. Furthermore, this review underscores the scarcity of research on acceptability of new and repurposed TB vaccines and their delivery among potential beneficiaries, the most promising implementation strategies, and the health system capabilities necessary for implementation. The absence of this knowledge in these areas emphasizes the crucial need for future research to ensure effective TB vaccine implementation in high burden settings worldwide.

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. Given that new maternal vaccines, including RSV and GBS vaccines, are on the horizon, it is important to understand what barriers may arise during the policy development and vaccine introduction process. In this study, we sought to understand information needs among maternal immunization policymakers and decision-makers in Kenya for new vaccine maternal policy adoption through in-depth interviews with 20 participants in Nakuru and Mombasa counties in Kenya. Results were mapped to an adapted version of an established framework by Levine et al., (2010) focused on new vaccine introduction in LMICs. Participants reported that the policy process for new maternal vaccine introduction requires substantial evidence as well as coordination among diverse stakeholders. Importantly, our findings suggest that the process for new maternal vaccines does not end with the adoption of a new policy, as intended recipients and various actors can determine the success of a vaccine program. Previous shortcomings, in Kenya, and globally during HPV vaccine introduction show the need to allocate adequate resources in education of communities given the sensitive target group. With maternal vaccines targeting a sensitive group - pregnant persons- in the pipeline, we are at an opportune time to understand how to ensure successful vaccine introduction with optimal acceptance and uptake, while also addressing vaccine hesitancy to increase population benefit.

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. We used a binomial-normal model for meta-analysis of proportions (i.e., generalized linear mixed model) to perform the metanalysis. We then performed a narrative review of COVID-19 VH in Mexican subpopulations. Results: Seven studies met inclusion criteria. We estimated a pooled prevalence of COVID-19 VH of 16 % (95 % CI: 11-23 %) in Mexico. We found an association between VH and demographic characteristics, intrinsic vaccine factors, and beliefs. Subgroup analyses from specific studies suggested that patients with clinical conditions such as breast cancer or rheumatologic diseases had a higher prevalence of VH. Conclusions: VH is a highly complex and dynamic phenomenon in Mexico. Characterizing and understanding COVID-19 vaccine hesitancy in the Mexican population helps target future policy interventions to mitigate the spread and impact of infectious diseases. The implications of VH differ among groups that may be at higher risk of severe disease, underscoring the importance of prompt research among these groups as well as targeted interventions to address VH.

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. Aligned with WHO's Global Framework for New TB Vaccines for Adults and Adolescents, our findings center on vaccine availability, accessibility, and acceptance. EXPERT OPINION: Availability findings underscore the importance of understanding disease burden for prioritization, multi-sectoral collaboration during planning, and strategic resource allocation and coordination. Accessibility results highlight the benefits of leveraging existing health infrastructure and adequately training healthcare workers, and contextually tailoring vaccine delivery approaches to reach challenging sub-groups like working male adults. Central to fostering acceptance, resonant sensitization, and communication campaigns engaging the communities and utilizing trusted local leaders countered rumors and increased awareness and uptake. As we approach the introduction of a new adult TB vaccine, insights from this review equips decision-makers with key evidence-based recommendations to support successful and equitable vaccinations targeting adults.

Descriptive and injunctive norms related to concurrent sexual partnerships in Malawi: implications for HIV prevention research and programming.

Concurrent sexual partnerships are hypothesized to be a contributing factor to Malawi's HIV epidemic. As social norms influence health behavior and have been found to influence sexual behavior, the purpose of this study was to explore two types of norms, descriptive and injunctive norms, toward concurrent sexual partnerships in Malawi. Data from 40 focus group discussions and 20 in-depth interviews conducted in five districts in Malawi, which included 318 participants aged 18-55 years, were analyzed. Participants perceived that concurrent sexual partnerships were extremely common, and believed that very few individuals in their communities were not in concurrent sexual partnerships. However, participants perceived that others in their communities heavily disapproved of concurrent sexual partnerships outside of polygamy, as polygamy was viewed as an acceptable type of partnership because it was conducted in the open. Participants asserted that there were no traditional practices that promoted concurrent sexual partnerships, and perceived that those that engaged in the behavior were for the most part stigmatized by community members. Further research is needed to obtain a thorough understanding of the way in which the perceived actions and beliefs of peers influence the beliefs, feelings and actions of individuals to strengthen HIV programming efforts in the region.

Vaccine Communication: Appeals and Messengers Most Effective for COVID-19 Vaccine Uptake in Ukraine.

Throughout the COVID-19 pandemic, vaccine communication has been a challenge, particularly as some populations may be highly distrustful of information from public health or government institutions. To better understand the different communication needs in Ukraine, an online survey panel of 168 Ukrainian participants viewed six COVID-19 vaccination ads with three variations on vaccine messaging appeals (potential economic impacts of COVID-19 infection COVID-19 disease outcomes, and social norms related to vaccination) and two different messengers (a peer or a health provider). The ad featuring a health outcome appeal delivered by a healthcare provider was most favored (n = 53, 31.6%); however, across demographic categories, including vaccine hesitancy categories, participants expressed high levels of approval for all six variations of the COVID-19 vaccine ads. When participants ranked reasons why someone may not accept the COVID-19 vaccine, the most prevalent beliefs identified were that the vaccine was not safe, and that the vaccine was not effective. Findings from this study suggest that vaccine appeals focused on health outcomes delivered by healthcare providers are preferred by most individuals in Ukraine; however, individuals are motivated by a myriad of factors suggesting that for vaccine messaging to be most effective, communication should be varied in both appeal and messenger.

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. In this qualitative study, we sought to understand factors that could inform maternal vaccine decision-making to inform future demand generation strategies in Kenya. We conducted in-depth interviews with 24 pregnant and lactating persons from two counties, with two communities in each county. Four key themes emerged, including terms used for RSV, awareness of and risk perception related to RSV, causes of RSV, and questions about future maternal RSV vaccines. Regarding terms, no participant used the term RSV to describe the disease. Most participants associated RSV with cold things such as cold weather and cold food/drink. Most participants believed that RSV was caused by the cold or an unclean environment. Finally, key questions related to a maternal RSV vaccine were related to vaccine safety, and more specifically side effects. Questions arose related to vaccine effectiveness as well as timing of administration and dosing. A maternal RSV vaccine is on the horizon. However, vaccines do not save lives; vaccination does. As such, it is critical to develop and implement demand generation approaches to ensure that once a maternal RSV vaccine is available, communities are sensitized and willing to accept it.

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.
