Introduction
Human Papillomavirus (HPV) is the most prevalent sextually transmitted infection in Bangladesh, affecting both men and women. While the knowledge, attitudes, and practices (KAP) prevalence among women is well-documented, there is a significant gap in understanding men's KAP regarding HPV and its vaccine. In this study, we assessed the KAP of Bangladeshi men regarding HPV and its vaccine.
Methods
We conducted a qualitative cross-sectional study with 30 men aged 16 and above from Dhaka and Barishal in Bangladesh from July 01, 2023, to August 31, 2023. Participants were general population, healthcare workers (HWs) and policymakers. Participants were recruited through purposive sampling and interviewed face to face or via zoom using a semi-structured guide. Data were analyzed using NVivo 14 and thematic content analysis using the Health Belief Model (HBM) as a guide.
Results
We found limited knowledge about HPV and its vaccine among Bangladeshi men, particularly concerning the infection's impact. HWs and policymakers, although more informed, still demonstrated some misconceptions. A general positive attitude towards vaccination was observed, however, cultural, social, and religious factors were identified as barriers to vaccine acceptance. None of the participants had received the HPV vaccine, though some supported female family members were vaccinated.
Conclusions
Targeted interventions including education and awareness campaigns and gender-neutral vaccination programs are necessary to improve HPV prevention efforts in Bangladesh.

Introduction
HIV infection remains a major global public health concern. This study aimed to evaluate second-dose pneumococcal vaccine coverage among people with HIV in Andalusia who received the first dose between January 1, 2014, and March 31, 2022; to describe their clinical and social characteristics; and to identify factors associated with receipt of the second dose.
Methodology
A retrospective cohort study was conducted among adults with HIV vaccinated against pneumococcus in the Andalusian Public Health System between 2014 and 2022. Vaccination coverage was estimated using Kaplan–Meier curves, and factors associated with receipt of the second dose were assessed using Cox regression models.
Results
Of the 4938 participants, 83.9% were men. Coverage of the second dose was 37.2% at one year and 80% by the end of follow-up. No factors were associated with vaccine adherence in women, whereas in men, having sex with men, being treated in a high-resolution hospital, and living in an area in need of social transformation were linked to higher likelihood of receiving the second dose.
Conclusions
These findings highlight the need to strengthen vaccination adherence by addressing both individual and health-system factors, and to develop targeted strategies to improve pneumococcal vaccine coverage among people living with HIV.

Risk communication recommending infection prevention actions could encourage compliance but may intensify conflicts of opinion toward infection prevention actions. This study addressed five reasons that justify vaccination in COVID-19 and examined their impact on compliance intent and opinions as well as on bias in intergroup attitudes based on differences in opinions toward vaccination. The study was designed as four repeated cross-sectional online surveys covering eight countries (Japan, the United Kingdom, the United States, China, Korea, Germany, Italy, and South Africa). The survey periods covered July and October 2023 and January and April 2024 (post-pandemic). A modified Poisson regression analysis was conducted on the effect of justifications on compliance intent, and a multiple regression analysis was conducted on the impact of justifications on the opinions tendency. In addition, multiple regression analysis was conducted on the effect of justifications on intergroup bias based on disagreement, focusing on the vaccine-accepting group. The results showed that justifications for vaccination, such as preventing harm to others, self-protection, reducing the number of infections and deaths in society, and social norms, have ambivalent effects; they tend to promote compliance intent and opinions tendency while worsening attitudes toward those with different opinions about vaccination. However, the justifications because of penalties was confirmed to reduce negative attitudes toward those with different opinions, while not promoting compliance intent or opinions tendency toward vaccination. When risk communication using infection protection and social norm perspectives is conducted, it is important to simultaneously design and advocate interventions to mitigate intergroup conflicts based on opinions toward infection prevention actions.

Since the pandemic began, the COVID-19 vaccination has faced various challenges, including population hesitancy; these can be explained due to multiple factors that require further exploration. This study analyzes factors associated with either the acceptance or rejection of the COVID-19 vaccine as well as the intention to initiate or to complete vaccination schedules in individuals over the age of 18; individuals from eight cities in Colombia. The study encompasses both urban and rural areas, seeking to develop an intervention strategy. A total of 3384 individuals participated in a mixed-methods study which applied the DESVAAC scale and involved focus groups. Results show that only 11.3% of participants were highly motivated, intending to start or to continue vaccination. The health factor was significantly associated with greater intention (p < 0.01) as compared to social or vaccine-related factors. Greater likelihood of vaccination was also associated with higher education (p < 0.01), greater age (p < 0.02), living with people with chronic conditions (p < 0.05), or cohabiting with individuals over 50 years of age (p < 0.028). Family support (82.9%) and observing others vaccinate (74.1%) were key motivators. Paucity of knowledge regarding vaccines was identified as an important factor, while decisions were also influenced by social, family, and health factors. Also, within the context of a pandemic, there were certain mandatory requirements. The study highlights that community leaders, media and cultural aspects significantly influenced the decision to get vaccinated. It is considered essential to strengthen coordinated efforts between government entities, social leaders, and the community; promoting increased training and education in order to support informed decision-making regarding vaccination within the context of social responsibility. Finally, the psychoeducational intervention strategy VACtívate was designed and implemented; targeting healthcare personnel, social leaders, and health authorities in order to better promote informed vaccination.

Group B Streptococcus (GBS) is a significant bacterial pathogen that poses substantial health risks, particularly among neonates and pregnant women. It is responsible for a range of severe infections, including sepsis, pneumonia, and meningitis, which can lead to high morbidity and mortality rates in these vulnerable populations. Therefore, the prevention of GBS and the implementation of necessary measures to prevent its progression to invasive GBS disease are of critical importance. Prior to the introduction of vaccines, intrapartum antibiotic prophylaxis (IAP) was considered the primary preventive strategy, as it effectively reduced the incidence of early-onset GBS (EOGBS) infection, defined as infection occurring within the first seven days of life. Moreover, it has notable limitations. The IAP is not only ineffective in preventing late-onset GBS (LOGBS, manifesting between the eighth day and the first three months of life) infections but also unlikely to prevent neonatal infections associated with stillbirth, preterm birth, or the early postnatal period. The widespread use of IAP may not only contribute to the emergence of antibiotic resistance due to excessive antibiotic exposure, but also exert detrimental effects on the neonatal microbiome. The development of effective GBS vaccines has therefore become a critical priority in modern medicine. This review delves into the intricate and multifaceted nature of GBS vaccines, beginning with an exploration of their antigenic targets. Antigens are fundamental components of vaccines because they stimulate the immune system to recognize and combat pathogens such as bacteria. In the case of GBS, several promising antigens have been identified, including capsular polysaccharides (CPS) and surface proteins. Among these, CPS stand out due to their critical role in enabling the bacterium to evade the host immune response. The article reviews the typical representatives of polysaccharide conjugate vaccines (the 6-valent GBS polysaccharide conjugate vaccine (GBS6)), the CPS-protein conjugate vaccine (semisynthetic carbohydrate-based vaccines), and protein-based vaccines (GBS-NN vaccine). Moreover, the article evaluates the potential impact of GBS vaccines on reducing disease burden. The ultimate objective is to support ongoing efforts in vaccine development aimed at mitigating associated health risks.

The International Vaccine Institute and Gorgas Institute (Gorgas Memorial Institute for Health Studies) organized the first Chikungunya Global Meeting in Panama City, Panama on December 12–13, 2023. Experts represented eight countries: Brazil, Colombia, Dominican Republic, India, Kenya, Panama, Paraguay, and Thailand. The aim of this meeting was for stakeholders to discuss chikungunya disease burden, vaccine deployment strategies, regulatory challenges, and access issues. This meeting highlighted lessons learned from recent chikungunya outbreaks and perspectives on ways forward in chikungunya research. Specifically, the following topics were discussed in the meeting: (i) lessons from recent chikungunya outbreaks and regional perspectives, (ii) chikungunya research priorities, (iii) chikungunya vaccine development, (iv) regulatory approval and pathways, (v) vaccine access, financing, and procurement, (vi) ways forward through a chikungunya vaccine initiative, and (vii) chikungunya research on how to analyse protection and long-term memory. Experts called for investments in vaccine deployment and a better understanding of the long-term economic impacts of chikungunya. Going forward, the experts recommended creation of a global chikungunya vaccine initiative to coordinate research and generate evidence to inform prevention and control programmes of chikungunya outbreaks and introduction of chikungunya vaccination in high-burden settings and regions at risk of chikungunya outbreaks.
