Summary: This study investigated the prevalence and determinants of influenza vaccination hesitancy among the Chinese elderly. The results showed that elderly individuals with higher education levels and from urban areas had higher levels of vaccine hesitancy. Only a minority of the respondents considered themselves as the priority group for influenza vaccination, and a minority reported receiving vaccination recommendations from healthcare workers.

Summary: There is a high prevalence of hesitancy towards influenza vaccination among Chinese elderly, especially those who are well-educated and living in urban areas. The government should address vaccine hesitancy through culturally appropriate communication, subsidies for vaccination, and actively promoting vaccines through primary care professionals.

Summary: The study provides evidence that dual influenza and pneumococcal vaccination is a cost-effective disease prevention strategy for the elderly in Shenzhen, China. It significantly reduces the incidence of influenza and pneumococcal infections and achieves good cost-effectiveness within 5 years.

Summary: The study found that intradermal (ID) administration of influenza vaccines is more immunogenic in the elderly compared to intramuscular (IM) or subcutaneous (SC) routes, offering a potential solution to the decline in immunogenicity observed in this age group. Additionally, the main benefit of ID influenza vaccine lies in its dose-sparing effect, although it may cause more frequent but mild local adverse reactions.

Summary: This study investigated the impact of free vaccination policy on influenza vaccination behavior of the elderly in Zhejiang Province, China. Results indicated that factors such as the policy itself, positive vaccination awareness, frequency of catching cold, and having relatives of healthcare workers significantly influenced the vaccination behavior of the elderly.

Summary: This study compares three different influenza vaccination strategies for the elderly population aged 65 years and older in South Korea. The results indicate that the adjuvanted quadrivalent influenza vaccine (aQIV) is more effective in reducing the burden of influenza-associated disease compared to the standard-dose quadrivalent influenza vaccine (QIV) and high-dose QIV (HD-QIV). The switch from QIV to aQIV is predicted to significantly reduce the number of influenza cases, complications, hospitalizations, and deaths.

Summary: This study investigated the uptake status and factors influencing childhood influenza vaccination in China during the COVID-19 pandemic. The adoption of nonpharmacologic interventions (NPIs) during COVID-19 reduced the risk of influenza infection for children. Many caregivers lacked confidence in the effectiveness and importance of the vaccine, and communication about vaccines between caregivers and healthcare workers was inadequate. Access to vaccination services was also hindered by conflicts with caregivers' schedules and high vaccine prices.

Summary: H9N2 avian influenza virus is prevalent in China, causing economic losses in poultry and posing a threat to public health by infecting humans. Current inactivated whole-virus vaccines can alleviate clinical symptoms but fail to prevent infection completely. Therefore, a more effective vaccine prevention strategy is needed to control the spread of H9N2 avian influenza virus.

Summary: This study investigated the coverage of influenza and other prophylactic vaccines in patients undergoing allergen immunotherapy (AIT) and the attitudes of physicians towards vaccinations in this group. The findings showed a decrease in influenza vaccine uptake after the start of AIT, and most doctors believed that prophylactic vaccinations during AIT are safe and effective.

Summary: This study investigated changes in attitudes, perceptions, and practices regarding influenza vaccination in the Spanish adult population during the COVID-19 pandemic. It found an increase in vaccine confidence, social responsibility, and awareness of the importance of vaccination due to COVID-19 in the 2022/23 season. Advanced age, belonging to high-risk groups, and prior vaccination were significant predictors for the intent to receive the influenza vaccine.

Summary: This study examined influenza vaccination coverage and factors influencing vaccination uptake among children in three Chinese provinces. The findings revealed that the province of residence, educational level, annual income, confidence in vaccine, and vaccine uptake among others were associated with childhood influenza vaccination. Furthermore, access to vaccination services also played a role in vaccination rates. To promote childhood influenza vaccination, public health information campaigns should target caregivers with lower education levels and increase accessibility to vaccination services, while encouraging healthcare workers to promote vaccination.

Summary: This study investigates the influence of digital media exposure on people's intention to get vaccinated against influenza. The findings show that digital media exposure significantly influences the susceptibility and severity of influenza. After exposure to digital media, people tend to have a better understanding of the vaccine's benefits, fewer barriers to vaccination, and a higher intention to get vaccinated.

Summary: This study investigated the practices, knowledge, and attitudes of Italian healthcare workers (HCWs) regarding influenza vaccination during pregnancy. The findings revealed that a significant number of HCWs had misconceptions about the risks of vaccines and lacked up-to-date knowledge. These findings are valuable for promoting evidence-based recommendations among HCWs.

Summary: In China, HPV vaccines have low uptake and are not mandatory. A study was conducted to assess the impact of different messages about the HPV vaccine on willingness to accept it, taking into account parental sociodemographics and the age/gender of a child. The study found that messaging had some limited impact, with parents more likely to accept the vaccine for a daughter and an older child, and certain messages increasing willingness to vaccinate a son or daughter of a specific age.

Summary: This study examines the coverage of mandatory and non-mandatory vaccines in children in Shanghai, China, and investigates the relationship between vaccine hesitancy among young parents and their child's eventual vaccination status. The results show that vaccine hesitancy is associated with lower uptake of non-mandatory vaccines, but not mandatory vaccines. This suggests that Shanghai has a robust system for ensuring high coverage of mandatory vaccines, but if vaccine hesitancy increases, it could affect the coverage of non-mandatory vaccines.

Summary: After the relaxation of mask guidelines, the rate of mask wearing decreased, both among vaccinated individuals and unvaccinated individuals. Vaccinated individuals had higher odds of wearing a mask at work/school (OR: 2.35, 95% CI: 1.82, 3.04) and at a grocery store (OR: 1.65, 95% CI: 1.29, 2.11) compared to the unvaccinated.

Summary: This study examined the associations between multimorbidity at the COVID-19 pandemic onset and longitudinal trajectories of depressive, anxiety, and loneliness symptoms in middle-aged and older adults. Results showed that multimorbidity was linked to elevated depressive and anxiety symptoms at baseline, with symptoms worsening in the first 6 months of the pandemic but improving thereafter. Multimorbid individuals experienced faster changes in anxiety and loneliness symptoms, maintaining elevated mental health issues throughout the follow-up period.

Summary: Although COVID-19 vaccinations have been available to hospital workers in the U.S. since December 2020, coverage is not universal, even among those with patient contact. This study aimed to describe the COVID-19-related experiences of healthcare workers and assess their relation to vaccination. The findings showed that personal experiences with family members and friends were associated with vaccination intent through changes in risk perceptions.

Summary: This study investigated the willingness to pay (WTP) for booster doses of COVID-19 vaccines in Indonesia. The majority of respondents were willing to pay for the booster doses, and factors such as age, education level, income, knowledge about the importance of booster doses, and having a halal certified vaccine status were associated with higher WTP. The findings can be used to develop a pricing scheme for booster doses and may have implications for other low-income countries.
