Background: The emergence of new COVID-19 variants continues to affect healthcare workers (HCWs) and vulnerable populations in the post-pandemic era. This study aims to assess the willingness, perceptions, and factors associated with booster COVID-19 vaccine uptake in this context.
Methods: A cross-sectional study was conducted between October 2023 and May 2024 among Thai adults (>20 years old) in Chiang Mai, Northern Thailand. Participants included HCWs and patients with chronic medical conditions. People who had received a monovalent XBB-derived booster vaccine were excluded.
Results: Data related to a total of 811 participants were analyzed, with 328 from the vulnerable group and 483 HCWs. Willingness to receive the booster was similar in both groups (43.3% in HCWs, 45.0% in the vulnerable group). Low-risk perception (59.6%-83.5%), minimal impact on daily life (60.4%-62.9%), and doubts about booster efficacy (75.9%-81.4%) were prevalent negative thoughts toward the booster. Having received a flu vaccine (aOR 2.1), concerns about the impact on life of COVID-19 (aOR 1.8), and beliefs in booster safety (aOR 1.8) and vaccine effectiveness against severe disease (aOR 2.7) were associated with increased willingness.
Conclusions: Only 44% of participants were willing to receive a COVID-19 booster. Policymakers can use these insights to develop strategies to increase vaccine uptake in the post-pandemic era.

To estimate maternal COVID-19, influenza, and pertussis vaccine uptake during pregnancy by insurance type and identify factors characterizing those vaccinated and unvaccinated. We conducted a US cohort study of pregnant individuals (for pregnancies ending December 11, 2020-September 30, 2022) using insurance claims data. We calculated vaccination probability using Kaplan-Meier methods and identified factors associated with vaccination through binomial regression with inverse probability weights.

Developing ways to predict and encourage vaccine booster uptake are necessary for durable immunity responses. In a multi-nation sample, recruited in June-August 2021, we assessed delay discounting (one's tendency to choose smaller immediate rewards over larger future rewards), COVID-19 vaccination status, demographics, and distress level. Participants who reported being vaccinated were invited back one year later (n = 2547) to report their willingness to receive a booster dose, along with reasons for their decision.

Pompe disease is a tissue glycogen disorder caused by genetic insufficiency of the GAA enzyme. GAA enzyme replacement therapies for Pompe disease have been limited by poor lysosomal trafficking of the recombinant GAA molecule through the native mannose-6-phosphate-mediated pathway. Here, we describe the successful rational engineering of a chimeric GAA enzyme that utilizes the binding affinity of a modified IGF-II moiety to its native receptor to bypass the mannose-6-phosphate-mediated lysosomal trafficking pathway, conferring a significant increase in cellular uptake of the GAA enzyme.

Particle size and surface properties are crucial for lymphatic drainage (LN), dendritic cell (DC) uptake, DC maturation, and antigen cross-presentation induced by nanovaccine injection, which lead to an effective cell-mediated immune response. However, the manner in which the particle size and surface properties of vaccine carriers such as mesoporous silica nanoparticles (MSNs) affect this immune response is unknown. We prepared 50, 100, and 200 nm of MSNs that adsorbed ovalbumin antigen (OVA) while modifying -glucan to enhance immunogenicity.

Introduction: According to the National Institute for Occupational Safety and Health, ensuring influenza vaccination for public transportation drivers is considered a public health objective, given that these drivers are at high risk of contracting influenza. The main purpose of this cross-sectional study is, thus, to evaluate influenza vaccine hesitancy (VH) and its determinants among a representative sample of Lebanese public transportation drivers.
Methods: A survey questionnaire is conducted between January and March 2023, with the participation of a proportionate purposeful sample of 509 drivers from various regions in Lebanon.
