Context: Influenza-related hospitalization and mortality disproportionately affects the Hispanic population in the United States. Among other medical conditions in addition to influenza, Spanish-preferring Hispanics may be more affected than those who speak English.
Objectives: The purpose of this study was to compare seasonal influenza vaccine uptake rates between Spanish-and English-preferring Hispanic US adults from 2017 to 2020.
Methods: For this cross-sectional study, we extracted data from the Behavioral Risk Factor Surveillance System (BRFSS) from the 2017 through 2020 cycles. We calculated the population prevalence of individuals getting influenza vaccines per year, and among subpopulations based on language spoken, age, and sex. We then utilized chi-squared tests of independence to discover possible associations between these subpopulations per year. An alpha level of 0.05 was utilized in this study. Respondents were included if they identified as Hispanic, responded to questions regarding influenza vaccine uptake, and were grouped by the language of the survey returned, age, and sex.
Results: Our results show that self-identified Hispanic individuals who were English-preferring had greater seasonal influenza vaccine uptake rates in the latter 2 years of our study for both sexes in the younger age group. Hispanic individuals over the age of 65 years (n=11,328) were much more likely to have received an influenza vaccine compared to younger individuals (n=34,109). In 2018, Spanish-preferring women over age 65 years (n=677) were more likely to have received a vaccine over English-preferring women (n=772).
Conclusions: Our findings showed that disparities exist between English- and Spanish-preferring Hispanic individuals and age groups. Language barriers may play a role in receiving influenza vaccines. The incorporation of medical translators may assist in reducing these disparities in influenza-related healthcare expenses, overall morbidity, and mortality.

Background: Democrats are more likely to be vaccinated for COVID-19 than Republicans. It is unknown if political polarization surrounding the COVID-19 vaccine has affected flu vaccine uptake. The purpose of this study is to examine the partisan differences in annual flu vaccine uptake before and after the COVID-19 pandemic.

In this review, we present the efforts made so far in developing effective solutions to prevent infections caused by seven major respiratory pathogens: influenza virus, respiratory syncytial virus (RSV), the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), , (), , and . Advancements driven by the recent coronavirus disease 2019 (COVID-19) crisis have largely focused on viruses, but effective prophylactic solutions for bacterial pathogens are also needed, especially in light of the antimicrobial resistance (AMR) phenomenon. Here, we discuss various innovative key technologies that can help address this critical need, such as (a) the development of Lung-on-Chip ex vivo models to gain a better understanding of the pathogenesis process and the host-microbe interactions; (b) a more thorough investigation of the mechanisms behind mucosal immunity as the first line of defense against pathogens; (c) the identification of correlates of protection (CoPs) which, in conjunction with the Reverse Vaccinology 2.

Background: Respiratory syncytial virus (RSV) is an important cause of lower respiratory tract infection, hospitalisation and death in adults.
Methods: Based on evidence regarding the impact of RSV on adult populations at risk for severe infection and the efficacy and safety of RSV vaccines, the Portuguese Society of Pulmonology, the Portuguese Association of General and Family Medicine, the Portuguese Society of Cardiology, the Portuguese Society of Infectious Diseases and Clinical Microbiology, the Portuguese Society of Endocrinology, Diabetes and Metabolism, and the Portuguese Society of Internal Medicine endorses this position paper with recommendations to prevent RSV-associated disease and its complications in adults through vaccination.
Conclusion: The RSV vaccine is recommended for people aged ≥50 years with risk factors (chronic obstructive pulmonary disease, asthma, heart failure, coronary artery disease, diabetes, chronic kidney disease, chronic liver disease, immunocompromise, frailty, dementia, and residence in a nursing home) and all persons aged ≥60 years.
Fluorofurimazine, a novel NanoLuc substrate, enhances real-time tracking of influenza A virus infection without altering pathogenicity in mice.

Unlabelled: Bioluminescence imaging (BLI) using engineered bioluminescent viruses has emerged as a powerful tool for real-time, noninvasive monitoring of viral replication in living animals. While traditional luciferase-based systems, such as firefly luciferase, have been widely used, the NanoLuc luciferase system offers distinct advantages, including its significantly smaller gene size, increased brightness, and independence from ATP as a cofactor, allowing for extracellular detection. However, the utility of NanoLuc has been limited by its traditional substrate, furimazine, which exhibits poor water solubility and potential cytotoxicity.
