Vaccines help protect people from infections. However, Coronavirus 2019 (COVID-19) vaccinees often still become infected with COVID-19 variants (breakthrough infections) and may go on to suffer from long COVID symptoms due to short-lasting immunity and less-effective protection provided by available vaccines. Moreover, the current COVID-19 vaccines do not prevent viral transmission and ward off only about 15% of breakthrough infections. To prepare more effective vaccines, it is essential to predict the viral strains that will be circulating based on available epidemiological data. The World Health Organization recommends in advance which influenza strains are expected to be prevalent during influenza season to guide the production of influenza vaccines by pharmaceutical companies. However, future emerging COVID-19 strain(s) have not been possible to predict since no sound epidemiological information has been established. Thus, for more effective protection, immune stimulators alone or in combination with vaccines would be preferable to protect people from COVID-19 infection. One of those remedies would be ginseng, which has been used for potentiating immunity in the past.

Background: Dexamethasone has proven life-saving in severe acute respiratory syndrome (SARS) and COVID-19 cases. However, its systemic administration is accompanied by serious side effects. Inhalation delivery of dexamethasone (Dex) faces challenges such as low lung deposition, brief residence in the respiratory tract, and the pulmonary mucus barrier, limiting its clinical use.

This research investigates the moral frames employed by diverse Chinese-speaking "experts" on their Facebook public pages in relation to COVID-19 vaccines, leveraging Moral Foundations Theory for analysis. The analysis highlights that experts predominantly employ moral frames emphasizing care and authority in communicating COVID-19 vaccines. However, the moral frames of care, loyalty, and fairness are more effective in garnering public support.

Background: Cognitive function decline is a problem in aging people living with HIV (PLWHIV). COVID-19 infection is associated with neuropsychiatric manifestations that may persist. The aim of our study was to evaluate cognitive function in PLWHIV before and after COVID-19 infection.

Human noroviruses (HNoVs) are a leading cause of acute gastroenteritis worldwide, with significant public health implications. In this study, wastewater-based epidemiology (WBE) was used to monitor the circulation and genetic diversity of HNoVs in Rome over an eight-year period (2017-2024). A total of 337 wastewater samples were analyzed using RT-nested PCR and next-generation sequencing (NGS) to identify genogroups GI and GII and their respective genotypes.

Second-generation integrase strand transfer inhibitors (INSTIs) are strongly recommended for people living with HIV-1 (PLWH). The emergence of resistance to second-generation INSTIs has been infrequent and has not yet been a major issue in high-income countries. However, the delayed rollouts of these INSTIs in low- to middle-income countries during the COVID-19 pandemic combined with increased transmission of drug-resistant mutants worldwide are leading to an increase in INSTI resistance.
