CONCLUSION: Ad26.COV2.S vaccination showed a high failure rate in HIV-1-infected patients. Pre-existing immunity against Ad26 could be an important contributor to poor vaccine efficacy in a subgroup of patients.
The SARS-CoV-2 outbreak focused global attention on the shortcomings of the drug discovery process. It led to its acceleration in several areas, particularly in the processes associated with the development and approval of COVID-19 vaccines. This
This study was aimed to determine the efficacy of homologous (only CoronaVac or only Pfizer-BioNTech) and heterologous (CoronaVac and Pfizer-BioNTech) vaccines during the period when the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2)
CONCLUSIONS: Esculin inhibits β(2) integrin-dependent neutrophil migration and chemotaxis, blocks the cytoskeletal remodeling process required for neutrophil recruitment, thereby contributing to its protective effect against ALI. This study
The high transmissibility of SARS-CoV-2 Omicron subvariants was generally ascribed to immune escape. It remained unclear whether the emerging variants have gradually acquired replicative fitness in human respiratory epithelial cells. We sought to
Influenza outbreaks are associated with substantial morbidity, mortality and economic burden. Next generation antivirals are needed to treat seasonal infections and prepare against zoonotic spillover of avian influenza viruses with pandemic potential
CONCLUSIONS: The failures or rather lack of success in decision making during the pandemic showed that alongside scientific knowledge and the development of health policies, it is necessary to constantly evaluate the measures and decisions from an
While the rapid development of COVID-19 vaccines has been a scientific triumph, the need remains for a globally available vaccine that provides longer-lasting immunity against present and future SARS-CoV-2 variants of concern (VOCs). Here, we
