The efficacy of BNT162b2 (Pfizer–BioNTech) and CoronaVac vaccines in patients with cancer

Journal of Medical Virology, 2022
AbstractAlthough vaccination is efficacious and prevents infection in the general population, there is limited data about Coronavirus disease‐19 (Covid‐19) occurrence after vaccination in cancer patients. It was aimed to evaluate the efficacy of BNT162b2 (Pfizer–BioNTech) and CoronaVac vaccines against Covid‐19 in patients with cancer.

Quantifying Heterogeneous Impacts of Geolocated mHealth Tracing on Spatiotemporal Transmission of Emerging Infections

GeoHealth, Volume 10, Issue 8, August 2026.
Abstract Digital health tools, including mobile device location‐based health (mHealth) applications, have been adopted to augment conventional contact tracing during recent epidemics and pandemics, yet quantitative evidence about their added epidemiological value remains limited. Using aggregated, privacy‐preserving mHealth data from six Chinese cities

Immune Dysregulation in Branched Chain Organic Acidemias

Journal of Inherited Metabolic Disease, Volume 49, Issue 4, July 2026.
ABSTRACT Organic acidemias (OAs) are a group of inherited disorders, most commonly caused by defects in mitochondrial enzymes involved in amino acid and fatty acid metabolism. While they characteristically present with metabolic and neurological crises, growing evidence reveals a significant burden of chronic immune dysregulation in some disorders and ...

Immunosenescence and Vaccine Efficacy in Aging: Dynamic Interplay of Gut Microbiota and mTOR Signaling Pathways

Aging Cell, Volume 25, Issue 6, June 2026.
Aging impairs vaccine efficacy through gut microbiota dysbiosis and mTOR hyperactivation, which together drive inflammaging and weaken immune memory. This review highlights the bidirectional microbiota–mTOR axis and proposes that combining mTOR inhibitors with microbiota modulation offers a promising strategy to enhance vaccine responses in older ...
