Identification of Clinical Factors Associated With the Immunogenicity of Homologous ChAdOx1‐nCoV‐19 Vaccine in Hemodialysis Patients

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Hemodialysis (HD) patients are at higher risk of severe COVID‐19 and may exhibit suboptimal vaccine responses. This study evaluates the factors influencing vaccine‐induced immunity in HD patients following the second dose of the Vaxzevria. A total of 276 HD patients and 126 controls were included. Antibody responses were assessed using binding

Booster mRNA Vaccination Prevents Breakthrough Severe COVID‐19 Infections

Journal of Medical Virology, Volume 98, Issue 6, June 2026.
ABSTRACT This study aimed to assess the humoral immune response following administration of a BNT162b2 mRNA COVID‐19 booster dose and to evaluate its association with the development of SARS‐CoV‐2 infection after vaccination. Between July 2021 and February 2022, serum samples were collected from 313 individuals 28 days after receiving a COVID‐19 ...

IgA Vasculitis Following ChAdOx1 nCoV-19 Vaccination

APIK Journal of Internal Medicine, 2022
Abstract IgA vasculitis (IgAV), a small-vessel vasculitis, is more frequently seen in children than in adults. IgAV is triggered by various bacterial and viral infective agents. Here, we are describing a case of IgAV following ChAdOx1 nCoV-19 vaccination. A 39-year-old male presented with skin rash, joint pain, and pain abdomen.

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 ...
