Pre‐Existing Th1 Immunity Outperforms Age in Predicting Antibody Responses to SARS‐CoV‐2 Inactivated Vaccines

Advanced Science, Volume 13, Issue 6, 30 January 2026.
Challenging the focus on age, this study finds pre‐existing T helper 1 cells are the key biomarker for predicting antibody response to SARS‐CoV‐2 inactivated vaccines. In both mice and humans, high responders exhibited elevated baseline T helper 1 cells, which correlated with robust humoral immunity, offering crucial guidance for improving vaccine ...

Kinetics of IgA Subtypes and Cytokines in Respiratory Secretions Following Immunization With COVID‐19 Mucosal Vaccine

Journal of Medical Virology, Volume 97, Issue 10, October 2025.
ABSTRACT The COVID‐19 pandemic highlights the need for mucosal vaccines inducing respiratory secretory IgA (sIgA), as traditional intramuscular vaccines primarily elicit systemic IgG with limited mucosal protection. This study systematically compared mucosal immune responses induced by two authorized COVID‐19 mucosal vaccines: an orally aerosolized ...

Vaccine Induced Immune Thrombotic Thrombocytopenia After Sinopharm Vaccination: A Systematic Review of Case Reports

Clinical Case Reports, Volume 13, Issue 9, September 2025.
ABSTRACT Vaccine‐induced thrombotic thrombocytopenia (VITT) has been linked to vector‐based vaccines, but only four cases following whole‐virus vaccines (Sinopharm) have been reported, as far as we are aware. This systematic review aimed to compile the clinical and laboratory results of VITT development after Sinopharm vaccination.
