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 ...

One‐Year Quality of Life Among Survivors of Hospitalization for Omicron Infection in Brazil: A Multicentre Prospective Cohort Study

Journal of Medical Virology, Volume 97, Issue 11, November 2025.
ABSTRACT The lingering effects of COVID‐19 may impair survivors' long‐term health‐related quality of life (HRQoL). However, multicentre studies focusing on the Omicron variant, particularly in middle‐ and low‐income settings, are scarce. We conducted a prospective cohort study across 24 Brazilian hospitals between December 2021 and March 2024, when ...
