Neonatal BCG vaccination to prevent asthma: Results from the MIS BAIR randomized controlled trial

open access: yesPediatric Allergy and Immunology, Volume 36, Issue 6, June 2025.
Abstract Background Asthma has a significant impact worldwide, but prevention strategies remain limited. We aimed to evaluate the efficacy of neonatal BCG vaccination in preventing asthma by modulating early‐life immunity. Methods The Melbourne Infant Study: BCG for Allergy and Infection Reduction (MIS BAIR) was a phase 3 multicentre randomized ...

Variations in Tropical Cyclone Size and Rainfall Patterns Based on Synoptic‐Scale Moisture Environments in the North Atlantic

open access: yesJournal of Geophysical Research: Atmospheres, Volume 130, Issue 10, 28 May 2025.
Abstract Prior research has shown that tropical cyclone (TC) size, which is integral in determining the spatial extent of TC impacts, is influenced by environmental wind shear and the overall moisture environment. This study considers North Atlantic TCs located within low to moderate wind shear and at least 100 km from major landmasses.
