Why H2N2 flu is back on the pandemic preparedness radar

A historical review in Vaccine warns that global H2N2 immunity has sharply declined since the 1957 Asian influenza pandemic, leaving most people without H2-specific protection if the virus re-emerges. The authors highlight animal reservoirs, waning birth-cohort immunity, and modern H2 vaccine platforms as key priorities for pandemic preparedness.

Twice-yearly blood pressure treatment could reshape hypertension care, but doctors warn against a “fire-and-forget” approach

Long-acting RNA interference therapy for hypertension could shift blood pressure control from daily pill-taking to scheduled, system-led protection. But the authors warn that this “vaccine-like” model must preserve lifestyle support, monitoring, and follow-up to avoid clinical disengagement.

The Big Catch-Up reaches millions of children with life-saving vaccines

The Big Catch-Up (BCU), a historic multi-year, multi-country effort to address vaccination declines driven largely by the COVID-19 pandemic, has reached an estimated 18.3 million children aged 1 to 5 across 36 countries with more than 100 million doses of life-saving vaccines, helping to narrow critical immunity gaps, announced Gavi, the Vaccine Alliance (Gavi), WHO, and UNICEF at the start of World Immunization Week.

Air quality in infancy may fundamentally shape long-term immune development

Ambient air pollution is associated with respiratory infection burden in the first year of life, according to preliminary findings from the Immune Development in Early Life (IDEaL) Rome Cohort. Findings from the cohort will be presented during the Pediatric Academic Societies (PAS) 2026 Meeting, taking place April 24-27 in Boston.

Why Japan saw a major pertussis surge in 2025 while other countries peaked earlier

This study found that pertussis cases fell across Japan, Australia, New Zealand, China, and the USA during COVID-19 restrictions, then resurged afterward, with most countries peaking in 2024 but Japan showing a delayed major outbreak in 2025. In Japan, the surge was concentrated in school-aged children and adolescents, highlighting possible gaps in booster protection and the need to reassess immunization strategies.

Study reveals significant gaps in MMR vaccine knowledge among ER patients

Measles remains one of the most contagious infectious diseases, spread through coughing and sneezing, with even small declines in vaccination coverage leading to outbreaks. As of 2026, California has reported its highest annual measles case count in seven years. In response to this growing concern, researchers have begun examining gaps in measles-related knowledge and vaccination coverage.
