US study shows updated COVID vaccines cut hospitalization odds by 55%

The 2025-2026 COVID-19 vaccines were associated with 50% estimated effectiveness against COVID-19-associated emergency department and urgent care encounters among immunocompetent US adults. They were also linked to an estimated 55% effectiveness against COVID-19-associated hospitalization, providing added protection beyond existing immunity from prior infection or vaccination.

New vaccines successfully boost frontline immune cells against HIV

T-cells are the immune system's frontline defenders with a crucial role in controlling HIV. In a milestone clinical trial published in the Journal of Clinical Investigation, researchers with the UNC Institute for Global Health and Infectious Diseases (IGHID) at the UNC School of Medicine have demonstrated that new vaccines can significantly boost T cells targeting the most vulnerable, conserved regions of HIV-areas considered key to effective immune control.

Emergency departments could help boost annual flu vaccination rates

A University of California, Riverside-led study of more than 3,200 emergency department (ED) patients across the United States found that while awareness of influenza vaccination is widespread, most adults seen in EDs are not up to date on their annual flu vaccine.

Houston Methodist study reveals how strep bacterium causes infection

A fast-rising strep bacterium has become increasingly notorious for causing serious infections in humans, including complications that can lead to muscle damage and patient death. New Houston Methodist research appearing in The American Journal of Pathology, published by Elsevier, sheds light on how Streptococcus dysgalactiae subspecies equisimilis (SDSE) causes disease and may provide important insights to aid in vaccine development.

Maternal RSV vaccine shows 68% protection against infant RSV hospitalization

In a test-negative case-control study of 274 hospitalized infants aged 90 days or younger, maternal RSVpreF vaccination was associated with 67.6% effectiveness against RSV-associated acute respiratory illness hospitalization. Protection was similar against RSV-linked lower respiratory tract disease, with the highest point estimate in the first month of life, although confidence intervals were wide.

Australia’s diphtheria outbreak shows why boosters, antibiotics, and better housing all matter

A 131-case diphtheria outbreak in Australia’s Northern Territory showed how toxigenic Corynebacterium diphtheriae can re-emerge even in highly vaccinated populations. Genomic and epidemiological evidence linked most cases to a dominant ST381 strain, with transmission shaped by overcrowding, poor skin health, and persistent health inequities.
