A respiratory syncytial virus vaccine given to older adults remained highly effective at preventing severe illness over 2 RSV seasons, according to a Kaiser Permanente Southern California study. The study offers real-world evidence that the bivalent RSVpreF vaccine continued to protect adults 60 and older from RSV-related hospitalizations and emergency department visits well beyond the ...
When Chance Shipley was finishing high school in Southern California, baseball defined his future. A pitcher with a college scholarship, he was training for the transition to collegiate athletics when he became seriously ill during winter break in December 2019.

A Kaiser Permanente study of nearly 8,000 men shows that in mid- to late 2024, mpox was far more common among men who have sex with men than previously thought. Individuals without symptoms accounted for most infections and likely played a prominent role in transmission, contrary to prior assumptions that people had to be symptomatic ...
Taking doxycycline after sex helped prevent chlamydia and syphilis, but its ability to prevent gonorrhea faded over time as drug‑resistant strains became more common, according to new research. The findings show both the benefits and limits of a prevention strategy now widely used by patients, clinicians, and public health programs to prevent sexually transmitted infection ...
A large study conducted within Kaiser Permanente Southern California found that people with type 2 diabetes who primarily received diabetes self-management education and support were more likely to achieve healthy blood sugar levels than those whose care focused mainly on physician visits. “For people living with type 2 diabetes, this study shows that actively participating ...

The Division of Clinical Trials Research advances medical innovation by supporting evaluation of new drugs, therapies, and devices to prevent and treat health problems. Our physician investigators work with cooperative groups and industry sponsors to conduct clinical trials for investigational drugs, biologics, and devices. In addition, the division develops pragmatic trials that help answer questions about care delivery.
The region has clinical trials programs in oncology (adult, gynecologic, pediatric, and surgical/radiation oncology), urology, gynecology, neurology, dermatology, metabolic diseases, nephrology, ophthalmology, infectious disease, cardiology, hepatology, vascular surgery, and rheumatology. Clinical trials staff support trials at medical centers and medical office buildings throughout the Kaiser Permanente Southern California Region.
