Measles Could Go “Viral” When America was great and measles was common, the US Public Health Service published a weekly report on infections like cholera, plague, and measles. Here is a photo of a 1938 measles report. This is what will happen if immunization rates fall below herd immunity levels.

In 2023, guns continued to be the top cause of death for children. More than cancer. More than car accidents. More than sudden unexplained infant death (SUID). Gun deaths are 100% preventable.

Indirect (facility and admin) costs are real. For 70 years, the US biomedical research enterprise has been structured on recovery of these institutional expenditures. Reduction of indirect costs recovery to 15% will cripple US biomedical research for decades. www.science.org/content/arti...

NIH slashes overhead payments for research, sparking outrage

Move to cut indirect cost rate to 15% could cost universities billions of dollars

It is easy to understand the benefit of a new cure for cancer. It feels like a miracle. Vaccines are different. We will never know if one of us, or one of our loved ones, has been saved from death or severe illness by a vaccine. That's prevention. And it is no less a miracle than a cure for cancer.

It was the CDC's communications that alerted the medical community to the dramatic national increase in M. pneumonia infections this fall. These alerts appropriately reshaped clinicians' approach to management of children and adults with respiratory symptoms. www.sciencefriday.com/segments/wal...

Whooping cough (pertussis) cases 5x higher this year than last! A combo of factors: * normal cyclical swings in infexns * pandemic changes in behavior (masking, distancing), now w/ rebound in cases - although we’re seeing decreases in RSV this year so I’m skeptical * decreased vaxx rates 🧪🩺🛟

nbcnews.com

Whooping cough cases reach highest level in a decade

The U.S. has recorded over 32,000 whooping cough cases this year, compared with around 5,100 as of mid-December last year. Infants are most vulnerable to the bacterial infection.

Percentage of available positions that filled in yesterday’s fellowship match.

Bar chart demonstrating the percentage of fellowship positions filled, by specialty, in the NRMP Fellowship Match on December 4, 2024. In cardiology, hematology-oncology, GI, and rheumatology, 99% of positions filled. In pediatric nephrology, just 37%, and in child abuse pediatrics, just 33% of positions were filled.

The measles vaccine is highly effective in preventing illness, reducing hospitalizations, and preventing death. See graphic from N Engl J Med 2019: 381: 349. Nearly 0.5 million US cases/yr before vaccination. "Those who cannot remember the past are condemned to repeat it." - G. Santayana (1905)
