🧵1/ The half-life of a grudge. Britain crushed the 1857 revolt in northern India with mass reprisals centered on Lucknow. For decades after, districts closer to that violence vaccinated their children less against smallpox and the effect faded as the generation that lived through 1857 died off.

Trump’s new approach to global health is “extractive bilateralism”—he will only continue funding HIV medicines or other life saving treatments in a partner nation in exchange for that nation’s minerals or health data. It’s inhumane. I wrote about that for @bmj.com: www.bmj.com/content/bmj/...

Federal kindergarten vaccination data shows national rates for four major vaccines, which had held steady before the COVID-19 pandemic, have fallen significantly since. In fact, measles vaccination rates were below herd immunity in most states in 2023. ➡️ Read more: propub.li/40KnM8n
A U.S. tile map that depicts the measles vaccination rate for kindergarteners (according to CDC data) in each state from 2013 to 2023. A key explains that for each state, a gray dotted line represents the benchmark for herd immunity: a 95% vaccination rate. Vaccination rates above 95% are shown in blue, while vaccination rates below 95% are shown in orange. Looking at the full map, the trend lines lean much more orange than blue. Measles vaccination rates in most states were below herd immunity in school year 2023-2024.

The university of California is a powerhouse of innovation, healthcare, and social mobility for California and the US.
Federal investment in UC research Federal funds are the university’s single most important source of support for research, accounting for more than half of UC’s total research awards.

Many of California’s leading industries grew from UC research, including biotechnology, computing, semiconductors, telecommunications and
agriculture.

Providing health care at UC University of California Health (UC Health) is one of the nation’s largest public academic health systems, serving

Heatmap of the number of cases of measles from the 1920s to the 2010s in the United States, shown by stage. Blue is low, red is high. The chart is annotated with a black line that shows the date of the introduction of the vaccine (approx 1963) and the number of cases drops dramatically right after.Heatmap of vaccines reduced measles cases across US states
From 1929 to 2022
There are lots of cases before 193, then it drops and almost disappears completely in the 1990s.

1963: The first measles vaccine is developed by John Enders
1971: The measles-mumps-rubella (MMR) vaccine is developed by Maurice Hilleman
1980: It becomes mandatory for children entering kindergarten to be vaccinated against measles
