It's really appalling that in the midst of a preventable surge of measles sweeping across several US states, leading national health authorities are not loudly and publicly recommending vaccination.
How many more children need to die for this madness to stop?

Thank you President Jimmy Carter for supporting the eradication of this disease. Amazing!
Only 10 cases of Guinea worm disease were recorded *globally* last year.
It may become the second human disease we eradicate, after smallpox.

The South Carolina measles outbreak is now bigger than last year's Texas outbreak and is happening as the U.S. is poised to lose its measles elimination status. n.pr/46gC8jB
The U.S. will likely lose its measles elimination status. Here's what that means

Hey California,
Check to make sure that you and your children are vaccinated against measles with the MMR vaccine.🧒
Check to make sure that you and your children are vaccinated against measles with the MMR vaccine.🧒
6/ But that protection is fragile. Three converging risks worry me:
🔹A small but real decline in coverage
🔹Pockets of very low vaccination rates (in 5 CA counties, fewer than 90% of kindergarteners are vaccinated)
🔹Rising measles activity nationally, which means more travel-related cases
