We examined whether PTSD (or Major Depression) predicted Mild Cognitive Impairment in Firefighters who responded to the WTC attacks. We found it matters! But also that PTSD only explains about 10% of impairment. www.sciencedirect.com/science/arti...

Measles requires 95% vaccination rates for herd immunity.
It has a 16.2% case fatality rate for unvaccinated children under 5 years and 24% for children under 9 months (who are unable to be vaccinated).
30% of the survivors experience severe complications like blindness, deafness, or encephalitis.

These are the vaccination rates of kindergartners by state. It takes 95% coverage of MMR vaccine to prevent measles outbreaks & most states are not achieving it. I fear that under the new administration rates will drop even further and we will start to see preventable illness, disability, and death
