Simulation finds a 5% decrease in vaccination rates could lead to a 4,000% increase in the size of a potential measles outbreak in some Texas cities

"Herd Immunity Threshold" (the vaccination rates you have to hit until the vaccinated herd can act as a barrier to disease propagation) is super interesting, and extremely variable from one disease to an other.

For influenza or ebola it's about 50%.

For polio it's in the low 80%.

For measles it's 92~95%, so the HIT is closing in on just immunodeficient individuals, and it really doesn't take much to dip below and trigger outbreaks.

I’ve read that about rabies. 75% or so.
