“Polio Vaccine Effectiveness and Duration of Protection
“Two doses of inactivated polio vaccine (IPV) are 90% effective or more against polio; three doses are 99% to 100% effective.
“It is not known how long people who received IPV will be immune to poliovirus, but they are most likely protected for many years after a complete series of IPV.”

Polio would still be running rampant if we had an outbreak today vs. eradication.
These people are shameless in their anti-vax propaganda. It’s beyond disgusting.
