Yes, on the polio story. Here's a thought. How up to date is your vaccination card?
Lots of vaccines lose effectiveness over time. If you haven't updated your vaccinations now is a good time to do it.
While you still can.
The vaccine supply chain is fragile. There are going to be a lot of stresses in the health care system in the coming years. Lots of vaccines may become hard to get and they may be prioritized for the young.
When I joined the Navy they vaccinated me for over 15 different things one week. I update and renew my vaccinations every five years. I just got my Shingles vaccination last year.
I am praying that they have a vaccine for Lyme Disease soon. Climate change is allowing an explosion in tick populations.
