Your teen goes to the pool for a fun day out. A week later they have a little summer flu. You don’t think much of it until they text you from bed saying they can’t stand up. Within days they are paralyzed, on a breathing machine. A decade later you are changing their diapers while they sit in bed on a ventilator.
That’s polio folks. It’s only been gone in the US for a few decades, and only because of a vaccine. RFK and Trump want to ban that vaccine and bring back paralyzed kids.
