ELI5: Explain Like I'm 5

Raisins (South Park)

In an episode of a TV show called South Park, one of the characters named Kyle, finds out that his baby brother is going to turn into a giant raisin because his mom (Kyle's mom) doesn't vaccinate the baby. This is because in the show, the vaccines turn children into raisins instead of protecting them from diseases.

So, Kyle and his friends set out to find a cure for his baby brother and stop other kids from turning into raisins. They discover that the cure is to give the kids who were turned into raisins a special kind of injection to reverse the effects of the vaccine.

In the end, they are successful in curing Kyle's baby brother and all the other kids who were turned into raisins. But, the episode is actually a satire on the anti-vaccine movement, which encourages people not to vaccinate their children based on false information, putting their health and the health of others at risk.
