The idea that our forefathers lived longer because they didn't use vaccines is a huge LIE and a weak argument.
You see one old man who is 90 and you think everyone was like him. But you forget the five other children in his compound who died before their fifth birthday because of measles, smallpox, or "juju" that was actually just an infection. Eg;ogbanje
In 1990, out of every 1,000 children born in Nigeria, 193 of them died. Today, that number has dropped to about 52. It means less kids are dying now because of the wins of "science"
That "olden days" you are praising was actually a time of great sorrow for many parents who buried their children in the backyard. The reason we are doing better today isn't because of "vibes" or WhatsApp broadcasts. It is because of vaccines and better medicine.
Our ancestors didn't have a "secret" for long life; they were just lucky to survive a world where a simple cough could kill a baby. If you want to go back to that way of life because of some story you read on the internet. Fine. But it is like throwing your children into a fire because you heard it makes them stronger.
Antivaxxers are dangerous people to all of us. Their stories are killing innocent kids.
