The reason I ask is because our bodies as human beings have an amazing immune system and unless you have an autoimmune disease, naturally our bodies can heal ourselves from sickness.
I’m speaking primarily on the common cold, Influenza or anything similar like it, including even COVID.
Our immune system is amazing? Yes, it is! Wiil it protect us against every pathogen in existence? No! Can vaccines help? Yes. Source: History.
History proves we existed for over 97% of our existence without VAX and survived fine
But did they survive fine?
Should stop washing your hands or showering regularly if that’s how you decide whether something is important.
That has to deal with hygiene, not vaccination, or even natural immunity.
You’re talking about surviving without X. Well, we survived without washing our hands, showering, brushing our teeth, etc. for 99% of human existence as well. Better be consistent in your beliefs and return to living as a hunter-gatherer in the woods.
Humanity was regularly decimated by diseases we had no defences for across our entire history. It was a major factor the fall of several major empires. Just because it didn’t annihilate the entire species doesn’t mean we “survived fine”.
