Vacccines are not useless. Think of infectious disease like a massive cold front approaching. If the front is strong (no vaccination), then the drop in temperature over time when the front arrives is great. If the front can be weakened (by introducing a weaker version of the infectious agent), the pressure gradient is relieved and the drop in temperature (virulence of the infection) is reduced.
I'm just saying i believe the classical reasoning for vaccination. Do I believe that all current vaccines are needed or are what they tell us they are? Hell no.
Hey worthless maggot, I listened to my grandpa tell about how he lost two siblings on the farm including his twin brother to things like measles and smallpox because vaccination was not what it is today, or my dad who remembers seeing those stricken by polio when he was a young child. I'm not saying we aren't lied to today about some vaccines but I do believe in the general concept.
