> Come on. If humanity were unable to survive without the help of artificial vaccines, we would never be here.
I never said that humanity couldn't survive without a vaccine. Clearly we can. We also can survive with rotten meat and with poor shelter and with rampant war and famine. Sure a larger portion of us would die, but humanity would certainly survive.
Anyway my point was that when you're infected with a virus, your body basically builds up the ability to recognize certain proteins that the virus expresses and uses that to fight it off. It takes time to build up the ability to fight it off. The vaccine exposes you to basically the same proteins so that your body is able to identify and fight off the virus more quickly after infection. So really the vaccines are just priming your immune system so that it can better do its job.
