Health, you are so right. We are given brains to think for ourselves.
Who would refuse a PROVEN vaccine for cancer or heart disease?
At the least, the flu will take you out of commission and make you utterly MISERABLE for at least a week.
These vaccines are gifts from heaven above. If your ancestors, 200 years ago, who had an extremely high probability of dying of an infectious disease, were offered any of these vaccines, you could see that they would be fools not to take it.
Most infectious diseases are gone BECAUSE of vaccines – also, better sanitation, public health, public education, virology and medicine, but vaccines definitely played a part in that.
Chances are that none of us will die of infectious diseases, unlike the prospect for our ancestors.
