I remember polio...I had childhood friends who contracted the disease prior to the vaccine.. I saw the broken body ...the results of the disease. We stood in line in the school gym and got the polio vaccine. We were protected from the horrid ravages of the disease.
I had a case of severe measles that could have killed me as a kid if I weren't tough enough. That was before the measles vaccine.
Take the damn shot and shut up. The shot cannot give you one hundredth of the negative consequences the illness might cause. And have a little respect for your fellowman and their well-being.
