Please note, there was no vaccine for scarlet fever, bubonic plague, and very little vaccination for typhoid fever, and yet they all subsided at the same rate as those for which there was widespread vaccination. These declines occurred BEFORE mass vaccination. There were many other factors. Better sewage disposal, refrigeration, antibiotics, more sanitary work and living conditions.

And if you think that a philosophical exemption to vaccines is a bad idea because the polio vaccine wiped out polio, please think again:
          The Salk vaccine was tested by the Poliomyelitis Vaccine Evaluation Center of the University of Michigan  (Francis et al. 1955) on 1,000,000 children. 749,236 children were used as placebo.
          After only six months of observation, 67.5/100,000 of the vaccinated children had caught polio. 62.3/100,000 of the placebo group caught polio. Based upon this study the vaccine was released on the public.

          The USA had a 95+% polio vaccination rate. Yet Germany and Finland, both of which had a substantially lower polio vaccination rate saw reduction of polio cases to the same degree and over the same period as the US.

          Aside from serious questions as to their efficacy, there have been millions of people adversely effected by vaccines, from causing the disease the vaccine was meant to prevent, to limb paralysis, meningitis, death (SIDS), arthritis, autoimmune disorders, HIV infection from the SV40 derived from the infected monkey kidney tissue through which some polio vaccines were filtered, mercury and aluminum toxicity. And it is thought that only 1 in 10 adverse effects are actually reported.
