Actually President Roosevelt wasn't in his wheelchair all the time, he would often times walk into a room to show he didn't have time for weakness. The cost of todays vaccines far outweigh the benefits and seem to be used more as a revenue generator than anything else.
Vaccines should not be required for many reasons. The first reason is the vaccine can cause serious, if not deadly, side effects. these side effects include anaphylaxis, which is an allergic reaction to the vaccine. i have in fact had anaphylaxis to the tetanus shot and it is far from a party. Another very valid reason vaccines should not be required is that in several instances these "horrible" diseases that vaccines target are almost 100% harmless.
