And don't take any malaria shots when you go to Africa. Its full of (gasp) chemicals!
And those Diptheria, Menningitis, Polio and Tetanus shots they give you? Avoid them like the Plague! They are full of chemicals too!
If you're not very young or not very old, otherwise healthy and don't come in regular contact with those who are at high risk of dying due to an infection like flu, then by all means L-188 don't feel as though you need to take flu shots. But don't discourage others that meet this criteria.
Oh...and don't drink wine or beer. They have chemicals in them too!
