Anti-vaxxers really do know **** all. For a start there is vastly more Formaldehyde in an apple than in vaccines.Your body even produces it's own, again in much larger amounts than vaccines.
And Mercury comes in two forms. The one used in vaccines is easily expelled from your body, and if you believe small amounts of mercury are bad for you than i guess your already fucked considering a small portion of fish such as tuna or mackerel contains more Mercury than a vaccines. Ever had Mercuricrome put on a cut? Stuffs full of mercury.
Ever had a drink of milk or eaten any dairy products (among a whole host of other foods which having one meal of contain more aluminium than one vaccine) ? Again, it's a wonder any of us are still kicking or not brain damaged.
Anti-vaxxer bullshit is tiresome. But those who believe are almost impossible to sway even when presented with facts and modern scientific research, so I won't bother.
