Salk

Hooray for Dr. Jonas Salk, creator the polio vaccine! He refused to patent it so it would be freely available to all who might need it and is responsible for the almost non-existence of the disease today.

That's Google's banner for today in honor of the good doctor's 100th birthday. His vaccine has saved countless lives and prevented a great deal of suffering. So shut up and VACCINATE YOUR DAMN KIDS! Crazy anti-vaxxers put us all at risk in defiance of science. It pleases me to see good sense prevail so publicly like this.
