Through research, a vaccine was developed. Most people of my generation were vaccinated as children. Today, small pox has been virtually eradicated from the earth. Now, no one needs to be vaccinated. My children will never have the disease that once threatened my grandmother's life.
Research is the key.
It is the brightest hope there is in the fight against the terrible maladies that afflict mankind. It is the key to increasing the quality of life for us all.
