CEP: Editorial - More Than a Spoonful of Sugar

March
2013
Editorial
Cynthia Mascone
Many of us remember receiving our polio vaccine on a sugar cube. Indeed, that was the motivation behind A Spoonful of Sugar, a song from the classic Disney movie Mary Poppins. Walt Disney had instructed the Sherman brothers, Robert and Richard, to come up with a catchy song for the film. When Robert arrived at home, after working all day trying to come up with an idea, his wife told him that the children had gotten their polio vaccine that day. Thinking they had gotten a shot, he asked them if it hurt. His son answered that the medicine was put on a cube of sugar and he swallowed it. And so “a spoonful of sugar helps the medicine go down was born.
