Silver nitrate was used as a medical treatment for thousands of years. But in 1999, the FDA ruled that it was unsafe. Candace investigates how and why modern day antibiotics took over the use of silver nitrate as a treatment for babies with eye infections born to mothers with gonorrhea. She also questions why so many parents allow their children to be given Erythromycin as a treatment when they don't need it.

Since the 1970s there's been an increase in SIDS or Sudden Infant Death Syndrome. Is there a link between this and diphtheria, tetanus, and acellular pertussis (DTAP) vaccines? Candace starts by looking at the tetanus part of this vaccine combination, and examines the data that led her to question why infants are required to take it.
