Don't bet on this one. Despite relatively high vaccination rates in the U.S., many American communities still have outbreaks of diseases like measles and pertussis, a respiratory illness characterized by spasms of coughing that can last for weeks or even months. In 2003, 13 children died of the infection. Unvaccinated children can also spread infection to vulnerable family members, such as an infant sibling or an elderly grandparent living at home.
