Recently, there have been several outbreaks of vaccine-preventable diseases across the United States. For example, this year, a measles outbreak in New York infected more than 180 people. In Washington state, a similar measles outbreak has sickened 74 people
so far and has spread to other states. In Oregon, a child who did not receive his recommended tetanus vaccination spent two months in intensive care. Americans are once again suffering from diseases that vaccine use had mostly eliminated, including whooping
cough and tetanus.
