This pattern reflects a growing number of parents who worry that vaccines are unsafe, ineffective, or unnecessary. These increases are troubling, especially in the face of recent outbreaks of childhood diseases such as measles and pertussis (whooping cough)—diseases that used to cause widespread illness and even death in the United States, until they were all but eliminated by successful immunization programs. Now those diseases are back: there have been 593 cases of measles to date this year in the U.S. Compare that to only 119 cases per year on average in 2009-2013.
