The CDC notes that when a measles outbreak occurs, the cost to taxpayers can be substantial. Public health responsibilities include "identification of cases, isolation of patients and vaccination, administration of [[immune globulin]], and voluntary quarantine of contacts who have no evidence of measles immunity...In Iowa, the public health response to one imported measles case cost approximately $150,000."<ref>Centers for Disease Control and Prevention, Morbidity and Mortality Weekly Report, ''Outbreak of Measles --- San Diego, California, January--February 2008'', February 29, 2008 [http://www.cdc.gov/mmwr/preview/mmwrhtml/mm5708a3.htm]</ref>

Other diseases besides the measles have also started not only to reappear but also to kill children. Hib (''[[Haemophilus influenzae]]'' type B) meningitis recently killed an infant in Minnesota. The child who died had not been vaccinated. Two others who had been either partially, but not fully, vaccinated, or who had an immune deficiency were seriously sickened. The vaccine for Hib is less than twenty years old, but this is the first death due to the disease in the state of Minnesota since the vaccine was introduced.<ref>[http://children.webmd.com/vaccines/news/20090123/hib-outbreak-kills-unvaccinated-child Hib Outbreak Kills Unvaccinated Child]</ref>
