===Loss of Herd Immunity in the United States===

In February of 2008, an outbreak of [[measles]] occurred in [[San Diego]].  This outbreak was a result of the loss of herd immunity.  Due to the relaxed statutes in [[California]], many children in the San Diego community went unvaccinated.  One of these children, a boy, was able to contract measles in Sweden, return to the United States and cause the outbreak.  During this time, dozens of children contracted the disease and many were hospitalized with fevers reaching 104<math>^\circ</math>.  These hospitalizations included a 3 month old baby who nearly died of dehydration.  The parents of the unvaccinated boy were unapologetic for nearly killing the other children, instead feeling their fears of vaccines were sufficient reason to endanger the lives of many.  The fear of the [[MMR]] vaccine (a vaccine against [[measles]], [[mumps]] and [[rubella]]), which no longer has mercury in it, continues to this day, with the vaccine being wrongly accused of causing [[autism]].<ref> [http://www.cdc.gov/mmwr/preview/mmwrhtml/mm5708a3.htm]</ref>
