Conclusion
As vaccines became mandatory, the number of cases fell dramatically and some diseases were eradicated. However, the more successful vaccines were at eradicating diseases, the more controversial they became, because people did not want to take risks to prevent seemingly nonexistent illnesses. Also, some parents refused vaccines due to religious and philosophical objections. They sought exemptions, and when exemptions were not available, they went to court. Mandatory vaccine policies persist because courts and public health organizations have generally concluded that the responsibility to protect the community outweighs individual rights.
