An outbreak of measles in Clark County, Washington, has provided more fuel to an ongoing national debate about the role of vaccinations and the freedoms from immunization requirements.

More than 40 cases have been confirmed in Washington, and the state's governor, Jay Inslee, has declared a state of emergency. So far this year, measles cases have been confirmed in 10 states across the country.

This week, Frederick Uncut producer Wyatt Massey spoke with Kurt Seetoo of the Maryland Department of Health Center for Immunization to learn more about the importance of vaccines. The center oversees various immunization and vaccination programs in the state, such as the Vaccines for Children Program.

Plus, producer Graham Cullen takes a field trip with a recorder in hand to gather audio of a vaccine being administered- to himself.
