During a portion of an interview with NBC News aired on Thursday's edition of "NBC Nightly News," Chicago Department Of Public Health Commissioner Dr. Olusimbo "Simbo" Ige responded to a question on whether the measles outbreak in the city where most of the cases were traced back to a city migrant shelter is under control by stating that "we are trying to get it under control by vaccinating as many people as possible." Ige also noted that vaccination does take time.
