Return of disease threatens the health of those who remain unimmunized by choice as well as those who are immunized appropriately but experience loss of vaccine-induced immunity. The solution to continued threats of illness caused by these untreatable but readily preventable diseases is compliance with recommendations for administration of the measles-mumps-rubella vaccine. Here we examine trends in the epidemiology of measles, mumps, and rubella in recent years and consider the consequences of loss of protective immunity within our country.<\/jats:p>","DOI":"10.1542\/peds.2020-0251","type":"journal-article","created":{"date-parts":[[2020,7,27]],"date-time":"2020-07-27T08:29:52Z","timestamp":1595838592000},"source":"Crossref","is-referenced-by-count":11,"title":["The Importance of MMR Immunization in the United States"],"prefix":"10.1542","volume":"146","author":[{"given":"Olivia","family":"Perrone","sequence":"first","affiliation":[{"name":"Department of Pediatrics, School of Medicine, Tufts University and Tufts Medical Center, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H.
