The California Department of Health said it “strongly recommends against the intentional exposure of children to measles. It unnecessarily places the exposed children at potentially grave risk and could contribute to further spread.” No known “measles parties” have been thrown to date, but the expression started cropping up in local media reports after a San Francisco radio station reported that a local mother had [offered](http://blogs.kqed.org/stateofhealth/2015/02/06/health-officials-discourage-measles-parties/) to arrange a play date between sick and healthy children. Officials have [confirmed](http://www.cdph.ca.gov/Pages/NR15-008.aspx) 59 cases of the measles across the state, 42 of which have spread through Disney theme parks. ## Transcript This vaccine is highly effective and very safe and so the best way to protect your child is to get your child vaccinated we recommend two doses one between 12 and 15 months and the second between the ages of four and six that's the best way to make sure your children are safe and healthy and protected against the measles virus. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/3703002/measles-parties-california/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/3703002/measles-parties-california/"},"headline":"Rumored 'Measles Parties' Elicit a Warning in California","datePublished":"2015-02-10T16:05:01.000Z","dateModified":"2026-08-04T07:59:57.079Z","description":"Health department “strongly recommends against the intentional exposure of children to measles\"","url":"https://time.com/3703002/measles-parties-california/","keywords":["Infectious Disease"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blted331bac38e33c15/69877e68428a9e7fc9cc70de/measles2.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Dan Kedmey","jobTitle":null,"url":"https://time.com/author/dan-kedmey/"}],"articleSection":"Health","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blted331bac38e33c15/69877e68428a9e7fc9cc70de/measles2.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"Measles Outbreaks Spread In U.S.","caption":"Measles Outbreaks Spread In U.S.","creditText":"CDC/Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/health/","name":"Health"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/infectious-disease/","name":"Infectious Disease"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/3703002/measles-parties-california/","name":"Rumored 'Measles Parties' Elicit a Warning in California"}}]},{"@context":"https://schema.org","@type":"VideoObject","name":"CDC Urges Parents To Vaccinate Children Against Measles","description":"CDC Urges Parents To Vaccinate Children Against Measles","thumbnailUrl":"https://cdn.jwplayer.com/v2/media/JJyuqpll/poster.jpg?width=720","uploadDate":"2015-01-31T18:39:54.000Z","contentUrl":"https://cdn.jwplayer.com/manifests/JJyuqpll.m3u8","embedUrl":"https://time.com/3703002/measles-parties-california/","duration":"PT19S","potentialAction":{"@type":"SeekToAction","target":"https://time.com/3703002/measles-parties-california/?jw_start={seek_to_second_number}","startOffset-input":"required name=seek_to_second_number"}}] ```
