Incorrect Dates: In the Original Contribution entitled “Serum Vaccine Antibody Concentrations in Children Exposed to Perfluorinated Compounds,” published in the January 25, 2012, issue of JAMA (2012;307:391-397), inclusion dates were incorrectly reported in the Abstract and text. In the Abstract, the second sentence of the Design, Setting, and Participants section should have read, “A total of 656 consecutive singleton births were recruited during 1997-2000, and 587 participated in follow-up through 2008.” In the text, the first sentence of the Methods section should have read, “The birth cohort was formed from 656 consecutive singleton births at the National Hospital in Tórshavn, Faroe Islands, during 1997-2000.” This article was corrected online.
