In the article entitled "Comparison of the Safety and Immunogenicity of Acellular (BIKEN) and Whole-Cell Pertussis Vaccines in 15- to 20-Month-Old Children" published in the March issue (1993;147:290-294), the second sentence in paragraph four of the "Results" section should have read as follows: "There were differences in the rates of certain adverse reactions to WC-DTP vaccine between racial groups (reactions in whites > Hispanics > blacks), and one mostly white group had higher rates of several local and systemic reactions to both vaccines than a mostly black group." We regret the error.
