In “Response of Infants to Haemophilus influenzae Type b Polysaccharide and Diphtheria-Tetanus-Pertussis Vaccines in Combination” by Martha L. Lepow et al. (June 1984), an error appeared in table 4, page 955. The number in the last column of the first line should be 0.20, not 0.04. The text is correct.
