Antibody Response of Low Birth Weight Infants to <i>Haemophilus influenzae</i> Type b Polyribosylribitol Phosphate-Outer Membrane Protein Conjugate Vaccine

Abstract

We conclude that LBW infants, and especially those born at 27 or less weeks' gestation, do not respond as effectively to the HIB vaccine. We speculate that reevaluation of the current immunization schedule may be required for very LBW infants.
