Abstract
Incidence of childhood leukaemia was
studied among subjects of a vaccine trial in
Finland comparing the polysaccharide-diptheria toxoid
conjugate and oligosaccharide-CRM197 conjugate
Haemophilus influenzae type b conjugate
vaccine formulations. Eighty cases of
childhood leukaemia were detected: 35 among
children on the polysaccharide-diptheria toxoid
conjugate arm, and 45 among children on the
oligosaccharide-CRM197
conjugate arm, which was not statistically
significant.
