The introduction of DTP and OPV among children in urban Guinea-Bissau
Among 3–5-month-old children, having received DTP (± OPV) was associated with a mortality hazard ratio (HR) of 5.00 (95% CI 1.53–16.3) compared with not-yet-DTP-vaccinated children.
Vaccination timing was set by birthday relative to quarterly weighing sessions. Infants aged three to five months who had received DTP died at five times the rate of not-yet-vaccinated infants (HR 5.00, 95% CI 1.53–16.3), based on 11 and 5 deaths.
