BCG coverage and delays in BCG vaccination in Guinea-Bissau

9 December 2014

BCG vaccination is recommended at birth in low-income countries, but vaccination is often delayed. Often 20-dose vials of BCG are not opened unless at least ten children are present for vaccination (“restricted vial-opening policy”). BCG coverage is usually reported as 12-month coverage, not disclosing the delay in vaccination. Several studies show that BCG at birth lowers neonatal mortality. We assessed BCG coverage at different ages and explored reasons for delay in BCG vaccination in rural Guinea-Bissau.

Newborn twins are a vulnerable group in Guinea-Bissau and elsewhere in Africa

9 December 2014

Yet, few studies have examined what happens after hospital discharge. In Guinea-Bissau we found that the post-perinatal infant mortality rate of twins was double that of singletons. No excess in twin hospitalisations was observed, possibly implying obstacles to hospital admission for twins in case of severe illness.

Vitamin A with vaccines after 6 months does not improve survival

9 December 2014

WHO recommends utilizing vaccination contacts to deliver high-dose vitamin A supplementation to children aged 6-59 months. The effect of this policy on overall child mortality has not been assessed. We found no overall benefit of this policy in a randomised trial in Guinea-Bissau, but a strong sex-differential effect; vitamin A was beneficial for gorls, bur associated with increased mortality for boys.
