Number needed to vaccinate to prevent hospitalizations of pregnant women due to inter-pandemic influenza in Sweden, 2003-2009.

Background: The evidence of increased risk of severe disease for healthy pregnant women due to inter-pandemic influenza consists mainly of observational studies of health service utilization in USA and Canada. However, these results can be context dependent and estimates in a European setting are sparse. For policy purposes we therefore decided to elucidate the potential value of vaccination in Sweden.

Breastfeeding status as a predictor of mortality among refugee children in an emergency situation in Guinea-Bissau.

Objective: To identify the population risk factors in emergency situations, we studied breastfeeding status as a predictor for child mortality during a war in Guinea-Bissau.

Methods: Data on breastfeeding status are routinely collected by the surveillance system of the Bandim Health Project in Bissau. We used data collected during a 3-month period prior to the war in Guinea-Bissau in June 1998 to assess the impact of breastfeeding status on mortality in an emergency.
