The Analysis of Non-communicable Diseases Prevention Policies in Africa (ANPPA) project is a multi-country study that aims at promoting Multi-Sectoral Approach (MSA) to policy-making for NCD (Non-communicable Diseases) prevention by...read more
This is a four-year multisite research project being implemented in 6 Health and Demographic Surveillance Systems (HDSS) sites within the INDEPTH network; building on previous vaccine studies done in Guinea Bissau, West Africa.
The studies have consistently shown that the main childhood interventions with vaccines and micronutrients used by the international health community have the so-called non-specific effects (NSE), i.e. effects which are not explained by the prevention of the targeted infection or deficiency. These effects are often sex-differential.
WHO recommends schedules for delivery of vaccines and micronutrients which are often not followed. Many children receive vaccines out-of-sequence; e.g. BCG simultaneously with diphtheria-tetanus-pertussis vaccine (DTP), DTP with measles vaccine (MV), or DTP after MV. Such variations have very different NSE on overall mortality though it has not yet been recognized
The project aims to set up systems to monitor and assess the impact of vaccinations and other interventions for both boys and girls in the Nairobi HDSS. The project will also determine the risk factors for delay in uptake of childhood interventions with emphasis on possible differences between boys and girls. The project will also examine the causes of out-of-sequence vaccinations.
