Evidence of Increase in Mortality After the Introduction of Diphtheria–Tetanus–Pertussis Vaccine to Children Aged 6–35 Months in Guinea-Bissau: A Time for Reflection?
"Bandim Health Project (BHP) has followed an urban community in the capital of Guinea-Bissau with a demographic surveillance system since December 1978. The national immunization program in Guinea-Bissau started in 1986 with funding from UNICEF. From January 1980, BHP conducted tri-monthly weighing sessions of all children in the community to identify malnourished children. From June 1981, vaccinations were offered in connection with these weighing sessions."
"When the project started in 1978, child mortality was very high. Malnutrition was assumed to be the main cause and a study was, therefore, initiated to determine why children were malnourished (6–8)."
Eligible for vaccination were children "between 3 months and 3 years of the age. However, some children in this age group were not vaccinated. Both nurses and mothers thought that sick or otherwise weak children should not be vaccinated."
"Although having better nutritional status and being protected against three infections, 6–35 months old DTP-vaccinated children tended to have higher mortality than DTP-unvaccinated children. "
"Although lower mortality was expected for DTP-vaccinated children compared with the frail unvaccinated children, DTP vaccination was associated with higher mortality, particularly in girls."
