Dr. Peter Aaby is renowned for studying and promoting vaccines in Africa with over 300 published studies. In 2017, he published a study finding children vaccinated with DTP were 10 times more likely to die in the first 6 months of life than the unvaccinated. Dr. Aaby’s study therefore concluded that:
“All currently available evidence suggests that DTP vaccine may kill more children from other causes than it saves from diphtheria, tetanus or pertussis.” More disturbing is that children vaccinated with DTP were dying from causes never associated with this vaccine, such as respiratory infections, diarrhea, and malaria. This indicated that while DTP reduced the incidence of diphtheria, tetanus, and pertussis, it increased susceptibility to other infections.
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?
Abstract
Whole-cell diphtheria–tetanus–pertussis (DTP) and oral polio vaccine (OPV) were introduced to children in Guinea-Bissau in 1981. We previously reported that DTP in the target age group from 3 to 5 months of age was associated with higher overall mortality. DTP and OPV were also given to older children and in this study we tested the effect on mortality in children aged 6–35 months.
Conclusion
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. All studies of the introduction of DTP have found increased overall mortality.

Key Observations
• DTP and oral polio vaccine (OPV) were first introduced to children aged 6–35 months in June 1981 in an urban area in Guinea-Bissau. Children who were DTP-vaccinated at the first weighing session after the introduction of DTP had significantly better weight-for-age z-scores than those not vaccinated.
• Although better survival was expected, the DTP-vaccinated children had twofold higher mortality than DTP-unvaccinated children.
• In a meta-analysis of the three studies of the introduction of DTP in urban and rural Guinea-Bissau, DTP-vaccinated children had twofold higher mortality than DTP-unvaccinated children.

Peter Aaby (Danish, born 1944 in Lund, Sweden) is trained as an anthropologist but also holds a doctoral degree in medicine.[1] In 1978, Peter Aaby established the Bandim Health Project, a Health and Demographic Surveillance System site in Guinea-Bissau in West Africa, which he has run ever since.[2] In 2000, Peter Aaby was awarded the Novo Nordisk Prize, the most important Danish award within health research.
Aaby is credited for the discovery of non-specific effects of vaccines – i.e. effects of vaccines, which go beyond the specific protective effects against the targeted diseases.[3] The theory of non-specific effects of vaccines was established in 1991 and later documented in several trials on measles vaccine, BCG, oral polio vaccine, DTP vaccine and smallpox vaccine.
