Expert Report Effect of DTP Vaccines on Mortality in Children in Low-Income Countries

... VII. Final Remarks and Conclusions
[...] We base our decisions on the best available evidence, and this evidence tells us that it is likely that the DTP vaccine increases total mortality in low-income countries. I therefore believe no one should be offered this vaccine without full informed consent that includes information that the vaccine is likely to increase total mortality.
I also believe that the vaccine should not be recommended and that, if anyone wants to use it, it must be as part of a large randomized trial. I consider the need for randomized trials an urgent ethical imperative.

Aaby and colleagues have pointed out that the WHO uses the DTP vaccine as a marker for good coverage of vaccination in general (3). The WHO has operated with reaching a “milestone of 90% national coverage with 3 doses of diphtheria-tetanus-pertussis vaccine (DTP3) in all countries by 2015” (9). This should not happen. Program performance indicators should be those which are known to be positively associated with better child survival (3).
