SUMMARY
This study’s objective was to assess whether the sequence of diphtheria-tetanus-pertussis vaccine (DTP) and measles vaccine (MV) was associated with child survival. Using a data set previously used to assess non-specific effects of vaccines with no consideration of vaccination sequence researchers found that out-of-sequence vaccinations in children were associated with higher mortality compared with children vaccinated in-sequence.
