A new study has found that aid channeled into vaccination has had a significant effect on improving childhood vaccination rates in the poorest countries.
Researchers at the Harvard School of Public Health, writing in the current edition of The Lancet (pdf), have analyzed how funding provided by aid donors through the Global Alliance for Vaccines and Immunization has raised the percentage of children receiving the combined diphtheria, tetanus and pertussis vaccine between 1995 and 2004.
This independent assessment of the effect of GAVI on DTP3 coverage shows that GAVI has contributed to increased DTP3 coverage in countries with baseline DTP3 coverage of 65% or less at their first approval for GAVI funding. We estimate the cost to GAVI to be about $8·40–20 per additional child immunised. This estimate is close to the proposed cost to GAVI of $20 per additional immunised child.
Once again, immunization has been shown to be one of the most cost-effective interventions in development.
