The Measles Vaccine Has Had the Most Significant Impact on Lives Saved

Global immunisation efforts over the past 50 years have been credited with saving at least 154 million lives, with infants accounting for the majority of those saved. Among the various vaccines administered, the measles vaccine has demonstrated the most substantial impact, being responsible for 60% of all lives saved through immunisation programmes.
Measles Vaccine's Dominant Contribution

The measles vaccine alone accounts for a remarkable 60% of the lives saved due to immunisation over the last five decades. This highlights its crucial role in global health initiatives, particularly in preventing mortality among children, as measles primarily affects the young. The effectiveness of this single vaccine underscores the profound benefits derived from widespread vaccination campaigns.
Broader Impact of Immunisation Efforts

Collectively, vaccines against 14 different diseases, as part of the Expanded Programme on Immunisation (EPI), have significantly reduced infant deaths by 40% over the past 50 years. In Africa, this reduction in infant mortality has been even more pronounced, exceeding 50%. These figures indicate a substantial improvement in child survival rates globally, allowing more individuals to reach adulthood.
Polio Vaccine's Impact on Mobility

Beyond direct life-saving, the polio vaccine has had a transformative effect on the quality of life for millions. It is estimated that over 20 million people are currently able to walk today who would have otherwise faced paralysis due to polio. This demonstrates how immunisation contributes not only to survival but also to preventing lifelong disabilities.
Long-Term Health Benefits of Vaccination

The positive impact of vaccines extends far beyond immediate survival. The data indicates that when a vaccine successfully saves a child's life, that individual can expect to live an average of 66 years of full health. Cumulatively, this has resulted in the gain of 10.2 billion years of full health across the global population over the past five decades, underscoring the extensive long-term value of immunisation.
