A new study in The Lancet shows vaccinations saved 150 million children in the last 50 years.
Measles vaccination alone saved 60% of these lives.
Large-scale immunization programs led to this significant decline in vaccine-preventable diseases.
Measles vaccination rates rose globally from <20% (2000) to 70% (2021).
Similar increase observed for DTP3 (diphtheria, tetanus, pertussis) vaccinations.
Vaccinations are estimated to contribute to 40% of the decline in infant mortality rates (10% in 1974 to 3% in 2024).
Global Vaccination Coverage:
Measles vaccinations:
Highest impact - 94 million lives saved.
Western Pacific region: Most dramatic increase (2% in 2000 to 91% in 2021).
Southeast Asia: Significant progress (15% in 2010 to nearly 80% in 2021)
DTP3 vaccinations:
Over 80% of infants received all 3 doses globally in 2021
Western Pacific region again leads (less than 10% in 1980 to 90% in 2021) .
Historical Perspective:
50 years ago, vaccination coverage was minimal outside of Europe and North America.
World Health Assembly formed the Essential Programme on Immunization in 1974, leading to a rise in vaccination rates.
Gavi, the Vaccine Alliance, was formed in 2000 to address vaccination gaps in developing countries.
Challenges and the Way Forward:
Millions still die from preventable diseases due to insufficient vaccination coverage
Universal vaccine coverage is crucial.
This requires:
Increased government investment in immunization programs.
Addressing vaccine hesitancy and misinformation.
Conclusion:
Vaccinations are a powerful tool in saving lives and reducing child mortality.
Continued efforts are needed to achieve universal vaccination coverage and protect children worldwide.
