Infant mortality rates have seen a significant decrease worldwide since 1974, with rates plummeting by over two-thirds by 2021. This positive trend can be attributed to a combination of factors including lower poverty levels, improved nutrition, cleaner air and water, and the widespread availability of vaccines and treatments.
A recent study conducted by the World Health Organization (WHO) has shed light on the crucial role that vaccines have played in reducing infant mortality rates. According to the study, vaccines have accounted for 40% of the decline in infant deaths, preventing a staggering 154 million deaths over the course of 50 years.
The WHO’s Expanded Programme on Immunization, launched in 1974, has been instrumental in making vaccines more accessible in developing countries, particularly in the Global South. Through vaccination campaigns led by the WHO and organizations like Gavi, vaccine coverage in these regions has significantly increased, resulting in major improvements in child health.
Among all the vaccines, the measles vaccine has had the most profound impact, averting a remarkable 93.7 million deaths since 1974. Researchers utilized data on vaccine coverage, mortality rates, and disease spread models to analyze the impact of vaccines over the past five decades, showcasing the undeniable benefits of vaccination on global health.
Despite these successes, there are growing concerns about declining vaccination rates, especially for diseases like measles, mumps, and rubella. The study underscores the critical importance of vaccines in promoting global health and emphasizes the ongoing need for the development and distribution of vaccines for other diseases.
The positive impact of vaccines on mortality rates and overall health is undeniable, as vaccines continue to save lives and prevent unnecessary suffering across the globe. The study serves as a reminder of the significant contribution of vaccines to global health and the importance of continued efforts to ensure widespread vaccination coverage for all.
