In a groundbreaking new study, the World Health Organization (WHO) has estimated that vaccines have played a major role in preventing infant mortality worldwide since 1974. The study, which involved 21 authors and combined three types of data and research results, found that vaccines have saved an estimated 146 million lives among children under 5 in the past 50 years.
According to the study, vaccines accounted for 40 percent of the decline in infant mortality globally since 1974. The measles vaccine alone was found to have averted 93.7 million deaths. Overall, vaccines have prevented 154 million deaths over the past five decades.
The success of vaccination campaigns led by WHO and Gavi, the Vaccine Alliance, has drastically increased vaccine coverage in the Global South over the years. Researchers used data on actual mortality rates, vaccine coverage, and disease spread to track the benefits of vaccines, highlighting their crucial role in public health.
Despite the recent success of Covid-19 vaccines, there has been a concerning decrease in support for childhood vaccinations. While vaccination rates have increased in recent years, it is important to remember the impact vaccines have had in saving lives and preventing suffering.
Vaccines have given people 9 billion additional years to live their lives, emphasizing their importance in public health. As we continue to navigate the challenges of the Covid-19 pandemic, it is crucial to remember the life-saving benefits of vaccines and to support childhood vaccination efforts around the world.
