Vaccines are among the most powerful and cost-effective inventions in history, making once-feared diseases preventable. Global immunization efforts have saved at least 154 million lives over the past 50 years, according to a study published in The Lancet. This is equivalent to six lives saved every minute of every year. Vaccines have cut infant mortality by 40% globally and by more than 50% in Africa. In addition to preventing early deaths, the study found that for every life saved through immunizations, a further 66 years of full health are gained.

Vaccines have saved at least 154 million lives over the past 50 years
Vaccines are among the most powerful and impactful inventions in human history, making once-feared diseases preventable. Vaccines have saved at least 154 million lives over the past 50 years, according to a study published in The Lancet. This number is only expected to increase, with new vaccine introductions for diseases such as malaria, COVID-19, respiratory syncytial virus (RSV), meningitis, cholera, and Ebola.
The study, led by the World Health Organization (WHO), analysed the global and regional health impacts of the Expanded Programme on Immunization (EPI), which aimed to ensure equitable access to life-saving vaccines for all children, regardless of their socioeconomic status or location. The EPI has been so successful that it has saved an average of six lives every minute since its inception, totalling 10.2 billion full health years gained over the five decades.
Vaccines have been particularly effective in reducing infant mortality, with 95% of the lives saved being children under the age of 5. The measles vaccination alone has saved nearly 94 million lives over the past 50 years and has been responsible for 60% of the lives saved due to immunization. Vaccination against 14 diseases, including diphtheria, hepatitis B, measles, polio, and tetanus, has directly contributed to reducing infant deaths by 40% globally and by more than 50% in Africa.
In addition to saving lives, vaccines have played a crucial role in advancing health equity and improving overall health and quality of life. They have prevented the long-term problems that many diseases cause, such as disability, hearing loss, seizures, and cognitive difficulties. The HPV vaccine, for example, can prevent up to 90% of HPV-related cancers, including nearly all cases of cervical cancer.
Despite the overwhelming success of vaccines, public health specialists worry that misinformation and funding cuts could affect vaccination rates and potentially reverse decades of progress. It is crucial to continue investing in immunization programmes and advocating for vaccine uptake to ensure that every person has the chance to live a healthy life.

Measles vaccine has saved 60% of lives
Vaccines are among the most powerful and impactful inventions in history, making once-feared diseases preventable. Global immunization efforts have saved at least 154 million lives over the past 50 years, or six lives every minute. This figure is expected to grow, with new vaccine introductions for diseases such as malaria, COVID-19, respiratory syncytial virus (RSV), and meningitis expected to save millions more lives in the next 50 years.
The measles vaccine has been a significant contributor to reducing infant mortality, accounting for an estimated 60% of the lives saved due to immunization. The impact of the measles vaccine has been substantial, with researchers estimating that 94 million lives have been saved over the past 50 years, or nearly two million measles deaths prevented every year. This makes measles vaccines the most life-saving childhood vaccines currently in use.
Measles is a highly contagious and deadly disease that was once an unavoidable part of childhood, infecting nearly every child and causing millions of deaths annually. The development of the measles vaccine by John Enders and his colleagues in 1954 marked a turning point in the fight against measles. By weakening the virus and triggering immunity without causing the disease, the vaccine has prevented millions of deaths and changed the trajectory of measles infections.
The impact of the measles vaccine has been particularly notable in regions such as Africa and Southeast Asia, where measles was a leading cause of death in children. In Africa, 29 million lives have been saved, while 20 million lives have been saved in Southeast Asia. The measles vaccine has not only prevented deaths but also long-term immune damage and deadly outbreaks, contributing to a healthier and longer life for those who receive it.
Looking forward, continued investment in immunization and global collaboration is crucial to ensuring that every child and person has access to life-saving vaccines. With a cost of less than $1 per child, the measles vaccine is an effective and affordable tool in the fight against infectious diseases.

Vaccines have reduced infant mortality by 40%
Vaccines are among the most powerful and impactful inventions in human history, controlling and preventing diseases, improving health and quality of life, and extending lifespan. Decades of scientific research have shown that the lives that vaccines have saved and the major disabilities they prevent far outweigh the small risk of complications.
Vaccines have saved at least 154 million lives over the past 50 years, according to a 2024 study published in The Lancet. This is a conservative estimate, as the study only covered 14 diseases, and there are now vaccines to protect against more than 30 life-threatening diseases. The number of lives saved is equivalent to six lives every minute of every year.
Vaccines have been particularly effective in reducing infant mortality. Over the past 50 years, vaccination against 14 diseases (diphtheria, Haemophilus influenzae type B, hepatitis B, Japanese encephalitis, measles, meningitis A, pertussis, invasive pneumococcal disease, polio, rotavirus, rubella, tetanus, tuberculosis, and yellow fever) has directly contributed to reducing infant deaths by 40% globally, and by more than 50% in the African Region. The measles vaccine alone has saved nearly 94 million lives over the past 50 years.
Vaccines have also played a crucial role in preventing long-term disabilities and health issues. For example, the human papillomavirus (HPV) vaccine can prevent up to 90% of HPV-related cancers, including almost all cases of cervical cancer. The meningitis A vaccine has nearly eliminated the disease, which previously had a high mortality rate and often caused long-term health issues such as hearing loss, seizures, and cognitive difficulties.

Vaccines have prevented long-term problems and disabilities
Vaccines have been one of the most powerful tools in the history of medicine, preventing long-term problems and disabilities. They have been instrumental in reducing infant mortality, cutting it by 40% globally and by over 50% in Africa. The measles vaccine alone has saved nearly 94 million lives in the last 50 years.
Vaccines have also played a crucial role in preventing long-term disabilities caused by diseases. For instance, the meningitis A vaccine has been highly effective in preventing the severe long-term effects of meningitis, including hearing loss, seizures, limb amputations or weakness, scarring, vision problems, and cognitive difficulties. The success of the meningitis A vaccine has been evident in the "meningitis belt," a region of 26 countries just south of the Sahara desert with historically high rates of meningococcal disease.
Polio is another disease that has been nearly eradicated due to vaccines, and more than 20 million people are able to walk today who would have otherwise been paralysed. Similarly, the HPV vaccine can prevent up to 90% of HPV-related cancers, including almost all cases of cervical cancer. Vaccines have also been effective in reducing the incidence of invasive Hib disease, with a success rate of over 90% in European, Native American, Chilean, and African children in the 1990s.
The impact of vaccines extends beyond individual health. Vaccines have contributed to economic growth by reducing mortality and morbidity, resulting in long-term cost savings. For example, the savings from vaccines were estimated to be in the tens of billions of US dollars globally in 2003.
Furthermore, vaccines have helped maintain herd immunity, protecting not only those who are vaccinated but also those who cannot be vaccinated due to medical exemptions or other reasons. High vaccination rates are crucial in preventing community transmission of highly contagious diseases such as measles.
In summary, vaccines have been a critical tool in preventing long-term problems and disabilities, reducing infant mortality, and improving health equity worldwide. They have saved countless lives, prevented disabilities, and contributed to economic growth.

Vaccines have saved 101 million infants
Vaccines are one of the greatest inventions in history, making once-feared diseases preventable. Vaccines have saved millions of lives, and childhood vaccination has been one of the most impactful and cost-effective measures in controlling and preventing diseases, improving health and quality of life, and extending lifespan.
According to a study published in The Lancet, the Expanded Programme on Immunization (EPI) has saved 154 million lives over the last 50 years, equivalent to six lives saved every minute. Of these, the majority—101 million—were infants. Vaccines have cut infant mortality by 40% globally and by more than 50% in Africa. The study also found that for each life saved through immunization, an average of 66 years of full health were gained, without the long-term problems that many diseases cause.
The measles vaccine has had the most significant impact on reducing infant mortality, saving nearly 94 million lives over the past 50 years. This vaccine will likely remain the top contributor to preventing infant deaths in the future. Other vaccines that have contributed to reducing infant mortality include those for diphtheria, Haemophilus influenzae type B, hepatitis B, Japanese encephalitis, meningitis A, pertussis, invasive pneumococcal disease, polio, rotavirus, rubella, tetanus, tuberculosis, and yellow fever.
Vaccines not only save lives but also prevent long-term disabilities and promote health equity. For example, the vaccine for meningitis A has nearly eliminated the disease and prevented long-term effects such as hearing loss, seizures, limb amputations or weakness, scarring, vision problems, and cognitive difficulties. The human papillomavirus (HPV) vaccine can prevent up to 90% of HPV-related cancers, including almost all cases of cervical cancer.
Despite the success of vaccines, rising hesitancy and declining confidence in vaccine safety threaten to reverse decades of progress. Misinformation and funding cuts could affect vaccination rates and put more lives at risk.
