Global vaccine coverage
This chart shows the global vaccination coverage of one-year-olds with some of the most important vaccines recommended by the WHO. For many essential vaccines, coverage is now much higher than 80%. However, the rates of vaccination are still not sufficient.1 If you click the play button you see that the coverage for most vaccines has increased substantially over time. The DTP vaccine (against diphtheria, tetanus, and pertussis) is often used as a key metric for global vaccination coverage bec...
How vaccines work & herd immunity
Vaccines prime us to fight against infectious diseases. The basic mechanism by which vaccines work is simple: vaccines include a weakened or killed form of the pathogen, or just a part of the pathogen, which stimulates our immune response. This means that when we encounter the real pathogen later on, our immune system is better able to recognize it and protect against it. When a person is immune to a disease, they can act as a barrier to slow down or prevent the spread of disease to other peo...
Since the first vaccine — the smallpox vaccine developed by Edward Jenner in 1796 — many more vaccines have been developed. As of 2023, effective vaccines are available against 33 human diseases.4
People do not know how well we do in global vaccination
Today vaccines protect millions of people around the world from infectious diseases. In this fight, we are much, much further ahead than most people realize. People around the world have been asked the question: “How many of the world’s 1-year old children today have been vaccinated against [a particular] disease?”in large-scale surveys. For diphtheria, tetanus and pertussis, the correct answer was 86% in 2015. That’s the share who have been vaccinated with the third dose of the DTP vaccine....
What determines if vaccinations are compulsory?
Countries vary in whether vaccination is compulsory, mandatory (required according to specific mandates), or voluntary. Navin and Largent (2017) provide a helpful distinction between these policies. A compulsory policy is when refusing vaccination is illegal, while mandatory vaccination is when certain goods and services are limited for not vaccinating.10 Which policy is followed has depended much on historical legacy, which becomes clear when one considers some of the different regulations a...
Which countries include vaccines in their immunization schedules?
Several vaccines, including rubella, mumps, and rotavirus, are included in immunization schedules in many countries around the world. This means these vaccines are provided and recommended through routine services. This doesn't necessarily tell us how many children receivethese vaccines in each country. The vaccines may or may not be mandatory and their coverage rates may vary widely. Similarly, when countries do not have a vaccine in their schedule, this does not mean that the vaccine is com...
Diseases preventable through vaccination
The chart shows the number of global deaths caused by some of the most common and serious vaccine-preventable diseases. By selecting "change country" it is possible to see this change for any country in the world and extending the timeline will let you see the change in deaths over time. There are more diseases for which vaccines are available now and even more are under development currently. The WHO publishes list of 26 diseasesfor which vaccines are available — including Japanese encephali...
Diphtheria, Tetanus, and Pertussis vaccine
Diphtheria, tetanus, and pertussis are all bacterial diseases, and a combination vaccine (called the DTP vaccine) is commonly used to protect against all three diseases. 1. Diphtheria is a serious bacterial infection that affects the throat and nose. It can lead to breathing difficulties, heart failure, and paralysis. 2. Tetanus is a disease caused by the bacteria Clostridium tetani. It can be caught from dirt that enters wounds, which especially affects mothers giving birth and newborns. The...
Measles vaccine
Measles is a highly contagious virus spread through airborne particles. It causes serious disease, especially among children. The world map shows the share of children vaccinated with the first dose of measles vaccine. You can switch to the "chart" view to see the global coverage against vaccines. The measles vaccine was developed in 1963. In 1980, less than 20% of children were vaccinated globally. By 2021, that figure was over 80%.
