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. If you click the play button you see that the coverage for most vaccines has increased substantially over time. The vaccine against diphtheria, tetanus and pertussis, is often used as the key metric for global vaccination coverage because i...
We know that vaccines save lives. But how many lives vaccines have they saved? The World Health Organisation (WHO) suggests that vaccination prevents 2-3 million deaths each year.2However, while we are certain that vaccines have saved millions of lives, calculating a precise number is impossible. Also the quoted number from the WHO is in important ...
In total there are now at least 28 human diseases against which we have effective vaccines.7The breakthrough that allowed us to get there was made in the late 18th century, the smallpox vaccine was the very first vaccine.
People do not know how well we actually 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. The first chart shows the evidence for this misperception. In this chart we plotted the survey responses that people gave when they were asked “How many of the world’s 1-year old children today have been vaccinated against some disease?”. The correct answer was 85.8%; this is the share of 1-year olds that received the third dose of the co...
How many people support vaccination across the world?
The London-based research charity The Wellcome Trust published their Wellcome Global Monitor in 2019 on attitudes to science and major health challenges. It is the world’s largest study of its kind, surveying over 140,000 people from over 140 countries. As part of the Gallup World Poll, the 30-question survey ran during 2018.26 The Wellcome Trust survey asked three core questions related to attitudes to vaccines: do people think that vaccines are important for children to have; do they think...
Does vaccine skepticism affect immunization coverage?
The crucial question to ask when considering the importance of vaccine skepticism is: does it actually have an effect on behaviour? Does it really affect the share of children who are vaccinated? In the chart we see the comparison of vaccination rates – here as the share of children who were immunized against diphtheria, pertussis and tetanus (DTP) in 2015, the latest year available – to the share of respondents in a given country who disagreed that vaccines are safe. You can also see this re...
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 when certain goods and services are limited for not vaccinating.28 Which policy is followed has depended much on historical legacy, which becomes clear when one considers some of the different regulations and...
Vaccine supply
Supply constraints have caused problems for country access to vaccination. One-third of 194 countries have run out of a vaccine for a month or longer – according to data submitted to WHO and UNICEF – and this includes both high- and low-income countries. In the US, the Centers for Disease Control and Prevention (CDC) stated that reasons for shortages were multi-factoral and included "...companies leaving the vaccine market, manufacturing or production problems, and insufficient stockpiles". I...
The cost of vaccines
There are five big pharmaceutical companies37 that account for 80% of vaccine production: Sanofi Pasteur, GlaxoSmithKline, Merck, Pfizer, and Novartis.38 Many vaccines are only provided by one or two suppliers. For newer vaccines there are often particularly few suppliers due to the high investment needed to develop a vaccine.39 As one would expect from competition, the WHO reports that when vaccines are produced by a greater number of suppliers it leads to a decline of the prices of those va...
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 against all three diseases is commonly used. 1. Diphtheria primarily infects the throat and upper airways and is fatal in 5 – 10% of cases. 2. Tetanus is not passed person-to-person but through spores of a bacteria living in soil and animal intestinal tracts. These bacteria enter the body through wounds and release a toxin that affects the nerves, which causes muscle stiffness and spasms. 3. Pertussis is a...
Measles vaccine
Measles is a highly contagious virus-caused disease that, despite a safe and effective vaccine being available, infects thousands of people globally. Around 90,000 people die because of measles every year, the huge majority of whom (87%) are children younger than 5. Measles vaccination has resulted in an 84% drop in measles deaths between 2000-2016.59 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 glob...
Calculating coverage
The coverage is calculated as the proportion of persons in a target age group who received a vaccine dose. Dates of vaccination are either taken from a child’s home-based record, recorded based on caregiver recall, or from health facility records. While appearing straightforward enough, several methodological problems of household survey respondent data on vaccination have been well documented.102 Questions have arisen about how accurately parents can recall child immunization history and the...
