Vaccines are technologies that help protect people against developing diseases. Since the invention of the first vaccine, against smallpox, vaccines have greatly reduced the prevalence of diseases everywhere in the world.

This page describes which vaccines are available and where they are used, what their impact on global health is, and how the world can make more progress against early death and disease with the help of vaccines.

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 because it involves three doses, and is a good indicator of access to routine immunization services.

In 2021, coverage of the third dose of DTP was 81%. This means that 81% of one-year-olds had received the third dose of the DTP vaccine and 19% had not.

In 2021, only 49% of one-year-olds globally received the rotavirus vaccine, which protects children from diarrheal diseases — one of the leading causes of child mortality. Similarly, the pneumococcal vaccine that protects children from pneumonia — the leading cause of child mortality — only reached 51% of one-year-olds.²

Prosperity and vaccination coverage

Why do not all children in the world receive vaccinations?

The vaccine coverage against diphtheria, pertussis, and tetanus (DTP) is a good marker of the strength of a country’s immunization programs since several administrations are required.

This chart shows that poorer countries tend to be those with lower vaccination coverage for DTP. Similarly, countries in which a large share of the population is living in extreme poverty often — but not always — have lower immunization rates, as this related chart shows.

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 people. Populations that have more immunity are better able to contain the spread of the disease. This protects the rest of the population, especially those who cannot be vaccinated, such as very young infants and those who have immune conditions.

The "herd immunity threshold" refers to a level of immunity in the population above which the spread of disease slows down, or is unable to cause a lasting outbreak. This threshold depends on the context — it varies between different diseases and populations, and it can change over time.³

Progress made with vaccination

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

Smallpox and the origin of vaccination

Vaccination has a long history. An early form of vaccination was referred to as "variolation" or more broadly as "inoculation”. Practiced for a long time in Asia, this was an ancient technique of deliberate smallpox infection, in which dried smallpox scabs were blown up the nose, to infect the person with a milder form of the disease. By the 1700s, variolation had spread to Africa, India and the Ottoman Empire, followed by Britain and America, where the method of infection more frequently used a skin puncture.

Variolation could be effective but carried risks. If the pathogen wasn’t dried up or inactivated properly, then people who were variolated could contract the severe form of smallpox, which could be fatal, and could also spread the disease to others.

In 1796, the English physician Edward Jenner demonstrated another method of inoculation, in which he relied on cowpox. Cowpox is a similar disease to smallpox, and it had previously been observed that an infection with cowpox can protect against smallpox.

Jenner conducted an experiment using matter from a cowpox lesion to inoculate his gardener’s eight-year-old son James Phipps. Two months later Jenner exposed the boy to smallpox lesion matter and when Phipps did not develop smallpox, he concluded that he was protected against the disease. Jenner called the procedure "vaccination" after "vacca", the Latin word for cow, because of the origin of this first vaccination from the cowpox virus.

Following the findings of Jenner, the smallpox vaccine went through many iterations, with the newer vaccines produced by modern cell culture techniques (passing the virus through cell culture to make the vaccine safer).

By the middle of the 20th century, confidence grew that smallpox could be the first disease that humankind might be able to eradicate. In 1967, the WHO launched a global eradication of smallpox program. Mass vaccination of over 80% of populations was needed, but people who were nomadic or lived in politically unstable regions posed particular problems.

A number of innovations came in the development of the foot-powered injector, called the “ped-o-jet”, and the bifurcated needle, which was efficient and cheap.

To reach large sections of the population, the epidemiologist William Foege developed "Eradication Escalation (E2)" to contain smallpox outbreaks during October (the seasonal low point of smallpox transmission where prevention of just a few cases could stop a smallpox chain transmission).

Other obstacles in the program included forcibly vaccinating an Indian religious leader to convince his followers to be vaccinated, negotiation of ceasefires for vaccine transport in war-torn Nigeria, vaccinating in concentric rings around an outbreak, and cash bounties to reward the reporting of smallpox cases.

Finally, in 1977, the last case of naturally contracted smallpox was reported in Somalia — in a health worker called Ali Maow Maalin — and in 1980 the WHO announced that smallpox had been eradicated.

Vaccine innovation

The chart here shows a timeline of innovation in the development of vaccines as of 2020. Each bar begins in the year when the pathogenic agent was first linked to the disease, and the bar ends in the year when a vaccine against that pathogen was licensed in the United States.

For some diseases, there has been a relatively short period between when the pathogen was linked to the disease and when a vaccine was developed.

Before 2020, the quickest development was for measles. The measles virus was linked to the disease in 1953 and the vaccine was licensed in the U.S. in 1963.

In 2020, this record was broken when several vaccines were developed within just one year to fight the coronavirus pandemic.

Progress against vaccine-preventable diseases in the US

The visualization here shows the reduction in cases and deaths from vaccine-preventable diseases in the United States after the introduction of each vaccine. This data was published by Roush and Murphy (2007).⁵

For several diseases, the US has achieved a 100% reduction of cases and deaths and for many other diseases, the reduction is often very substantial as well.

The development of the vaccine against measles and the history of measles in the US

The introduction of a vaccine was not the only reason for progress against these diseases, as the visualization shows.

The death rate of measles was falling in high-income countries such as the US before the vaccine was introduced in 1960 — this is best seen by switching from the linear to the logarithmic axis. Improved living conditions, nutrition, and medical advancements meant that contracting measles became less likely to be fatal.

But the rate of new cases of measles remained stable until the measles vaccine was introduced — as the chart shows.⁷

A chart showing the total number of cases and deaths can be seen here.

Global decline in vaccine-preventable diseases

The chart shows there has been a decline in the deaths caused by vaccine-preventable diseases, among children under five years old. This includes deaths caused by measles, tuberculosis, tetanus, meningitis, and other diseases.

But it also shows how much more needs to be done — even in recent years, millions of deaths have been caused by diseases that can be prevented by vaccines. In the following sections, we cover these diseases in more detail.

Public support and skepticism

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.

But in all countries that were surveyed, people’s answers were much too pessimistic.

For example, Americans thought that only 35% of the world's children are vaccinated, while the true coverage was 50 percentage points higher.⁸ In Japan, people were even more pessimistic and thought that only 18% were vaccinated.

As is often the case in questions on global development, we again see that people in poorer countries have a more accurate view of the world: in Kenya and Senegal people thought that vaccines reached around two-thirds of all children in the world, but even these highest estimates were 20 percentage points too low.

The chart illustrates how outdated people's answers are. Most individuals think that the global vaccination coverage today is as low as it was in the 1980s or even earlier.

Here we look at results from the largest global survey to date – the Wellcome Global Monitor – on attitudes to vaccination across the world.

Skepticism to vaccines and what to do about it

What effect do public attitudes have on vaccine coverage rates, and what can we do about skepticism to vaccines?

Vaccine policy

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 and their history around the world:

Compulsory vaccination: Many Eastern Bloc countries introduced compulsory vaccination during the communist era. Italy and France also had compulsory vaccination for three diseases, but increased this number to 11 in January 2018 in response to a drop in vaccination rates.

Mandatory vaccination: Some countries, such as the United States, have mandates for vaccination where a child is required to be vaccinated to enter state school or daycare.

An early case in the US paved the way for state jurisdiction to protect public health in light of personal liberty.¹¹ In Jacobson v. Massachusetts (1905) the Supreme Court ruled that states have the authority to require vaccination against smallpox during a smallpox epidemic. Since then the US has had a history of school vaccination requirements. The increased number of children in public schools as a result of the compulsory school attendance law led to an increased risk of smallpox outbreaks, through close contact in large crowded classrooms.¹²

Similarly, in Australia, two policies penalize parents for not vaccinating their children. The "No jab no play" policy removed unvaccinated children from state-sponsored childcare. The 2016 "No jab no pay" policy removes state welfare by not providing the universal "Family Allowance" welfare payments for parents who are conscientious objectors of vaccination.

Which countries have mandatory childhood vaccination policies?

How do policies on childhood vaccinations vary across the world?

Voluntary vaccination: Some countries where vaccination is voluntary had early pushback against vaccination, such as the UK and the Netherlands. In 1853, a law was passed in England and Wales requiring universal vaccination against smallpox, but opposition from anti-vaccinationists led to laws being passed to allow for conscientious objection.¹³

Vaccination requirements for country entry: For countries in Africa and South America where yellow fever is endemic or where the mosquito vector is present a certificate of proof of vaccination is required. Only then will the country issue a visa upon entry to that country to prevent the importation of this disease (particularly if travelers come from, or have visited other yellow fever endemic areas).¹⁴

In past centuries (17th to 19th), yellow fever was transported to North America and Europe, causing large outbreaks that disrupted economies and development, and in some cases decimated populations. Throughout the 18th and 19th centuries, yellow fever was among the most feared diseases in the ports of the Old and New World. Saudi Arabia is the only country that requires additional vaccinations for meningococcal disease and polio for pilgrims visiting Mecca.

One country where we can see the effect of variation in vaccination policy is the US. In the US states decide what vaccine exemptions are permitted for children who receive education in schools or use daycare.

In individual states, exemptions are granted for medical reasons but many states also allow for philosophical, personal belief, or religious exemptions. Some states only allow for medical exemption.

The chart here shows vaccination coverage and what exemptions are allowed for each state. Fewer exemptions generally mean higher vaccine coverage.

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 receive these 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 completely unavailable in those countries, as it may be optional or available commercially.

In the map, you can see which countries include rubella vaccines in their national immunization schedules. Rubella vaccines became available for the first time in 1969, starting in the United States, where it was developed.¹⁶ It was included in the schedules of the United States and most European countries as early as 1994 (the first year of this dataset). Over time, more countries included it in their schedule.

But this took many years for some countries: for example, it took until 2018 for it to be included in countries such as Uganda and Congo.

As of 2021, some countries, such as Nigeria and South Africa, still do not include it in their schedules.¹⁷

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.

• Diphtheria is a serious bacterial infection that affects the throat and nose. It can lead to breathing difficulties, heart failure, and paralysis.
• 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 bacteria release a toxin that prevents the normal functioning of nerves, and can eventually lead to paralysis, difficulty breathing, and death.
• Pertussis, also known as whooping cough, is a highly contagious respiratory infection that is known for severe coughing fits followed by a "whooping" sound.

The chart shows the progress over time of DTP3 immunization coverage of children around the world. By clicking on any country you can see the change in that country over time.

One region that stands out is South-East Asia. While 82% of one-year-olds in the region were vaccinated in 2021, that figure had been just 7% in 1980.

Rotavirus vaccines

Rotavirus is the most common cause of diarrheal deaths in children globally.

Although rotavirus vaccines were first introduced in the United States in 2006, the death rate remains high because children in many countries do not receive vaccinations.

The efficacy of rotavirus vaccines has also been lower in countries with higher death rates.²⁰

In the chart, you can see the share of one-year-olds who were vaccinated against rotavirus.

Tuberculosis vaccine (BCG)

The chart here shows the coverage of the BCG vaccine, which protects against tuberculosis.

The BCG vaccine is one of the oldest and among the most widely used vaccines in the world.²³ It is based on a mild strain of Mycobacterium bovis, a bacterium that is closely related to Mycobacterium tuberculosis — the pathogen that causes TB.

The BCG vaccine became used in the 1920s in Belgium and France in small trials and after the Second World War its use was expanded to vaccinate children across Europe. In the 1950s, the WHO started recommending the use of the BCG vaccine globally.

BCG is effective at protecting children and adolescents from severe forms of TB and meningitis.^{24 25} However, studies have shown that the length of protection provided by the vaccine varies greatly depending on the populations studied.^{26 27} The reason for such variability is not clear, but factors such as different vaccine seed strains used for immunization and pre-existing immunity in people already exposed to other mycobacteria strains may be important.

Notably, the BCG vaccine protects against severe disease — but it does not protect people from getting infected with M. tuberculosis bacterium in the first place, and doesn’t prevent activation of latent TB if a person has already been infected. Therefore, the vaccine has limited effect on the prevention of M. tuberculosis spread in a population.²⁸
