Measles is a highly contagious disease that can cause serious illness and even death. While measles was once a common childhood illness, the introduction of the measles vaccine in the 1960s led to a significant decline in cases worldwide. However, despite the effectiveness of the vaccine, measles outbreaks continue to occur. This is often due to declining vaccination rates, which leave communities vulnerable to the spread of the disease. While the majority of cases occur in unvaccinated individuals, there is a small risk of infection for those who have received only one dose of the vaccine or have unknown vaccine status. As such, it is important to understand the factors contributing to vaccine hesitancy and how to address them to prevent future outbreaks.

What You'll Learn
Measles is a highly contagious and potentially deadly disease
Measles typically causes a cough, red eyes, high fever, and a rash. However, it can lead to more severe health problems and complications, especially in children under five years old. These complications can include pneumonia, encephalitis, brain damage, and pregnancy complications. Measles weakens the immune system, making it harder for the body to fight off other diseases.
The best way to protect against measles is through vaccination. The measles, mumps, and rubella (MMR) vaccine is safe and effective, and two doses provide up to 97% protection against the disease. In the United States, measles was declared eliminated in 2000 due to high vaccination rates. However, falling vaccination rates and misinformation have led to recent outbreaks in the country.
While it is uncommon for fully vaccinated individuals to develop measles, breakthrough infections can occur during outbreaks. The majority of cases are among those who are unvaccinated. It is important to maintain high vaccination rates to prevent measles outbreaks and reduce the risk of severe complications and deaths associated with the disease.
In summary, measles is a highly contagious and potentially deadly disease that can cause severe health complications. Vaccination is the best way to protect against measles and prevent outbreaks. Maintaining high vaccination rates is crucial to ensuring community immunity and protecting those who are most vulnerable to the disease.

The measles vaccine is safe and effective
Measles is a highly contagious, airborne, and potentially fatal disease. It is caused by a virus that can live in the air for several hours after an infected person coughs or sneezes. In a completely susceptible population, one person with measles will infect an average of 12 to 18 other people. Before the measles vaccine was introduced, an estimated 48,000 people were hospitalized, and 400 to 500 people died in the United States each year.
The measles, mumps, and rubella (MMR) vaccine is safe and effective. The MMR vaccine has been exhaustively studied and proven safe. Two doses of the MMR vaccine are about 97% effective at preventing measles, while one dose is about 93% effective. The MMR vaccine is safe for breastfeeding women and their babies. It is also safe to receive another dose if you are already immune to measles, mumps, or rubella. However, people with weakened immune systems, those who have had organ transplants, or those receiving certain medical treatments may not be eligible for the MMR vaccine.
While no vaccine is 100% effective, the MMR vaccine provides effective protection against measles for most people. Vaccines, like any medicine, can have side effects, but these are usually mild and go away on their own. Serious reactions to the MMR vaccine are rare. The most common side effects are soreness at the vaccination site, fever, and pain and stiffness in the joints. Some people may also develop a mild rash within three weeks of vaccination, but this is typically not a concern unless there has been exposure to measles.
Falling vaccination rates and misinformation about the MMR vaccine have contributed to outbreaks of measles in the United States. Measles was declared eliminated in the country in 2000, but there has been a recent increase in cases, with 1,288 cases reported across 39 jurisdictions as of early July. The majority of these cases were among unvaccinated individuals. To prevent measles outbreaks and protect against the disease, it is essential to maintain high vaccination rates and ensure that individuals receive the recommended number of MMR vaccine doses.

Vaccination rates are falling, leading to more outbreaks
Measles is a highly contagious airborne disease that can be prevented with a safe and effective vaccine. Two doses of the measles, mumps, and rubella (MMR) vaccine are 97% effective at preventing measles, and one dose is 93% effective. Before the measles vaccine was introduced, an estimated 48,000 people were hospitalized and 400-500 people died in the United States each year.
However, despite the effectiveness of the vaccine, measles outbreaks continue to occur due to falling vaccination rates. In the United States, MMR coverage among kindergarteners is decreasing and is now below the 95% coverage target needed for community immunity (herd immunity). This has led to a rise in measles cases, with 1,274 individual cases confirmed in 31 states from January to December 2019. The majority of these cases were among unvaccinated individuals.
Falling vaccination rates have also been observed in more than 30 states across the US, with coverage against measles, mumps, rubella, chickenpox, polio, and pertussis declining. This has raised concerns about the return of previously eliminated diseases. For example, a recent study predicted that a 10% decline in MMR vaccine coverage could result in more than 11 million measles infections over 25 years, while a 50% decline could lead to 51 million measles cases.
The consequences of falling vaccination rates are already being felt in certain communities. In Texas, a measles outbreak among mostly school-aged children has occurred, with at least 15 confirmed cases. This outbreak is believed to have originated in communities with low vaccination rates. Similarly, a measles outbreak in the southwestern United States has resulted in 327 confirmed cases in Texas and 43 in neighboring New Mexico, with the majority of cases occurring in a Mennonite community.
As vaccination rates continue to decline, health experts warn of the increased risk of widespread outbreaks and the return of diseases like measles and polio. Maintaining high vaccination coverage is crucial to preventing the spread of vaccine-preventable diseases and protecting vulnerable individuals in the community.

Misinformation about vaccines is contributing to lower vaccination rates
Measles is a highly contagious airborne disease that can lead to severe health issues and even death. It is also vaccine-preventable. Before the measles vaccine was introduced, an estimated 48,000 people were hospitalized and 400-500 people died in the United States each year. In 2023, 107,500 people globally died from measles, mostly unvaccinated or under-vaccinated children under 5.
The measles vaccine was first licensed for public use in 1963, and mass vaccination programs were introduced at the national level from the 1960s onwards. The first internationally focused measles immunization programs took place in Africa from 1966. The measles, mumps, and rubella (MMR) vaccine is very safe and effective. When more than 95% of people in a community are vaccinated, most people are protected through herd immunity.
However, in recent years, MMR coverage in the United States has been decreasing and is now below the 95% target, especially in certain communities. This has contributed to measles outbreaks in the country. From January 1 to December 31, 2019, 1,274 individual cases of measles were confirmed in 31 states, with the majority of cases among unvaccinated people.
Misinformation about vaccines has been identified as a significant contributor to lower vaccination rates and increased vaccine hesitancy. A study by Columbia University's Mailman School of Public Health found that the high volume of misinformation online can override more reliable sources, limiting the effectiveness of high-quality information campaigns. Social media platforms, in particular, have been identified as the "epicenter of misinformation," with anti-vaccine messages contributing to negative opinions about vaccines and even the resurgence of measles. Exposure to online misinformation has been linked to increased health risks and vaccine hesitancy, with a negative relationship observed between misinformation and vaccination uptake rates.
To counter the impact of misinformation, successful messaging campaigns should affirm cultural values, address reasons for hesitancy, and build trust through trusted voices such as community health workers, faith leaders, and military members. Additionally, social media platforms need to play a more proactive role in addressing misinformation and promoting accurate information.

The importance of herd immunity in preventing measles outbreaks
Measles is an airborne, highly infectious, and potentially severe rash illness. It is one of the most contagious infectious diseases and can be deadly, especially for unvaccinated or under-vaccinated children under 5. In 2023, measles caused an estimated 107,500 deaths globally, mostly among children under 5.
Before the measles vaccine was introduced, an estimated 48,000 people were hospitalized and 400–500 people died in the United States each year. The first measles vaccine was licensed for public use in 1963, and mass vaccination programs were introduced at the national level from the 1960s onwards. In 2000, measles was declared eliminated in the United States, meaning there was no longer any endemic measles transmission within the country. This was a historic public health achievement made possible by high vaccination rates.
However, in recent years, there has been a decline in vaccination coverage in some communities due to misinformation, access issues, or vaccine hesitancy. This has led to measles outbreaks even in countries where the disease was previously eliminated. Globally, measles deaths increased by 43% between 2021 and 2022, largely due to decreased vaccine coverage during the COVID-19 pandemic.
Herd immunity is crucial in preventing measles outbreaks. Herd immunity refers to the concept that when a large portion of a community is immune to a disease, it provides protection for those who are not immune, including infants, people with weakened immune systems, and those who cannot receive the vaccine due to medical reasons. When most people in a community are vaccinated, the virus cannot spread easily, even if a case is introduced by travel or contact with an unvaccinated person.
To achieve herd immunity against measles, experts estimate that about 95% of the population needs to be immune. This can be achieved through high vaccination rates. The measles, mumps, and rubella (MMR) vaccine is highly effective, with two doses providing about 97% protection against measles. Keeping MMR vaccination rates high is essential to preventing measles outbreaks and protecting vulnerable members of the community.
