There were 285 new cases of measles in the U.S. in 2024. Measles, also known as rubeola, is an infectious disease that is highly contagious and affects mostly children. Common symptoms of measles include fever, runny nose, sore throat, cough, and a rash. Although death rates from measles have decreased around the world, it is still responsible for around 81,000 deaths worldwide per year. Measles vaccination The main reason for the decrease in measles cases and deaths is due to high vaccination rates. The widely used MMR vaccine protects against measles, mumps, and rubella and is safe and effective. In 2023, around 91 percent of adolescents in the U.S. aged 13 to 17 years had received an MMR vaccination. However, in recent years there has been a rise in measles cases in many parts of the world due to vaccine hesitancy. Vaccine hesitancy Vaccine hesitancy refers to a refusal or reluctance to have children vaccinated, despite the overwhelming evidence that vaccines are safe and effective. This hesitancy comes from a misunderstanding of the ingredients in vaccines and how they work, a mistrust of doctors and pharmaceutical companies, and belief in the unfounded associations of vaccines with other diseases and disorders.

In 1970, there were 22.79 new cases of measles per 100,000 population in the United States. However, this rate dropped to .08 in the year 2024. This statistic shows the number of new cases of measles per 100,000 population in the United States from 1919 to 2024.

In 1919, there were almost 13 deaths from measles per 100,000 population in the United States. However, this rate had dropped to zero by the year 2021. In early 2025, an outbreak of measles in Texas resulted in the death of a child. This was the first measles death in the United States since 2015. Measles is a highly contagious disease, that is especially dangerous for children. However, vaccines have significantly decreased the rate of cases and deaths in the United States.

From January 1 to April 3, 2025, there were 607 measles cases in the United States. So far, Texas has reported the highest number of measles cases in 2025. Measles is a highly contagious disease that can be especially dangerous for young children. Vaccines against measles resulted in a significant decrease in cases in the United States over the last few decades; however, increasing vaccine hesitancy and skepticism has been blamed for recent outbreaks.

Immunization, measles (% of children ages 12-23 months) in United States was reported at 92 % in 2023, according to the World Bank collection of development indicators, compiled from officially recognized sources.

Project Tycho data include counts of infectious disease cases or deaths per time interval. A count is equivalent to a data point. Project Tycho level 1 data include data counts that have been standardized for a specific, published, analysis. Standardization of level 1 data included representing various types of data counts into a common format and excluding data counts that are not required for the intended analysis. In addition, external data such as population data may have been integrated with disease data to derive rates or for other applications. Version 1.0.0 of level 1 data includes counts at the state level for smallpox, polio, measles, mumps, rubella, hepatitis A, and whooping cough and at the city level for diphtheria. The time period of data varies per disease somewhere between 1916 and 2011. This version includes cases as well as incidence rates per 100,000 population based on historical population estimates. These data have been used by investigators at the University of Pittsburgh to estimate the impact of vaccination programs in the United States, published in the New England Journal of Medicine: http://www.nejm.org/doi/full/10.1056/NEJMms1215400.

In 2023, there were a total of 58 cases of measles in the United States. Around 72 percent of measles cases that year were attributed to unvaccinated individuals. Meanwhile, those with two doses of vaccination only accounted for just three percent of cases. This statistic shows the number of measles cases reported in the United States from 2020 to 2024, by vaccination status.

IntroductionVaccine-preventable diseases continue to cause morbidity and mortality despite the introduction of childhood immunizations. Recent media reports from Canada and the United States of America (USA) have highlighted a rise in childhood illnesses like measles, which could have been prevented with vaccines. Parents play a pivotal role in ensuring their children receive timely vaccinations. Immunization reminders can help parents who forget or miss vaccination appointments. In the USA, current literature indicates that Black children have lower vaccination rates than other racialized children and vaccine reminders may improve measles vaccine uptake among Black parents. However, there is limited data in Canada on vaccine uptake in children of Black parents, with evidence suggesting vaccine hesitancy among the Black population.ObjectiveThis scoping review aims to map out existing literature on immunization reminder strategies among parents to identify their impact in improving childhood vaccination rates and promoting child health.Inclusion criteriaThe review will include studies conducted in Canada and the United States of America that focus on immunization reminders for parents who have children under six years and published in English between 2015 and 2025.MethodsDatabase and hand-searching of journals and gray literature will be carried out to retrieve pertinent articles. Studies that meet the inclusion criteria will be eligible for selection. The process of selecting eligible studies will then be summarized on a PRISMA-ScR chart. Collated in data-extraction tables will be authorship information, publication date, methods and findings. The findings, key arguments and themes will be analyzed using a thematic analysis and summarized using a narrative summary.ConclusionThis review will contribute to the existing knowledge on parental preferences for vaccine reminder strategies and their usefulness in increasing childhood vaccination rates. The findings will inform and improve public health strategies aimed at boosting vaccine uptake among children.

In the year 2000, there were around 3,397 deaths due to measles in Europe. This number dropped to just 222 in 2023. This statistic shows the estimated number of deaths due to measles worldwide in 2000 and 2023, by region.

Abstract

The National Post Measles Campaign Coverage Survey (PMCCS) was conducted following measles campaign targeting children aged 9 and 59 months in conducted in Nigeria between November 2017 and March 2018 in Nigeria. The survey was commissioned by the National Primary Healthcare Development Agency (NPHCDA) and implemented by the National Bureau of Statistics. Technical assistance was provided by the World Health Organization while funding was provided by PMCCS provides information on the children receiving measles vaccination during the measles campaign. PMCCS was carried out from January to April 2018 and covered 6819 households with 10151 children aged between 9 and 59 months. The population sampled for the PMCCS is representative of children aged 9 to 59 months nationally and in all 36 states and FCT- Abuja.

The primary objective of the survey was to determine the coverage of measles vaccination in all states, the Federal Capital Territory, Abuja and nationally. Secondary objectives of the survey were: 1. To stratify SIA coverage estimates by age group (9-11 months, 12-59 months) 2. To stratify SIA coverage estimates by sex 3. To identify key communication channels that were effectively used for the campaign 4. To determine reasons for non-vaccination of eligible children during the campaign 5. To determine occurrence of adverse events following immunization (AEFI) during the campaign 6. To determine the proportion of children receiving the first dose of measles vaccine during the campaign (i.e., previously unvaccinated)

Sample survey data [ssd]

Sampling procedure

PMCCS was based on the National Population Commission master sampling frame based on the 2006 Nigeria Housing and Population Census. The sampling frame developed under the National Integrated Survey of Households (NISH2). Areas of the country that are inaccessible due to security reasons were excluded from the sampling frame including specific Local Government Areas (LGAs) in Borno and Adamawa states. Interpretation of results from these areas should therefore be conducted in light of these exclusions.

A stratified two stage - cluster sampling design was chosen for the 2017/18 PMCCS. Reporting strata were 36 state and FCT- Abuja.

The first stage selection involved the selection of EAs in each state and the FCT (Abuja) from the master sampling frame. A total of 30 EAs were selected from the sampling frame and with the selection probability of each EA was recorded for incorporation into household weights.

Following first stage sampling, household listing was conducted in the selected EAs to map all structures and boundaries and also identify households with children aged between 9 and 59 months eligible for second stage selection. Household listing was conducted between the 2nd and 9th of December 2017.

Second stage selection of households to be interviewed was conducted by the National Bureau of Statistics (NBS) using simple random sampling without replacement from the list of households with eligible children aged 9 to 59 months. Seven (7) households with eligible children were randomly selected from each of the 30 enumeration areas in every state.

Mode of data collection

Face-to-face [f2f]

Research instrument

The survey questionnaire consisted of the following: - Household Information Panel (Household rosters) - Individual Questionnaire: This questionnaire was administered to all mothers or caregivers who care for a child that lives with them and was within the age of 9 months - 59 months (5 years).

Cleaning operations

Data collection was using Census and Survey Program (CSPro) software running on android computers. Range checks and skip patterns were predefined in the data entry program to ensure that only all valid responses were collected and there were responses to all applicable questions ensuring enhanced data quality and completeness of collected data. On completion of the household roster, only age-eligible respondents were presented to the interviewer for interviewing and information had to be collected on all selected respondents before a household completion status was generated by the CAPI software.

Response rate

Nationally, the household response rate was 96.2 percent. The household response rate was generally higher in rural areas compared to urban areas with the response rate being 97.4 percent and 92.6 percent respectively. Notably, the household response rates in Lagos, Ebonyi, Oyo, Abuja and Abia were below 90 percent. Despite a planned sample size of 7 eligible households per EA, this planned sample was only achieved in 8 states. In a majority of the states, there were less than 7 households with eligible children available for selection to the survey and were all selected in the EA.

Sampling error estimates

Assuming an expected coverage of 90%, half-width confidence interval around state-level estimates of 8% (i.e., 90% +/- 8% coverage estimate) with an alpha level (type I error) of 5%, the effective sample size (i.e., sample size per stratum under a simple random sampling assumption) was n = 101. This level of precision allowed for estimation of coverage with acceptable precision at state, zonal and national levels1.

Data appraisal

Series of tables and graphs were generated.

This statistic shows the annual number of cases of select infectious diseases in the U.S. before and after the development and use of vaccinations as of 2022. Before the use of vaccinations there were an estimated 530,217 new cases of measles per year in the United States. This number dropped to 121 new cases in 2022 due to the development and use of vaccinations.

As of 2017, around 91.5 percent of children in the U.S. aged 19 to 35 months had been vaccinated against measles, mumps and rubella (MMR). The MMR vaccine is widely used around the world and is recommended by the Centers for Disease Control and Prevention (CDC) for adults who don’t have immunity and all children.

Measles

The number of cases of measles in the United States has dropped significantly since the introduction of the MMR vaccination. However, there has been a recent increase in measles cases, due to the growth of the vaccine hesitancy movement. Despite claims from this movement, the MMR vaccine is safe and effective. One dose of the MMR vaccine is around 93 percent effective against measles, while two doses is 97 percent effective.

Mumps

The MMR vaccine has resulted in a similar decrease in the rate of mumps cases in the U.S. One dose of the MMR vaccine is 78 percent effective against mumps, while two doses is 88 percent effective. Although the MMR vaccine is safe and effective, like any medicine it can have side effects. Common side effects include fever, a mild rash and temporary joint pain and stiffness.

Rank, number of deaths, percentage of deaths, and age-specific mortality rates for the leading causes of death, by age group and sex, 2000 to most recent year.

The number of confirmed cases of rubella, a vaccine-preventable disease, in the United States has decreased dramatically since 1998. This statistic shows the number of cases of rubella in the United States reported each year from 1998 to 2021.

Although there has been an overall decline in a number of vaccine-preventable diseases in the U.S., the number of pertussis cases has increased since 1980. This statistic shows the number of reported cases of select vaccine-preventable diseases in the U.S. from 1980 to 2022.

New spikes of measles outbreaks in the European Economic Area (EEA) were reached in 2024, with over ***** cases of measles reported in March 2024, the highest monthly figure since June 2011. The recent increase in cases could be a result of the growing vaccine skepticism movement in some European countries. Incidence by age and country In 2023, nearly ** percent of all measles cases in the European Economic Area (EEA) were reported among children aged one to four years old. The age group between five and nine years followed with almost ** percent of the cases. In the same year, Romania reported the highest number of measles cases among all countries in the EEA with nearly ***** cases, far more than any other country in the region. Similarly, the highest incidence rate of measles in the same area was reported in Romania, with **** cases per one million population. Vaccination figures In 2023, nearly ** percent of the children in the European Economic Area (EEA) received their first dose of measles vaccines, while around ** percent received the second dose of the immunization. In that year, around **** in **** children who contracted measles in the EEA were unvaccinated, while only around **** percent of the cases were reported in children who had received * or more doses of measles immunization.

In 2024, around 1,185 petitions were filed with the United States National Injury Compensation Program (VICP) seeking compensation for injury or death caused by vaccines. However, just because a petition was filed seeking compensation for injury or death due to a vaccination does not mean that compensation was awarded. Over half of all such petitions filed in the U.S. since 1988 have been dismissed, and in 60 percent of cases in which compensation was awarded it was still not determined whether the alleged vaccine caused the alleged injury. The impact of vaccinations Vaccinations in the United States have had a significant impact on infectious diseases. For example, as of 2017, there are only about 120 new cases of measles per year, compared to over half a million annual cases before the use of vaccination. Vaccinations in the U.S. have also greatly decreased the number of annual cases of hepatitis A and B, rubella, and tetanus. COVID-19 vaccination hesitancy Vaccine hesitancy is a persistent issue in the United States. The issue became especially pertinent during the COVID-19 pandemic in which many people in the United States expressed reluctance to getting a COVID-19 vaccination. In December 2020, 59 percent of adults in the United States who stated they would definitely not or probably not get a COVID-19 vaccine said so because they were worried about possible side effects, while 55 percent said they probably wouldn’t get a COVID-19 vaccination because they do not trust the government to make sure the vaccine is safe and effective. Shockingly, one survey found that even 29 percent of health care workers stated they would probably or definitely not get a COVID-19 vaccine.
