Coverage with selected vaccines and exemption rates among children in kindergarten - United States, 2023-24 School Year
Seither R , Yusuf OB , Dramann D , Calhoun K , Mugerwa-Kasujja A , Knighton CL , Kriss JL , Miller R , Peacock G . MMWR Morb Mortal Wkly Rep 2024 73 (41) 925-932 In the United States, states and local jurisdictions set vaccination requirements for school attendance, conditions and procedures for exemptions from these requirements, grace periods for submitting documentation, and provisional enrollment for students who need more time to be vaccinated. States annually report data to CDC on the number of children in kindergarten who meet, are exempt from, or are in the process of meeting requirements. Data reported by 49 states and the District of Columbia (DC) for the 2023-24 school year were used for national- and state-level estimates of the following measures: complete vaccination with required doses of measles, mumps, and rubella vaccine (MMR), diphtheria, tetanus, and acellular pertussis vaccine (DTaP), poliovirus vaccine (polio), and varicella vaccine (VAR); exemptions from vaccination; and school attendance while meeting requirements. The 2023-24 kindergarten class became age-eligible to complete most state-required vaccinations during the COVID-19 pandemic, after schools had returned to routine in-person learning. Compared with approximated national coverage levels across all reported vaccines for the 2019-20 (95%) and 2022-23 (93%) school years, coverage dropped below 93% for the 2023-24 school year, ranging from 92.3% for DTaP to 92.7% for MMR. Exemptions increased to 3.3%, compared with those during the 2022-23 (3.0%) and 2021-22 school years (2.6%). Coverage with MMR, DTaP, polio, and VAR decreased in 35, 32, 33, and 36 jurisdictions, respectively, compared with the 2022-23 school year. Exemptions increased in 41 jurisdictions, with 14 reporting that >5% of kindergartners had an exemption from one or more vaccine. Efforts by health departments, schools, and providers are needed to ensure that students begin school fully vaccinated. |
Coverage with selected vaccines and exemption from school vaccine requirements among children in kindergarten - United States, 2022-23 school year
Seither R , Yusuf OB , Dramann D , Calhoun K , Mugerwa-Kasujja A , Knighton CL . MMWR Morb Mortal Wkly Rep 2023 72 (45) 1217-1224 U.S. states and local jurisdictions set vaccination requirements for school attendance and conditions and procedures for exemptions from these requirements. States annually report data to CDC on the number of children in kindergarten who meet, are exempt from, or are in the process of meeting requirements. National- and state-level estimates for complete vaccination with measles, mumps, and rubella vaccine (MMR); diphtheria, tetanus, and acellular pertussis vaccine (DTaP); poliovirus vaccine (polio); and varicella vaccine (VAR); exemptions from vaccination; and legally allowed kindergarten attendance while meeting requirements were based on data reported by 49 states and the District of Columbia (DC) for the 2022-23 school year. This kindergarten class became age-eligible to complete most state-required vaccinations during the COVID-19 pandemic. National coverage remained near 93% for all vaccines; exemptions were low but increased to 3%, compared with those during the 2021-22 school year (2.6%). At the state level, coverage with MMR, DTaP, polio, and VAR decreased in 29, 31, 28, and 25 states, respectively, compared with coverage during the 2021-22 school year. Exemptions increased in 40 states and DC, with 10 states reporting an exemption from at least one vaccine for >5% of kindergartners. Schools and providers should work to ensure that students are vaccinated before school entry, such as during the enrollment process, which is often several months before school starts. State and local provisional enrollment periods that allow students to attend school while on a catch-up schedule also provide the opportunity to fully vaccinate students and to prevent nonmedical exemptions resulting from lingering undervaccination due to COVID-19 pandemic-related barriers to vaccination, such as reduced access to vaccination appointments. |
Vaccination coverage with selected vaccines and exemption rates among children in kindergarten - United States, 2021-22 school year
Seither R , Calhoun K , Yusuf OB , Dramann D , Mugerwa-Kasujja A , Knighton CL , Black CL . MMWR Morb Mortal Wkly Rep 2023 72 (2) 26-32 State and local school vaccination requirements protect students and communities against vaccine-preventable diseases (1). This report summarizes data collected by state and local immunization programs* on vaccination coverage and exemptions to vaccination among children in kindergarten in 49 states(†) and the District of Columbia and provisional enrollment or grace period status for kindergartners in 27 states(§) for the 2021-22 school year. Nationwide, vaccination coverage with 2 doses of measles, mumps and rubella vaccine (MMR) was 93.5%(¶); with the state-required number of diphtheria, tetanus, and acellular pertussis vaccine (DTaP) doses was 93.1%**; with poliovirus vaccine (polio) was 93.5%(††); and with the state-required number of varicella vaccine doses was 92.8%.(§§) Compared with the 2020-21 school year, vaccination coverage decreased 0.4-0.9 percentage points for all vaccines. Although 2.6% of kindergartners had an exemption for at least one vaccine,(¶¶) an additional 3.9% who did not have an exemption were not up to date with MMR. Although there has been a nearly complete return to in-person learning after COVID-19 pandemic-associated disruptions, immunization programs continued to report COVID-19-related impacts on vaccination assessment and coverage. Follow-up with undervaccinated students and catch-up campaigns remain important for increasing vaccination coverage to prepandemic levels to protect children and communities from vaccine-preventable diseases. |
Vaccination Coverage with Selected Vaccines and Exemption Rates Among Children in Kindergarten - United States, 2020-21 School Year.
Seither R , Laury J , Mugerwa-Kasujja A , Knighton CL , Black CL . MMWR Morb Mortal Wkly Rep 2022 71 (16) 561-568 State and local school vaccination requirements serve to protect students against vaccine-preventable diseases (1). This report summarizes data collected for the 2020-21 school year by state and local immunization programs* on vaccination coverage among children in kindergarten in 47 states and the District of Columbia (DC), exemptions for kindergartners in 48 states and DC, and provisional enrollment or grace period status for kindergartners in 28 states. Vaccination coverage(†) nationally was 93.9% for 2 doses of measles, mumps, and rubella vaccine (MMR); 93.6% for the state-required number of doses of diphtheria, tetanus, and acellular pertussis vaccine (DTaP); and 93.6% for the state-required doses of varicella vaccine. Compared with the 2019-20 school year, vaccination coverage decreased by approximately one percentage point for all vaccines. Although 2.2% of kindergartners had an exemption from at least one vaccine,(§) an additional 3.9% who did not have a vaccine exemption were not up to date for MMR. The COVID-19 pandemic affected schools' vaccination requirement and provisional enrollment policies, documentation, and assessment activities. As schools continue to return to in-person learning, enforcement of vaccination policies and follow-up with undervaccinated students are important to improve vaccination coverage. |
Vaccination coverage with selected vaccines and exemption rates among children in kindergarten - United States, 2019-20 school year
Seither R , McGill MT , Kriss JL , Mellerson JL , Loretan C , Driver K , Knighton CL , Black CL . MMWR Morb Mortal Wkly Rep 2021 70 (3) 75-82 State and local school vaccination requirements serve to protect students against vaccine-preventable diseases (1). This report summarizes data collected by state and local immunization programs* on vaccination coverage among children in kindergarten (kindergartners) in 48 states, exemptions for kindergartners in 49 states, and provisional enrollment and grace period status for kindergartners in 28 states for the 2019-20 school year, which was more than halfway completed when most schools moved to virtual learning in the spring because of the coronavirus 2019 (COVID-19) pandemic. Nationally, vaccination coverage(†) was 94.9% for the state-required number of doses of diphtheria and tetanus toxoids, and acellular pertussis vaccine (DTaP); 95.2% for 2 doses of measles, mumps, and rubella vaccine (MMR); and 94.8% for the state-required number of varicella vaccine doses. Although 2.5% of kindergartners had an exemption from at least one vaccine,(§) another 2.3% were not up to date for MMR and did not have a vaccine exemption. Schools and immunization programs can work together to ensure that undervaccinated students are caught up on vaccinations in preparation for returning to in-person learning. This follow-up is especially important in the current school year, in which undervaccination is likely higher because of disruptions in vaccination during the ongoing COVID-19 pandemic (2-4). |
Centers for Disease Control and Prevention's School Vaccination Assessment: Collaboration with US state, local, and territorial immunization programs, 2012-2018
Mellerson JL , Street E , Knighton C , Calhoun K , Seither R , Underwood JM . Am J Public Health 2020 110 (7) e1-e6 Objectives. To describe the ongoing collaboration of the Centers for Disease Control and Prevention's (CDC's) school vaccination assessment with state, local, and territorial immunization programs to provide data to monitor school entry vaccination.Methods. Departments of health and education partner to collect data from public school, private school, and homeschooled kindergartners in the 50 US states, the District of Columbia, 2 cities, and the US territories. Immunization programs submit vaccination coverage and exemption data to the CDC, and the CDC reports these data annually via multiple sources.Results. Among the 50 states and the District of Columbia, the number of programs using a census for vaccination coverage data increased from 39 to 41 during the school years 2012-2013 to 2017-2018 (which for most states was August or September through May or June), and the number using a census to collect exemption data increased from 40 to 46. The number of states that reported sharing their local-level vaccination coverage data online increased from 11 in 2012-2013 to 31 in 2017-2018.Conclusions. Coverage data can be used to address undervaccination among kindergartners to work with communities and schools that are susceptible to vaccine-preventable diseases. As more states publish local-level data online, access to improved data provides the public more valuable information. (Am J Public Health.

Vaccination coverage with selected vaccines and exemption rates among children in kindergarten - United States, 2018-19 school year
Seither R , Loretan C , Driver K , Mellerson JL , Knighton CL , Black CL . MMWR Morb Mortal Wkly Rep 2019 68 (41) 905-912 State and local school vaccination requirements exist to ensure that students are protected against vaccine-preventable diseases (1). This report summarizes data collected by state and local immunization programs* on vaccination coverage among children in kindergarten in 49 states, exemptions for kindergartners in 50 states, and provisional enrollment and grace period status for kindergartners in 30 states. Nationally, vaccination coverage(dagger) was 94.9% for the state-required number of doses of diphtheria and tetanus toxoids, and acellular pertussis vaccine (DTaP); 94.7% for 2 doses of measles, mumps, and rubella vaccine (MMR); and 94.8% for the state-required doses of varicella vaccine. Whereas 2.5% of kindergartners had an exemption from at least one vaccine,( section sign) 2.8% of kindergartners were not up to date for MMR and did not have a vaccine exemption. Nearly all states could achieve the recommended >/=95% MMR coverage if all nonexempt kindergartners were vaccinated in accordance with local and state vaccination policies. |
Vaccination coverage for selected vaccines and exemption rates among children in kindergarten - United States, 2017-18 School Year
Mellerson JL , Maxwell CB , Knighton CL , Kriss JL , Seither R , Black CL . MMWR Morb Mortal Wkly Rep 2018 67 (40) 1115-1122 State and local school vaccination requirements exist to ensure that students are protected from vaccine-preventable diseases (1). This report summarizes vaccination coverage and exemption estimates collected by state and local immunization programs* for children in kindergarten (kindergartners) in 49 states and the District of Columbia (DC) and kindergartners provisionally enrolled (attending school without complete vaccination or exemption while completing a catch-up vaccination schedule) or in a grace period (a set interval during which a student may be enrolled and attend school without proof of complete vaccination or exemption) for 28 states. Median vaccination coverage(dagger) was 95.1% for the state-required number of doses of diphtheria and tetanus toxoids, and acellular pertussis vaccine (DTaP); 94.3% for 2 doses of measles, mumps, and rubella vaccine (MMR); and 93.8% for 2 doses of varicella vaccine. The median percentage of kindergartners with an exemption from at least one vaccine( section sign) was 2.2%, and the median percentage provisionally enrolled or attending school during a grace period was 1.8%. Vaccination coverage among kindergartners remained high; however, schools can improve coverage by following up with students who are provisionally enrolled, in a grace period, or lacking complete documentation of required vaccinations. |
Vaccination coverage for selected vaccines, exemption rates, and provisional enrollment among children in kindergarten - United States, 2016-17 school year
Seither R , Calhoun K , Street EJ , Mellerson J , Knighton CL , Tippins A , Underwood JM . MMWR Morb Mortal Wkly Rep 2017 66 (40) 1073-1080 State and local school vaccination requirements help protect students and communities against vaccine-preventable diseases (1). CDC reports vaccination coverage and exemption data for children attending kindergarten (kindergartners) collected by federally funded immunization programs in the United States.* The typical age range for kindergartners is 4-6 years. Although vaccination requirements vary by state (the District of Columbia [DC] is counted as a state in this report.), the Advisory Committee on Immunization Practices recommends that children in this age range have received, among other vaccinations, 5 doses of diphtheria, tetanus, and acellular pertussis vaccine (DTaP), 2 doses of measles, mumps, and rubella vaccine (MMR), and 2 doses of varicella vaccine (2). This report summarizes 2016-17 school year MMR, DTaP, and varicella vaccination coverage reported by immunization programs in 49 states, exemptions in 50 states, and kindergartners provisionally enrolled or within a grace period in 27 states. Median vaccination coveragedagger was 94.5% for the state-required number of doses of DTaP; 94.0% for 2 doses of MMR; and 93.8% for 2 doses of varicella vaccine. The median percentage of kindergartners with an exemption from at least one vaccine section sign was 2.0%, similar to 2015-16 (1.9%). Median grace period and provisional enrollment was 2.0%. Vaccination coverage remains consistently high and exemptions low at state and national levels. Local-level vaccination coverage data provide opportunities for immunization programs to identify schools, districts, counties, or regions susceptible to vaccine-preventable diseases and for schools to address undervaccination through implementation of existing state and local vaccination policies (1) to protect communities through increased coverage. |
Vaccine exemptions and the kindergarten vaccination coverage gap
Smith PJ , Shaw J , Seither R , Lopez A , Hill HA , Underwood M , Knighton C , Zhao Z , Ravanam MS , Greby S , Orenstein WA . Vaccine 2017 35 (40) 5346-5351 BACKGROUND: Vaccination requirements for kindergarten entry vary by state, but all states require 2 doses of measles containing vaccine (MCV) at kindergarten entry. OBJECTIVE: To assess (i) national MCV vaccination coverage for children who had attended kindergarten; (ii) the extent to which undervaccination after kindergarten entry is attributable to parents' requests for an exemption; (iii) the extent to which undervaccinated children had missed opportunities to be administered missing vaccine doses among children whose parent did not request an exemption; and (iv) the vaccination coverage gap between the "highest achievable" MCV coverage and actual MCV coverage among children who had attended kindergarten. METHODS: A national survey of 1465 parents of 5-7year-old children was conducted during October 2013 through March 2014. Vaccination coverage estimates are based provider-reported vaccination histories. Children have a "missed opportunity" for MCV if they were not up-to-date and if there were dates on which other vaccines were administered but not MCV. The "highest achievable" MCV vaccination coverage rate is 100% minus the sum of the percentages of (i) undervaccinated children with parents who requested an exemption; and (ii) undervaccinated children with parents who did not request an exemption and whose vaccination statuses were assessed during a kindergarten grace period or period when they were provisionally enrolled in kindergarten. RESULTS: Among all children undervaccinated for MCV, 2.7% were attributable to having a parent who requested an exemption. Among children who were undervaccinated for MCV and whose parent did not request an exemption, 41.6% had a missed opportunity for MCV. The highest achievable MCV coverage was 98.6%, actual MCV coverage was 90.9%, and the kindergarten vaccination gap was 7.7%. CONCLUSION: Vaccination coverage may be increased by schools fully implementing state kindergarten vaccination laws, and by providers assessing children's vaccination status at every clinic visit, and administering missed vaccine doses. |
Vaccination coverage among children in kindergarten - United States, 2015-16 school year
Seither R , Calhoun K , Mellerson J , Knighton CL , Street E , Dietz V , Underwood JM . MMWR Morb Mortal Wkly Rep 2016 65 (39) 1057-1064 State-mandated vaccination requirements for school entry protect children and communities against vaccine-preventable diseases. Each school year, federally funded immunization programs (e.g., states, territories, jurisdictions) collect and report kindergarten vaccination data to CDC. This report describes vaccination coverage estimates in all 50 states and the District of Columbia (DC), and the estimated number of kindergartners with at least one vaccine exemption in 47 states and DC, during the 2015-16 school year. Median vaccination coverage was 94.6% for 2 doses of measles, mumps and rubella vaccine (MMR); 94.2% for diphtheria, tetanus, and acellular pertussis vaccine (DTaP); and 94.3% for 2 doses of varicella vaccine. MMR coverage increased in 32 states during the last year, and 22 states reported coverage ≥95%. A total of 45 states and DC had either a grace period allowing students to attend school before providing documentation of vaccination or provisional enrollment that allows undervaccinated students to attend school while completing a catch-up schedule. Among the 23 states that were able to voluntarily report state-level data on grace period or provisional enrollment to CDC, a median of 2.0% of kindergartners were not documented as completely vaccinated and were attending school within a grace period or were provisionally enrolled. The median percentage of kindergartners with an exemption from one or more vaccinations was 1.9%. State and local immunization programs, in cooperation with schools, can improve vaccination coverage by ensuring that all kindergartners are vaccinated during the grace period or provisional enrollment. |
Vaccination coverage among children in kindergarten - United States, 2014-15 school year
Seither R , Calhoun K , Knighton CL , Mellerson J , Meador S , Tippins A , Greby SM , Dietz V . MMWR Morb Mortal Wkly Rep 2015 64 (33) 897-904 State and local jurisdictions require children to be vaccinated before starting school to maintain high vaccination coverage and protect schoolchildren from vaccine-preventable diseases. State vaccination requirements, which include school vaccination and exemption laws and health department regulations, permit medical exemptions for students with a medical contraindication to receiving a vaccine or vaccine component and may allow nonmedical exemptions for religious reasons or philosophic beliefs. To monitor state and national vaccination coverage and exemption levels among children attending kindergarten, CDC analyzes school vaccination data collected by federally funded state, local, and territorial immunization programs. This report describes vaccination coverage estimates in 49 states and the District of Columbia (DC) and vaccination exemption estimates in 46 states and DC that reported the number of children with at least one exemption among kindergartners during the 2014-15 school year. Median vaccination coverage* was 94.0% for 2 doses of measles, mumps, and rubella (MMR) vaccine; 94.2% for the local requirements for diphtheria, tetanus, and acellular pertussis vaccine (DTaP); and 93.6% for 2 doses of varicella vaccine among the 39 states and DC with a 2-dose requirement. The median percentage of any exemptionsdagger was 1.7%. Although statewide vaccination coverage among kindergartners was high during the 2014-15 school year, geographic pockets of low vaccination coverage and high exemption levels can place children at risk for vaccine-preventable diseases. Appropriate school vaccination coverage assessments can help immunization programs identify clusters of low coverage and develop partnerships with schools and communities to ensure that children are protected from vaccine-preventable diseases. |
Vaccination coverage among children in kindergarten - United States, 2013-14 school year
Seither R , Masalovich S , Knighton CL , Mellerson J , Singleton JA , Greby SM . MMWR Morb Mortal Wkly Rep 2014 63 (41) 913-20 State and local vaccination requirements for school entry are implemented to maintain high vaccination coverage and protect schoolchildren from vaccine-preventable diseases. Each year, to assess state and national vaccination coverage and exemption levels among kindergartners, CDC analyzes school vaccination data collected by federally funded state, local, and territorial immunization programs. This report describes vaccination coverage in 49 states and the District of Columbia (DC) and vaccination exemption rates in 46 states and DC for children enrolled in kindergarten during the 2013-14 school year. Median vaccination coverage was 94.7% for 2 doses of measles, mumps, and rubella (MMR) vaccine; 95.0% for varying local requirements for diphtheria, tetanus toxoid, and acellular pertussis (DTaP) vaccine; and 93.3% for 2 doses of varicella vaccine among those states with a 2-dose requirement. The median total exemption rate was 1.8%. High exemption levels and suboptimal vaccination coverage leave children vulnerable to vaccine-preventable diseases. Although vaccination coverage among kindergartners for the majority of reporting states was at or near the 95% national Healthy People 2020 targets for 4 doses of DTaP, 2 doses of MMR, and 2 doses of varicella vaccine, low vaccination coverage and high exemption levels can cluster within communities. Immunization programs might have access to school vaccination coverage and exemption rates at a local level for counties, school districts, or schools that can identify areas where children are more vulnerable to vaccine-preventable diseases. Health promotion efforts in these local areas can be used to help parents understand the risks for vaccine-preventable diseases and the protection that vaccinations provide to their children. |
