Immunization Coverage Levels
The DSHS Immunization Unit monitors vaccination coverage levels across the state of Texas. Coverage levels are derived from national data collected by the U.S. Centers for Disease Control and statewide surveys conducted in schools and child-care facilities. Please use the navigation menu on the left side of this page to see the latest results from various surveys, described below.
National Immunization Survey (NIS)
The NIS is a set of national surveys conducted annually by the Centers for Disease Control and Prevention to assess immunization levels. The NIS-Child assesses immunization coverage among pre-school children at 24 months of age. The NIS-Teen assesses immunization levels for adolescents 13-17 years of age. The NIS is the only population-based survey to provide national, state, local area, and territorial estimates of vaccination coverage among pre-school aged children and adolescents 13-17 years in the United States.
The NIS-Flu assesses influenza immunization coverage levels annually by combining data from other surveys including other NIS modules and the Behavioral Risk Factor Surveillance System. The NIS-Flu provides national, state, local area, and territorial estimates of influenza vaccination coverage among children and adults in the United States.
The Behavioral Risk Factor Surveillance System (BRFSS)
The BRFSS is a national survey conducted annually by the CDC to assess behavioral risk factors, including immunizations levels, for non-institutionalized U.S. adults. The BRFSS provides national, state, and regional estimates of vaccination coverage. The BRFSS includes questions from the CDC that are asked in all 50 states and questions that are state-generated and asked only in specific states. For several years, Texas has chosen to ask additional vaccination coverage questions that are not asked nationally.
The School Coverage webpage includes data from the DSHS Annual Report of Immunization Status. All public school districts and accredited private schools in Texas are required to complete the Annual Report of Immunization status each year. The annual report provides immunization coverage levels for required vaccines among students in Kindergarten and in 7th grade, as reported by the school/district. It also captures data on the number of conscientious and medical exemptions that are filed. It is important to note that children being home schooled or attending non-accredited private schools are not included in this report.
In accordance with Texas Administrative Code §97.62, Texas law allows for an exemption from immunizations for reasons of conscience, including a religious belief. To claim an exemption due to reasons of conscience, a student's parent or legal guardian must request, sign, and submit an official DSHS affidavit form to the child's school. The affidavit is valid for two years. This webpage contains data on the percentage of K-12 students by school district/accredited private school and by county that have an exemption on file with their school.
This survey is conducted annually to validate the results of the DSHS Annual Report of Immunization Status in Texas Schools. A random sample of public and private schools is selected for the survey each year. Local health department and DSHS staff review a random sample of immunization records from each selected school. Statewide vaccination coverage levels are available for Kindergarten and 7th grade students attending public and private schools in Texas.
This survey is conducted annually to evaluate various immunization practices and policies in Texas hospitals. It includes information on employee vaccination policies, practices for perinatal hepatitis B immunization, participation in the Texas Vaccines for Children program and the Texas Immunization Registry (ImmTrac2).
Other Data Sources
Texas Immunization Registry (ImmTrac2)
The Texas Immunization Registry (ImmTrac2) consolidates and stores immunization records from multiple sources in one centralized system, for Texans that have consented into the registry. With more than 164 million immunization records, ImmTrac2 is a major component of our initiative to increase vaccine coverage across Texas. Learn more about the Texas Immunization Registry. The following vaccination administration data is updated on the 15th of every month.
