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.
DHS Immunization Unit (DSU) ni kitengo cha afya cha Marekani kinachofuatilia viwango vya chanjo katika jimbo la Texas. Kiwango cha chanjo ni inayotokana na takwimu za kitaifa zilizokusanywa na Vituo vya Marekani kwa ajili ya Udhibiti wa Magonjwa na tafiti ya jimbo nzima uliofanywa katika shule na vituo vya utunzaji wa watoto. Tafadhali tumia orodha ya urambazaji upande wa kushoto wa ukurasa huu kuona matokeo ya hivi karibuni kutoka kwa tafiti mbalimbali, zilizoelezwa hapa chini. Uchunguzi wa Kitaifa wa Chanjo (NIS) ni seti ya tafiti za kitaifa zinazofanywa kila mwaka na Vituo vya Kudhibiti na Kuzuia Magonjwa (CDC) ili kutathmini viwango vya chanjo. NIS-Child inathamini chanjo ya chanjo kati ya watoto wa kabla ya shule katika umri wa miezi 24. NIS-Teen inathamini viwango vya chanjo kwa vijana wa miaka 13-17. NIS ni utafiti pekee wa idadi ya watu kutoa kitaifa, jimbo, eneo la mitaa, na makadirio ya eneo la chanjo kati ya watoto wa kabla ya shule na vijana wa miaka 13-17 nchini Marekani. NIS-Flu inathamini viwango vya chanjo ya homa kila mwaka kwa kuchanganya data kutoka kwa tafiti zingine, pamoja na moduli zingine za NIS na Mfumo wa Ufuatiliaji wa Sababu za Hatari ya Utendaji. NIS-Flu hutoa makadirio ya kitaifa, ya jimbo, ya eneo la ndani, na ya kikanda ya chanjo ya mafua kati ya watoto na watu wazima nchini Marekani. Mfumo wa Ufuatiliaji wa Sababu za Hatari za Utendaji (BRFSS) ni utafiti wa kitaifa unaofanywa kila mwaka na CDC kutathmini sababu za hatari za tabia, pamoja na viwango vya chanjo, kwa watu wazima wa Amerika wasio na taasisi. BRFSS hutoa makadirio ya kitaifa, ya jimbo, na ya kikanda ya chanjo ya chanjo. BRFSS inajumuisha maswali kutoka kwa CDC ambayo yanaulizwa katika majimbo yote 50 na maswali ambayo hutengenezwa na jimbo na kuulizwa tu katika majimbo maalum. Kwa miaka kadhaa, Texas imechagua kuuliza maswali ya ziada ya chanjo ambayo hayaulizwi kitaifa. "Soma zaidi kuhusu ""School Coverage: Data kutoka kwa Ripoti ya Kila Mwaka ya DSHS ya Hali ya Chanjo.""" Shule zote za umma na shule za kibinafsi zilizoidhinishwa katika Texas zinahitajika kukamilisha Ripoti ya Mwaka ya Hali ya Chanjo kila mwaka. Ripoti ya kila mwaka hutoa viwango vya chanjo kwa chanjo zinazohitajika kati ya wanafunzi katika Kindergarten na darasa la saba, kama ilivyoripotiwa na shule au wilaya. Pia huchukua data juu ya idadi ya msamaha wa dhamiri na matibabu ambao umewasilishwa. Ni muhimu kutambua kwamba watoto ambao wanafundishwa nyumbani au kuhudhuria shule za kibinafsi zisizoidhinishwa hazijumuishwa katika ripoti hii. Kulingana na Kanuni ya Usimamizi ya Texas (§97.62) sheria ya Texas inaruhusu msamaha kutoka kwa chanjo kwa sababu za dhamiri, ikiwa ni pamoja na imani ya kidini. Ili kudai msamaha kwa sababu za dhamiri, mzazi au mlezi wa kisheria wa mwanafunzi lazima aombe, saini, na kuwasilisha fomu rasmi ya DSHS ya kiapo kwa shule ya mtoto. Taarifa hiyo ni halali kwa miaka miwili. Kwa mfano, orodha ya wanafunzi wa K-12 katika wilaya za shule na shule za kibinafsi zilizoidhinishwa na shule za kitaifa na shule za kibinafsi zilizoidhinishwa na shule za kitaifa. Uchunguzi huu unafanywa kila mwaka ili kuthibitisha matokeo ya Ripoti ya Mwaka ya DSHS ya Hali ya Chanjo katika Shule za Texas. Sampuli ya nasibu ya shule za umma na binafsi huchaguliwa kwa ajili ya uchunguzi kila mwaka. Idara ya Afya ya Mitaa na wafanyakazi wa DSHS hukagua sampuli ya nasibu ya rekodi za chanjo kutoka kila shule iliyochaguliwa. Viwango vya chanjo ya jimbo nzima vinapatikana kwa wanafunzi wa Kindergarten na darasa la saba wanaohudhuria shule za umma na za kibinafsi huko Texas. Uchunguzi huu hufanywa kila mwaka ili kutathmini mazoea na sera mbalimbali za chanjo katika hospitali za Texas. Mfumo huo unahusisha sera za chanjo za wafanyakazi, mazoea ya chanjo ya hepatitis B ya kuzaliwa, ushiriki katika programu ya chanjo ya watoto ya Texas na Usajili wa chanjo ya Texas (ImmTrac). "Kwenye orodha ya ""Kuchunguza Ugonjwa wa Texas"" (ImmTrac) ni orodha ya maambukizi ya Texas, ambayo inashughulikia maambukizi ya watu wote na kuhifadhi rekodi za chanjo kutoka vyanzo mbalimbali katika mfumo mmoja wa kati, kwa ajili ya watu wote wa Texas ambao wamekubali kuingia kwenye orodha." Kwa kuwa imepitisha rekodi za chanjo za milioni 164 za watu, ImmTrac2 ni sehemu muhimu ya mpango wetu wa kuongeza chanjo ya chanjo kote Texas. Jifunze zaidi kuhusu Texas Immunization Registry. Takwimu za chini za utoaji wa chanjo ni updated juu ya 15 ya kila mwezi.
