The Texas County Retrospective Immunization School Survey (TCRISS) methodology was developed to fulfill a need for county specific vaccination coverage level estimates. This survey was designed to retrospectively assess the vaccination coverage levels of public school kindergarteners when they were 24 months of age (approximately three years prior to the survey date). The survey design is dependent on the population size of kindergartners in the county and the number of kindergarten schools. For counties with smaller populations, it may be necessary to include all kindergarten students in the survey. For medium and large counties, a sample of kindergarten students is taken.
Vaccination coverage with the 4:3:1 vaccine series (4 doses of diphtheria-tetanus-pertussis vaccine, 3 doses of polio vaccine, 1 dose of measles-mumps-rubella vaccine), the 4:3:1:3:3 vaccine series (4 doses of diphtheria-tetanus-pertussis vaccine, 3 doses of polio vaccine, 1 dose of measles-mumps-rubella vaccine, 3 doses of Haemophilus influenzae type b vaccine, 3 doses of hepatitis B vaccine), and coverage with each individual vaccine will be assessed when the children were 24 months of age.
