- ≥1 Td or Tdap refers to 1 or more doses of tetanus toxoid-diptheria vaccine (Td) or tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) since the age of ten years.
- ≥1 Tdap refers to 1 or more doses of tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) since the age of ten years.
- ≥1 MenACWY refers to 1 or more doses of the meningococcal conjugate vaccine (MenACWY) or meningococcal-unknown type vaccine.
- ≥1 HPV refers to 1 or more doses of the quadrivalent or bivalent human papillomavirus vaccine. HPV coverage estimates are reported separately for females and males.
- ≥2 HPV refers to 2 or more doses of the quadrivalent or bivalent human papillomavirus vaccine. HPV coverage estimates are reported separately for females and males.
- ≥3 HPV refers to 3 or more doses of the quadrivalent or bivalent human papillomavirus vaccine. HPV coverage estimates are reported separately for females and males.
- HPV 3 dose series completion refers to the percent of females or males who received three or more doses among those who had at least one HPV vaccine dose and at least 24 weeks between the first dose and the interview date.
- ≥2 MMR refers to 2 or more doses of measles-mumps-rubella vaccine.
- ≥3 HepB refers to 3 or more doses of hepatitis B vaccine.
- ≥1 VAR refers to 1 or more doses of varicella vaccine among those with no history of varicella disease by parental or provider report
- ≥2 VAR refers to 2 or more doses of varicella vaccine among those with no history of varicella disease by parental or provider report.
- Vaccination coverage estimates are presented as a point estimate (%) with a 95% confidence interval (95% CI). Confidence intervals around the coverage estimates are measures of precision; wide confidence intervals are a sign of a relatively small sample size and relatively less precision. Consequently, looking at an area's data over time is also valuable to a correct understanding of apparent changes in coverage. Where confidence intervals overlap, the observed difference might be due to chance.
- Cells indicating that estimate=NA (Not Available) reflect coverage estimates that do not meet the NCHS standard of reliability or precision: if the unweighted sample size for the numerator was less than 30 or (CI half width)/Estimate greater than 0.6. In these cases, the estimate for that subgroup is not reported, but the individuals are still included in the overall sample and may have an effect on the overall estimate. State estimates with (CI half width) greater than 10 may be unreliable, but are reported and marked by a footnote.
- Race was self-reported by the parent or guardian. Hispanic adolescents can be of any race. Native Hawaiian or other Pacific Islanders and persons of multiple races were not included because of small sample sizes.
- An area's vaccination coverage estimate is based on the provider-reported vaccination histories. Complex statistical methods are used to adjust for adolescents whose parents refuse to participate, those who live in households without telephones, or those whose immunization histories was not reported by their providers.
