Summary:  View help for Summary This survey is part of a series that was designed to track the rates of proper vaccination of children in the United States. The target age range for the children was 19 to 35 months. Respondents were queried on the number of children present in the household between the ages of 12 months and 3 years, their dates of birth, their sex, whether there were vaccination records for the children, whether those records were accessible, whether the respondent was the adult in the household most knowledgeable about the vaccinations, and whether the respondent accompanied the children to more than 50 percent of their vaccinations. For each child in the household, information was gathered on whether each child had received all of the recommended vaccinations, and the number of the diphtheria-tetanus-pertussis shots (DTP or DT), polio vaccinations, measles vaccinations, meningitis or Haemophilus Influenzae type B (HIB) shots, varicella (chicken pox) vaccinations, rotavirus shots, pneumococcal shots, and hepatitis B (Hep B) shots each child had received. Further information was obtained about additional vaccinations the child may have received to combat diseases such as tuberculosis, typhoid, yellow fever, and malaria, the child's health care providers, the number of doctors that had performed vaccinations, and whether the measles vaccination was strictly for measles or for the measles-mumps-rubella (MMR) combination. Additional information was gathered regarding whether the child received benefits from the nutrition and health program for Woman, Infants, and Children (WIC), what age the child began receiving WIC benefits, whether the child's vaccination records were checked at the WIC certification visit, and whether these benefits had ever been interrupted for six months or more. Once parental consent was obtained, health care providers were queried on the vaccination records for each child whose vaccination information was gathered from parents. Health care providers were queried on the type and the level of detail of the vaccination records for each child, the dates and types of vaccinations administered, the date of each child's first visit to that provider regardless of reason, the date of the child's most recent visit to that provider regardless of reason, and the type of care the provider gave to the child. Health care provider respondents were asked to describe their facility, to give their position within the facility, the child's date of birth, according to their records, and whether the child was known by another last name, and to provide a list of any additional health care providers for that child. Demographic information provided by the parents or guardians includes the number of people living in the household, the number of people over and under 18 in the household, respectively, the number of children under the age of 12 months, ethnicity of respondent and child, marital status of the respondent, respondent's relationship to the child, respondent's educational level or that of the child's mother, the date of birth of the child's mother, household income, and whether the child was living at the same address as when he or she was born.

Weights:  View help for Weights Includes two weights - WGT_RDD (Final household interview weight for child.  Use this weight for estimates based on children with completed household interviews) and WGT (Final child weight to use for the calculation of vaccination coverage rates for children with adequate provider data). Both weights are calculated to 5 decimal places.
