Vaccination coverage of 2-year-old children--United States, 1991-1992
Insights
Monitoring childhood vaccination coverage is crucial for preventing diseases. The 1992 National Health Interview Survey provides updated vaccination estimates for two-year-olds, tracking changes from the previous year.
Area of Science:
- Pediatric Public Health
- Epidemiology
- Immunization Programs
Background:
- Childhood vaccination is a public health priority to prevent vaccine-preventable diseases.
- Most childhood vaccine doses are administered within the first two years of life, necessitating continuous coverage monitoring.
- National vaccination coverage estimates were not consistently available between 1986 and 1990.
Purpose of the Study:
- To present 1992 national vaccination coverage estimates for two-year-old children.
- To describe changes in vaccination coverage from 1991 to 1992.
- To inform public health strategies for childhood immunization.
Main Methods:
- Utilized data from the National Health Interview Survey (NHIS) conducted in 1991 and 1992.
- NHIS is a national survey of the civilian noninstitutionalized population.
- Calculated national estimates of vaccination coverage for children aged two years.
Main Results:
- Presents 1992 national vaccination coverage estimates for two-year-old children.
- Details the changes observed in vaccination coverage between 1991 and 1992.
- Highlights trends in childhood immunization rates.
Conclusions:
- Continuous monitoring of childhood vaccination coverage is essential for public health.
- The NHIS provides valuable data for tracking immunization rates in young children.
- Understanding coverage changes informs efforts to improve vaccine uptake and disease prevention.
Abstract:
Protecting children against vaccine-preventable diseases is a national priority in public health. Because approximately 80% of childhood vaccine doses are recommended for administration during the first 2 years of life, vaccination coverage among children must be continuously monitored. National estimates of vaccination coverage were calculated annually from 1959 through 1985 but not for 1986-1990. Beginning in 1991, national estimates of vaccination coverage of preschool children have been available through the National Health Interview Survey (NHIS), a national survey of the civilian noninstitutionalized population conducted by CDC's National Center for Health Statistics. This report presents 1992 national estimates of vaccination coverage for 2-year-old children and describes changes from 1991 to 1992.
