Variability in Prevalence Estimates of Disability Among Children in the National Survey of Children’s Health

Abstract

administered for the same age groups was 16 146 (1648), 1330 (408), and 1529 (623), respectively.This equates to a drop in mean immunization rate between time periods of 31% for individuals aged 0 to 2 years, 78% for those aged 3 to 9 years, and 82% for those aged 10 to 17 years.All age groups had a significant drop in immunizations immediately following social distance guidance release (March 15, 2020).In individuals aged 0 to 2 years, the rate of immunizations dropped by 4581 (95% CI, 2965-6196) immunizations per week (P<.001).In individuals aged 3 to 9 years, it dropped by 2486 (95% CI, 568-4408) immunizations per week (P > .99),and in individuals aged 10 to 17 years, it dropped by 4060 (95% CI, 2156-5965) immunizations per week (P<.001)(Figure 1).While the pre-social distancing trend was declining by 405 (95% CI, 203-607) immunizations per week, the post-social distancing trends were not significant for all age categories.Trends were similar for Haemophilus influenzae type b; 13-valent pneumococcal conjugate; and measles, mumps and rubella vaccines (Figure 2).Discussion | Since the onset of the COVID-19 pandemic, vaccination uptake in children and adolescents has shown a significant decrease in Colorado.While the clinical implications of our observation are not yet known, public health advocates should consider addressing this drop to avoid the potential for vaccine-preventable diseases.Primary care professionals should consider implementing reminders and recalls to parents, 3 and local and state health departments should consider implementing immunization registry-based recall.4 Limitations of this report include its ecological nature, being limited to a single state, and the potential for missing data.
