Adherence to Timely Vaccinations in the United States.
Abstract: To estimate 1) the proportion of children not adhering to the Advisory Committee on Immunization Practices (ACIP) recommended early childhood immunization schedule and 2) associations between schedule adherence, sociodemographic characteristics and up-to-date immunization status by 19-35 months of age. Methods: We used 2014 National Immunization Survey (NIS) provider-verified vaccination data to classify vaccination patterns as “recommended” (i.e., in line with ACIP dose- and agespecific recommendations), “alternate” (i.e., in line with either limiting the number of shots per visit or skipping at least one vaccine series) or “unknown/unclassifiable” (i.e., not in-line with ACIP recommendations nor clearly limiting shots per visit or vaccine series). We evaluated predictors of immunization schedule adherence patterns and estimated the association between vaccination patterns and up-to-date status for all ACIP-recommended vaccinations (including rotavirus and hepatitis A vaccines) using Poisson regression. Results: The majority of children’s patterns were classified as “recommended” (63%), with 23% and 14% following alternate or unknown/unclassifiable patterns, respectively; 58% of children were up-to-date with all ACIP-recommended immunizations by 19-35 months. Not being up-to-date was associated with alternate (prevalence ratio [PR] = 4.2, 95% confidence interval [CI] 3.9, 4.5) and unknown/unclassifiable (PR = 2.4, 95% CI 2.2, 2.7) vaccination patterns. Conclusion: Overall high vaccine coverage by 19-35 months of age may miss non-adherence to the recommended immunization schedule in the first 18 months of life, leaving children vulnerable to preventable diseases. With more than one-third of US children not following the ACIP schedule, targeted interventions are needed to minimize vaccine delays and disease susceptibility.
True or False: How Parents Decide to Seek, Vet, or Share Infectious Disease Outbreak Information
Accepted for presentation at the International Crisis and Risk Communication Conference (ICRCC), March 9-11, 2020, Orlando, FL. Abstract: Numerous studies have explored how publics seek and share crisis information, but none has examined whether publics verify the accuracy of crisis and risk information before sharing the information or seeking additional information. These considerations are especially […]
Integrating Strategy and Dosage: A New Conceptual Formula for Assessing Intended and Unintended Effects of Health Risk Communication
Accepted for presentation at the International Crisis and Risk Communication Conference (ICRCC), March 9-11, 2020, Orlando, FL. Abstract: How to detect side effects of repeated exposure of the same or similar campaign messages over time on at-risk publics has emerged as a critical research question currently understudied. By formulating a new way of assessing health […]
