Invalid Vaccine Doses Among Children Aged 0 to 35 Months: 2011 to 2020.

Background And Objectives: Vaccine doses provided outside the Advisory Committee on Immunization Practices for minimum and maximum ages of vaccination and minimum intervals between doses are considered invalid. Our objective was to quantify the prevalence of and factors associated with invalid doses among US children aged 0 to 35 months.

Methods: We analyzed provider-verified vaccination records from the nationally representative 2011-2020 National Immunization Survey-Child.

Influences on COVID-19 vaccine Decision-Making: A Qualitative Study With Urban Indigenous and Rural Adults.

Despite the safety and effectiveness of the COVID-19 vaccine, public hesitancy about receiving vaccination remains strong among disproportionately affected populations in the United States. To design more locally and culturally appropriate strategies, research is needed to explore the qualitative characteristics of vaccine hesitancy in these populations. Thus, we conducted in-depth interviews with 19 Indigenous and 20 rural participants and utilized a grounded theory approach to identify factors associated with their COVID-19 vaccine decision making.

National trends in patterns of under-vaccination in early childhood: National Immunization Survey-Child, United States, 2011-2021.

Background: The study's objective was to examine national trends in patterns of under-vaccination in the United States.

Research Design And Methods: The National Immunization Survey-Child (NIS-Child) is an annual cross-sectional survey that collects provider-verified vaccination records from a large national probability sample of children. Records from the 2011-2021 NIS-Child were used to assess receipt of the combined 7-vaccine series by age 24 months.

Vaccination Timeliness Among US Children Aged 0-19 Months, National Immunization Survey-Child 2011-2021.

Importance: Delays in receiving vaccinations lead to greater vaccine-preventable disease risk. Timeliness of receipt of recommended vaccinations is not routinely tracked in the US, either overall or for populations that have known barriers to accessing routine health care, including lower-income families and children.

Objective: To measure vaccination timeliness among US children aged 0 to 19 months, overall and by socioeconomic indicators.

Systematic Review of Barriers to and Facilitators of Screening for Postpartum Depression at Well-Child Visits in the United States.

Objective: To identify and evaluate barriers to and facilitators of screening for postpartum depression (PPD) during well-child visits in the United States. Additionally, to describe prior work on PPD screening tool evaluation and outcomes from PPD screenings conducted within the well-child setting.

Data Sources: A systematic review was conducted following Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines.
