COVID-19 Vaccination Rates Among North Dakota Residents Who Gave Birth Between April 1, 2021, and July 15, 2022.

To assess COVID-19 vaccination rates among North Dakota residents who gave birth. We used data from North Dakota Vital Records and the North Dakota Immunization Information System for North Dakota residents who gave birth between April 1, 2021, and July 15, 2022. We evaluated vaccination with 1 dose, primary series, and monovalent booster for timing before and during pregnancy and postpartum.

Understanding Over-immunization in North Dakota's Adult Population.

Context: Over-immunization, or administration of excess doses of vaccine, is an understudied topic in immunization. Adult over-immunization is particularly understudied, so building a basic understanding of the sources and scope of over-immunization is necessary to direct action.

Objective: The aim of this evaluation was to quantify the extent of over-immunization in North Dakota's adult population from 2016 to 2021.

Influenza Vaccinations During the COVID-19 Pandemic - 11 U.S. Jurisdictions, September-December 2020.

Influenza causes considerable morbidity and mortality in the United States. Between 2010 and 2020, an estimated 9-41 million cases resulted in 140,000-710,000 hospitalizations and 12,000-52,000 deaths annually (1). As the United States enters the 2021-22 influenza season, the potential impact of influenza illnesses is of concern given that influenza season will again coincide with the ongoing COVID-19 pandemic, which could further strain overburdened health care systems.

Impact of the COVID-19 Pandemic on Administration of Selected Routine Childhood and Adolescent Vaccinations - 10 U.S. Jurisdictions, March-September 2020.

After the March 2020 declaration of the COVID-19 pandemic in the United States, an analysis of provider ordering data from the federally funded Vaccines for Children program found a substantial decrease in routine pediatric vaccine ordering (1), and data from New York City and Michigan indicated sharp declines in routine childhood vaccine administration in these areas (2,3). In November 2020, CDC interim guidance stated that routine vaccination of children and adolescents should remain an essential preventive service during the COVID-19 pandemic (4,5). To further understand the impact of the pandemic on routine childhood and adolescent vaccination, vaccine administration data during March-September 2020 from 10 U.

Comparing vaccination coverage of American Indian children with White children in North Dakota.

Objectives: The objective of this study was to compare immunization rates of American Indian (AI) and White children in North Dakota and identify disparities in immunization rates by race.

Study Design: The study design was to assess immunization coverage rates by race using immunization information system (IIS) data.

Methods: Data from the North Dakota Immunization Information System (NDIIS) for children aged 19-35 months during quarter four of 2014, 2015, 2016, 2017 and 2018 were used to assess and compare immunization coverage rates for AI and White children.

Using the North Dakota IIS to Assess the Response of Health Care Providers to the ACIP Recommendation for Tdap Vaccination During Pregnancy.

Objectives: To evaluate the response of North Dakota health care providers to follow the recommendation set forth by the Advisory Committee on Immunization Practices (ACIP) to administer a dose of tetanus, diphtheria, and acellular pertussis (Tdap) vaccine to women during each pregnancy using the North Dakota Immunization Information System (NDIIS).

Methods: Data from the NDIIS for North Dakota infants born during calendar years 2013-2018 were extracted. Mother's name was taken from the newborn records and matched to NDIIS female client records to identify the population of mothers of newborns who would have been recommended to receive Tdap during their pregnancy.

The impact of electronic health record (EHR) interoperability on immunization information system (IIS) data quality.

To evaluate the impact of electronic health record (EHR) interoperability on the quality of immunization data in the North Dakota Immunization Information System (NDIIS). NDIIS doses administered data was evaluated for completeness of the patient and dose-level core data elements for records that belong to interoperable and non-interoperable providers. Data was compared at three months prior to electronic health record (EHR) interoperability enhancement to data at three, six, nine and twelve months post-enhancement following the interoperability go live date.
