Insights

Vaccination coverage for homeless children in Washington D.C. is significantly lower than for other children, including those in poverty. This highlights a critical need for targeted vaccination programs for this vulnerable population.

Area of Science:

  • Pediatrics
  • Public Health
  • Epidemiology

Background:

  • Comprehensive vaccination coverage among homeless children in the U.S. is largely unknown.
  • Previous studies suggest low coverage with single vaccinations in this population.

Purpose of the Study:

  • To compare the vaccination coverage of a combined 7-vaccine series among homeless children in Washington D.C. (DC) to other U.S. children.
  • To assess the risk of under-vaccination in children experiencing homelessness.

Main Methods:

  • A cross-sectional survey of 135 homeless children aged 19-35 months in DC from 2018-2019.
  • Vaccination records were obtained from healthcare providers.
  • Coverage was compared to the 2018 National Immunization Survey (NIS) data for DC children, U.S. children, and U.S. children in poverty.

Main Results:

  • Only 52.6% of homeless children in DC were up to date on their 7-vaccine series.
  • This coverage was significantly lower (11.5-20.4 percentage points) than national estimates for all U.S. children, DC children, and children in poverty.
  • Even after adjusting for age and race/ethnicity, DC homeless children had lower coverage than U.S. children in poverty.

Conclusions:

  • Children experiencing homelessness are at heightened risk of under-vaccination compared to children in poverty.
  • Targeted vaccination delivery support is crucial for children experiencing homelessness.
  • Increased awareness of this risk can inform public health interventions.

Specialized Care Centers and Settings-II

Rural Health Centers
Rural health centers are specialized care facilities in remote locations with very few medical personnel. The primary care providers who run the centers are mostly Registered Nurse Practitioners. Here, emergency treatment is provided to critically ill or injured patients before they are transferred to the closest hospital. Fortunately, due to advancement in technology, many rural healthcare facilities and professionals have easy access to diagnostic and treatment...

Immunodeficiency Diseases01:25

Immunodeficiency Diseases

Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency...

Bias in Epidemiological Studies

Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

Development of Immunocompetence01:22

Development of Immunocompetence

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...

Prevalence and Incidence01:08

Prevalence and Incidence

In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...
