Insights

Childhood influenza vaccination coverage in the U.S. increased significantly from 2004 to 2012. However, by 2012, less than half of children received the flu vaccine, highlighting a need for improved vaccination rates.

Area of Science:

  • Public Health
  • Epidemiology
  • Vaccinology

Background:

  • Influenza poses a significant health risk to children.
  • Consistent influenza vaccination is crucial for pediatric health.
  • Monitoring vaccination coverage trends is essential for public health strategies.

Purpose of the Study:

  • To assess trends in U.S. childhood influenza vaccination coverage from 2004 to 2012.
  • To compare vaccination estimates between two major survey systems: NHIS and NIS-Flu.
  • To analyze coverage variations by health status, age, and race/ethnicity.

Main Methods:

  • Utilized data from the National Health Interview Survey (NHIS) and National Immunization Survey-Flu (NIS-Flu).
  • Estimated influenza vaccination receipt among children aged 6 months to 17 years via parental report.
  • Employed Kaplan-Meier survival analysis for estimate computation.

Main Results:

  • Overall childhood influenza vaccination coverage increased from 16.2% (2004-2005) to 47.1% (2011-2012) based on NHIS.
  • Children with high-risk health conditions showed higher vaccination rates.
  • Vaccination coverage decreased with increasing age; NIS-Flu provided slightly higher estimates than NHIS in later seasons.

Conclusions:

  • Childhood influenza vaccination coverage showed an upward trend but remained suboptimal by 2011-2012.
  • Significant gaps persist in achieving universal annual influenza vaccination for U.S. children.
  • Further efforts are required to ensure all children aged 6 months and older are vaccinated.

Influenza01:27

Influenza

Influenza is an acute, highly communicable viral disease that affects the respiratory tract and is responsible for seasonal epidemics worldwide. Influenza A is the most prevalent type associated with widespread outbreaks and is subtyped based on two surface glycoproteins: hemagglutinin (H) and neuraminidase (N), as in H1N1. These glycoproteins are essential for viral infectivity, transmission, and immune recognition. Transmission occurs primarily through respiratory droplets and contaminated...

Infectious Diseases and Their Occurrence01:28

Infectious Diseases and Their Occurrence

Infectious diseases appear in populations through various transmission patterns, influenced by pathogen characteristics, population immunity, environmental conditions, and social behavior. Understanding these patterns is essential for effective public health surveillance and intervention. These categories—sporadic, outbreak, epidemic, pandemic, and endemic—help frame the nature and scope of disease events.Sporadic diseases occur irregularly and infrequently, without a predictable...

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Vaccines01:21

Vaccines

Vaccines are among the most effective tools in preventive medicine, designed to prepare the immune system to recognize and combat infectious agents. By introducing antigens—substances that the immune system identifies as foreign—vaccines stimulate an adaptive immune response that leads to immunological memory. This immunological memory enables the body to mount a faster and more effective response upon future exposures to the actual pathogen.Vaccines can be categorized based on the...

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...
