National, state, and local area vaccination coverage among children aged 19-35 months --- United States, 2009

    Insights

    Childhood immunization coverage in 2009 showed increases for the hepatitis B (HepB) birth dose and hepatitis A (HepA) vaccine. Coverage for pneumococcal conjugate vaccine (PCV) remained stable, while rotavirus vaccine uptake was 43.9%.

    Area of Science:

    • Public Health
    • Epidemiology
    • Immunization Practices

    Background:

    • The National Immunization Survey (NIS) has monitored childhood immunization coverage since 1994.
    • Recent years have seen the introduction and recommendation of new vaccines for children.

    Purpose of the Study:

    • To report 2009 childhood immunization coverage estimates for children aged 19–35 months.
    • To focus on recently recommended vaccines: hepatitis B (HepB) birth dose, hepatitis A (HepA), pneumococcal conjugate vaccine (PCV), and rotavirus vaccine.

    Main Methods:

    • Analysis of data from the 2009 National Immunization Survey.
    • Estimation of vaccination coverage rates for children born between January 2006 and July 2008.

    Main Results:

    • Vaccination coverage increased for HepB birth dose (60.8%) and HepA (46.6%) in 2009 compared to 2008.
    • PCV (≥4 doses) coverage remained stable at 80.4%; rotavirus vaccine coverage was 43.9%.
    • Coverage for poliovirus, MMR, HepB, and varicella vaccines remained at or near 90%, with slight decreases for MMR and HepB.

    Conclusions:

    • Childhood vaccination coverage generally remained high in 2009, with increases in some newer vaccines.
    • The percentage of unvaccinated children remained low (<1%).
    • Vaccination efforts were maintained despite challenges like vaccine shortages and safety concerns.

    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...

    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 type of...

    Smallpox

    Smallpox is a severe contagious disease caused by the Variola major virus, a double-stranded DNA member of the Poxviridae family.Variola major transmission occurs primarily via inhalation of virus-laden droplets or direct contact with infectious scabs. The incubation period averages approximately seven days, although it may range from 7 to 17 days depending on the inoculum and host factors.Clinically, the prodromal phase is marked by an abrupt onset of high fever, malaise, headache, and myalgia.

    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.

    Poliomyelitis

    Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...
