    Insights

    Global vaccination efforts improved, but in 2012, 22.6 million children missed their third diphtheria-tetanus-pertussis (DTP) vaccine dose. Strengthening immunization programs is crucial to prevent diseases.

    Area of Science:

    • Public Health
    • Vaccinology
    • Global Health

    Background:

    • The World Health Organization's Expanded Programme on Immunization (EPI), established in 1974, aims for universal vaccine access.
    • Global coverage for the third diphtheria-tetanus-pertussis (DTP3) vaccine dose increased significantly from 5% in 1974 to 83% in 2011.
    • Despite progress, a substantial number of children remained unvaccinated, highlighting persistent global health challenges.

    Purpose of the Study:

    • To evaluate global progress towards the Global Vaccine Action Plan (GVAP) targets for DTP3 vaccine coverage by 2015.
    • To assess the extent of DTP3 vaccination coverage among infants worldwide in 2012.
    • To identify key areas for strengthening immunization systems to reduce vaccine-preventable diseases.

    Main Methods:

    • Analysis of global DTP3 vaccination coverage data for infants in 2012.
    • Assessment of national DTP3 coverage rates across 194 WHO member states.
    • Evaluation of district-level DTP3 coverage against GVAP targets (90% national, 80% district).

    Main Results:

    • In 2012, global DTP3 coverage was 83%, with significant regional variations.
    • 131 (68%) WHO member states achieved 90% national DTP3 coverage.
    • Only 59 (30%) member states met the target of 80% DTP3 coverage in every district, leaving 22.6 million children unvaccinated.

    Conclusions:

    • While global immunization coverage has improved, substantial gaps remain in achieving universal DTP3 vaccination.
    • The Global Vaccine Action Plan (GVAP) targets for 2015 were not met by many countries, particularly at the district level.
    • Strengthening national immunization systems, especially in high-burden countries, is a priority to reduce childhood morbidity and mortality from vaccine-preventable diseases.

    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...

    Preventive Healthcare Services

    Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:

    Vaccine Production01:23

    Vaccine Production

    Vaccine production involves a sequence of upstream and downstream processes to generate a safe and effective immunological product. It begins with cultivating microorganisms, such as viruses or bacteria, to obtain antigenic material. For viral vaccines, mammalian host cells are grown in bioreactors and subsequently infected with the target virus. The virus replicates within the host cells, which are lysed to release viral particles. This lysate is then clarified through filtration or...

    Principles of Disease Surveillance

    Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...

    Methods Of Healthcare Delivery System

    At the different levels of the healthcare system, we see varying methods of healthcare used. These methods include managed care systems, case management, and primary healthcare.
    Managed Care System:
    The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is...
