Vaccines

42
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...

Vaccine Production01:23

Vaccine Production

57
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...

Preventive Healthcare Services

2.3K
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:

Principles of Disease Surveillance01:26

Principles of Disease Surveillance

788
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

4.3K
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...

    Area of Science:

    • Public Health
    • Epidemiology
    • Global Health

    Background:

    • The World Health Organization’s Expanded Program on Immunization (WHO EPI) celebrated its 40th anniversary in 2014.
    • Since 1974, global vaccine coverage for four core vaccines (BCG, DTP, poliovirus, measles) has risen from under 5% to over 85%.

    Purpose of the Study:

    • To assess global immunization coverage rates for key vaccines in 2014.
    • To highlight the importance of routine immunization services and identify strategies for strengthening immunization programs.

    Main Methods:

    • Analysis of global immunization coverage data for 2014.
    • Assessment of coverage for DTP3, polio3, MCV1, and MCV2 vaccines.

    Main Results:

    • Estimated global DTP3 coverage was 86% in 2014, consistent with levels since 2009.
    • Estimated global MCV2 coverage was 38% by 24 months and 56% including older children, similar to 2013 levels.

    Conclusions:

    • Sustaining high immunization coverage requires effective vaccine stock management.
    • Leveraging opportunities like routine visits in the second year of life is crucial for strengthening immunization programs and reducing disease burden.
