Question

Imagine that you work for a state health department. Your supervisor has asked that you review vaccines for an upcoming training session for public health professionals. You will present this information in a professional report. For this report, you will select a vaccine-preventable disease or biological agent and describe the characteristics of a homeostatic system in both health and in a diseased state. Your report should include the pathophysiological impact on the body system affected in disease, how the disease functions in homeostasis, as well as a physiological explanation as to how the vaccine works.

Assignment Directions

The report should be on topic, original, and have clear foundations in evidence-based approaches. Assignments should be at least 3 pages double spaced, not including title page and references.

What happens during infection?

In a diseased person, when the bacteria or virus enters, immune system functions by producing antibodies, t and b lymphocytes. As a response to infection, body depletes nutrients and injures the cells and tissues of the body compromising the immune system.

How vaccine works?

Vaccine - it is a biological preparation which helps in developing immunity by imitating the disease causing infection. So the body considered it as antigen and start producing antibodies and t-lymphocytes without causing any illness to an individual. sometimes, it may produce mild symptoms such as fever. When the imitation infection gets over, the body retains the memmory of B and T- lymphocytes. so that body will know how to fight against the same disease in future.
