Question

Please help with this question, please be specific

2. You are at a family dinner. Your cousin asks you if he should have his son vaccinated for varicella considering he had chicken pox last year. Confidently, you tell him: “No, you don't need to have him vaccinated for this specifically given that he already had chicken pox, meaning that he is now immunized. However, it is very important that children and adults are vaccinated according to the immunization schedule to prevent other contagious and life-threatening diseases.” a. Which physiological mechanism can justify your claim that your cousin's son is immunized against varicella? Explain the process in detail. b. Using layman terms, explain to your cousin the difference between active and passive immunization and their subcategories. Be creative! For example, feel free to use a dialogue format, and/or provide acronyms and/or metaphors (etc.).

Answer 1

A. Chickenpox virus can become latent within sensory nerves and may remain dormant for years and hence provides immunity .

Stress, aging, or immune suppression reactivates the viruses in 15-20% of individuals who have had chickenpox

Reactivated viruses travel down the nerve they inhabit and produce an extremely painful skin rash near the end of the nerve. This rash, known as shingles or herpes zoster, forms in the band of skin associated with the nerve or in the eye.

B. Difference between passive and active immunisation is that passive which comes freely while active needs energy and work

Active immunity :-

person's OWN body produce antibodies in response to presence of pathogen

Passive immunity :-

antibodies are GIVEN rather than produced by person's own body
