Question

An 11-year-old male has rhinorrhea, nasal congestion, and low-grade fever consistent with a viral upper respiratory infection (URI). This is the 2nd URI he has had in the past year. In this situation, the main role of specific antibodies against a virus is: A. Elimination of the primary or initial infection of cells via complement B. Neutralization of viral peptides and prevention of reinfection C. Inhibition of immune complexes involving viral peptides D. Clearance of virus from infected cells via phagocytosis E. Degranulation of mast cells

Explanation / Answer

Q: An 11 year old male has rhinorrhea, nasal congestion, and low grade fever consistent with a viral upper respiratory infection (URI). This is the 2nd URI he has had in the past year. In this situation, the main role of specific antibodies against a virus is:

A) Elimination of the primary or initial infection of cells via complement

B) Neutralization of viral peptides and prevention of reinfection - Correct Answer (Antibodies that were produced during the primary immune response will protect against the reinfection by neutralization of viral peptides and opsonization)

C) Inhibition of immune complexes involving viral peptides

D) Clearance of virus from infected cells via phagocytosis

E) Degranuation of mast cells.
