Why is there such a wide variety of immune system responses between hosts when they are infected with the same virus? (1 point)
• Some viruses are resistant to antibiotics, so they cause a stronger immune system response.
• People that have already been infected are asymptomatic.
O Slight variations due to mutations in the virus trigger different responses in people.
• Each person's immune system employs different tactics to get rid of the virus.

Each person's immune system employs different tactics to get rid of the virus.

Individual variation (genetics, prior exposures/vaccination, age, health, HLA types, etc.) causes different immune responses; the other choices are incorrect or only partially relevant (antibiotics don't affect viruses; prior infection can make some asymptomatic; viral mutations can play a role but don't explain most host-to-host variation).
