Why is there such a wide variety of immune system responses between hosts when they are infected with the same virus?(1 point)
Responses
Slight variations due to mutations in the virus trigger different responses in people.

People that have already been infected are asymptomatic.

Some viruses are resistant to antibiotics, so they cause a stronger immune system response.

Each person’s immune system employs different tactics to get rid of the virus.
Explanation: Individuals differ in genetics (HLA, immune genes), prior exposure/vaccination, age, health and nutrition, microbiome, viral dose and co‑infections, all of which cause varied immune responses. (Other choices are incorrect: antibiotics don’t affect viruses; prior infection can reduce symptoms but doesn’t explain the general wide variation; small viral mutations aren’t the main reason for host-to-host differences.)
