Answer 1

Following a viral infection, what biological response(s) can occur?

The correct answer is All of the above. In this case, when a viral infection occurs, a bunch of cytokines produced of the innate immune system are released. This cytokines will promote a inflammatory process in the site of the infection, recruiting more cells of immunity defense and producing fever as a consequence of the inflammatory process.

Preventine vaccines are intended to protect

The correct answer is Organisms free of the targeted viral infection. In this type of vaccine, part of a virus or its inactive form is introduced into the organism to promote an immune system reaction and promoting the antibody production. This is mainly applied in people who is free of the targeted viral infection.
