The Majority of Vaccines Work by Eliciting Pathogen-Specific Antibodies That

The majority of vaccines work by eliciting pathogen-specific antibodies that circulate in our bodies and protect us in the event that we are later exposed to that specific pathogen. For most viruses and bacterial toxins that we are vaccinated against, these pre-existing antibodies are protective because:

A) They neutralize the virus or toxin, preventing it from attaching to and entering our cells.
B) They bind to the virus or toxin and carry it to the liver where it can be degraded.
C) They bind to the virus or toxin and directly induce lysis.
D) They induce mucus production that helps flush the toxin or virus out of the body.
E) They bind to epithelial cells and induce the production of antimicrobial peptides.
