alleryVaccination provides protection against future infection mainly by
Aweakening the pathogen on contact
Bcreating memory B and T cells specific to the pathogen
Cdestroying the body's antibodies
Dpreventing pathogens from entering the body
Answer & Solution
Correct answer: B. creating memory B and T cells specific to the pathogen

On real exposure, these memory cells trigger a fast, strong secondary response — usually clearing the pathogen before disease develops.
