Vaccines primarily aim to elicit an immune response, generating specific neutralizing antibodies that can prevent reinfection.

“vaccines and the goal of a vaccine for the most part is a b-cell strategy which is put in some form of attenuated inactivated virus or maybe just it's RNAi we'll come back to all the full means but you do something that elicits an immune response that is appropriate if we're lucky we not only get the appropriate immune response but it generates these specific antibodies called neutralizing antibodies those are the ones that matter”
