If someone has developed antibodies (such as IgA), could these be transferred from one human to another through kissing (with tongues)? I am looking at a theory that kissing has an adaptive function, and that females are gaining something from the male saliva. Males have been found to have a higher level of IgA in their saliva (the antibody for HPV, which leads to cervical cancer). I was wondering whether it is faesable for an antibody to be transferred simply by kissing, and if so, how long it would take for that to be absorbed into someone's immune system?
