How does passive immunity work - what is the point if there are no memory cells? Also, is herd immunity a type of this?

[AG-qlsy]

hello:), at 2:06 under natural immunity it says creation of the bodies own antibodies, is that only possible from plasma cells directly or can antibodies magically appear from somewhere other than plasma cells?

[reece]

when talking about how vaccination leads to immunity, do you not have to mention the role of helper T cells?

Hi Miss, your slide says that A pathogen doesn’t enter the body so plasma cells are memory cells are not made, so if no pathogen enters what is the need for antibodies?

[lilac_turnip]

Hi miss, why do "disease diagnosis occur by testing for the presence of specific pathogen antibodies in the blood" instead of testing for antigens?
