If the body creates antibodies in response to the vaccine, could you "vaccinate" others by donating blood ?

    Generally "convalescent plasma" therapy is more suited for treating active cases with antibodies taken from recovering cases. Lately it's seen occasional use with Ebola.

    For vaccinations, the idea is to give the body a mild infection so the immune system knows what to do with the germs when they come by for real, or in the case of the Covid vaccines, they teach your human cells how to make protein molecules that resemble part of the Covid virus.

    maybe

    either because there's vaccine in the donated blood, in which case the recipient makes antibodies

    or because the donated antibodies attack the virus/bacteria.

    The latter probably is shortlived, as antibodies don't live forever

    There is a therapy being used that injects plasma from people who have had the Chinese weaponized flu into people suffering from it.  So your idea in a sense is being used

    That is called passive immunity and not a vaccine. What the person vaccinated is donating is antibodies and those antibodies only last for a couple of months and then disappear. They don't last forever compared to a person who was actually vaccinated. Vaccination renders the person being vaccinated the ability to create antibodies on their own and in many cases lasts a lifetime. That is termed active immunization.

    Research on those lines, using blood plasma is in progress in UK.

    If you are currently infected, you would infect them.
