If a person A takes first dose of covid 19 vaccination and donates blood to another person B, will it be sufficient for B to take only second dose of covid 19 vaccination ? Or how it will influence the immunity of B?

The mRNA vaccines do not contain any blood products, including red blood cells, white blood cells or platelets. We will not know about the ingredients of other vaccines until each is submitted for approval, as companies are required to share this type of information.
Vaccines are currently the only way to limit the infection. But there are too many negative opinions against vaccines. Even people without primary education express opinions (negative), people who do not understand anything but are "against". False "facts" are written. This prevents all of humanity from solving this serious problem.
Most antisera including convalescent plasma is a conc source of antibodies.
Covid vaccine is protective by generating both tcell and bcell response.
Thus, this question should not arise. All have to to take the complete course of vaccine.
I agree with Pranav Ish, as this would just be a passive trasfer of antibodies, not the stimulation of B and T cells to produce abs/cellular immunity. Two vaccinations will definitely be required.

If the side effects are resolved in less than 4 weeks, donors must still wait for 4 weeks after vaccination before they can donate blood.
