If there is no immunity from prior infection, then there is no immunity from any of the vaccines.
A vaccine is a stripped-down version of some sort of immune stimulus that point's the body's defenses in the same direction as a genuine infection. These vaccines are supposed to focus on only part of the virus structure, while a natural immune response would cover the whole virus.
Normal vaccines are gimped virii. mRNA vaccines hijack your cellular machinery to produce virus parts that hopefully train your immune system to recognize the real virus.
