  1. Hi! Yes, you got it! The malaria vaccine I am making will contain small doses of malaria parasites that have been weakened, so that the immune system can easily defeat the parasites in the vaccine, and will be able to remember how to fight off malaria for real.

    Making weak parasites for the vaccine involves removing genes from malaria, the genes that cause disease and the genes that help the parasite survive. That way the vaccine parasites won’t be able to make people sick, and will train the immune system to kill off malaria in the future.
