so basically all pathogens have these things called antigens on them. they are the identification of the pathogen itself and a part of it that helps to spread the disease. so a dead or inactive cholera pathogen could be injected to your body through a syringe. this is your vaccine. this will cause immune system to create a response. your lymphocystes will start making anti bodies to kill the anigen in your body and memory cells so that when this pathogen effects your body again, your body can immediately react. this gives you active immunity against the pathogen- cholera

firstly, since cholera is mainly caused due to interaction with contaminated water sources, a vaccine is not required as just prevention from contaminated sources of water can be enough. however cholera vaccines are available.
