A pathogen is an agent that causes disease, such as a virus, bacterium, protozoan, or parasite.
A vector is an organism, often an arthropod, that carries a pathogen to its host.
So, for example, for malaria the pathogen is a protozoan called Plasmodium, and the vector is a mosquito callef Anopheles. For plague, the pathogen is a bacterium called Yersinia pestisand the vector is a rat flea, Xenopsylla cheopis.
