Immunity is a natural process, where your body learns to protect itself from attacks by bacteria, virus etc. This learning process takes some time. It's relation to age is that as you grow older you get better immunity due to prior exposure. It is not the clan that decides immunity though we find certain clans better equipped to fight diseases because they have been living in an endemic area for that disease. Immunity has more to do with the geographical region in which one lives rather than clan.
