Original Title: Can it cause problems that you develop antibodies for a virus, but then that virus evolves? So later when you catch it again, your body tries to fight it with the same antibodies that are only partially effective?

Can someone who knows something about this topic tell me if this is possible or not? That the body recognises the same virus, but the antibodies are only partially effective, so the body has a tough time dealing with the rest of it?
