Correct. An attenuated virus, or partially inactivated virus, supplies the basic antigen, enough to elicit a primary immune response. When you are exposed to the actual, active virus, your body will immediately respond going into hyperdrive, manufacturing more antibodies within a short amount of time. You might get some symptoms, but your downtime is shorter and recovery quicker.

Which makes me wonder why cold viruses are so different. almost everyone has had a cold, so we definitely have the antibodies to fight it off. Of course, colds are either bad, terrible or sometimes you just have the sniffles a runny nose or a cough.
