Vaccinosis occurs when the dog's immune system is over-challenged, by either by too many vaccines at the same time, or if the dog's immune system is already revved up due to illness, injury, surgery, or a minor medical procedure and receives a vaccine or more on top of that. This can be accompanied by neurological symptoms which are usually treated with steroid injections. This can also develop into a severe disease state (GME/NME), in which the antibodies attack the dog itself. The treatment is steroids and chemotherapy.
Also common with vaccines, a bump can form and can abscess if left untreated. This happens when a piece of dirt or hair is picked up by the needle itself as it is pushed through the skin when giving a vaccine.

This article explains it better:

As in your puppy's situation, a high fever may immobilize the vaccines (kill them off) all together, so a titer on her may be wise, to see if these vaccines need to be repeated. Puppies need at least 2 vaccines (of each kind) in order to establish immunity after the age of 3 months.

Thanks so much for the link. It was very informative. It kinda freaked me out but it's good info to know.
