Close, but not entirely correct:

A vector in this context is any living carrier of a disease. In the case of Lyme's it would be an insect, but it could also be - for example - a domestic cat, which can pass toxoplasmosis to people via contact with cat faeces.

Quick correction, in the above comment it mentions that a vector for Lyme disease would be an insect - usually it is a tick which is not an insect but part of the spiders & mites family! The tick carries the bacteria from one host to another therefore becoming a vector for the disease.
