Some vaccines use target antigen production instead of the actual virus itself. This can be accomplished in a number of ways such as the bait and switch of using a specialized strain of a similar virus or by using a target antigen carrier to provide it. In the case of measles, Hemagglutinin protein is the target antigen.
