"People who get vaccinated only against Lyme disease might relax their vigilance against ticks and become more vulnerable to these other tick-borne illnesses, which are rapidly emerging in several parts of the United States. Progress has been made in developing vaccines that cause our immune systems to attack the tick itself when it attempts to feed. Indeed, some breeds of cattle, and some humans, are resistant to tick bites because of inherent immunity to proteins in tick saliva. "
