Lyme disease is the most commonly reported tick-borne illness in the U.S. Depending on the stage of infection, it can cause a wide range of symptoms, ranging from a fever and rash to neurological problems. "You can protect your dog in the U.S. against Lyme disease, but you can’t protect you or your children with a vaccine," says Dr. Gregory Poland, director of the Mayo Clinic Vaccine Research Group. https://mayocl.in/2pixQna | Mayo Clinic
