Lyme disease is an infectious disease caused by the bacterium Borrelia burgdorferi, which is transmitted to humans through the bite of infected black-legged ticks. Symptoms can include fever, headache, fatigue, and a characteristic skin rash, and if left untreated, it can lead to more severe health issues.
Vaccination is a medical procedure that involves administering a vaccine to stimulate the immune system to recognize and fight specific pathogens. It plays a crucial role in preventing infectious diseases and has been instrumental in controlling outbreaks and eradicating diseases like smallpox.
