What are some of the careers in healthcare that most people do not know?

I am a college student majoring in Biology, Health, and Human Sciences. I initially planned to attend medical school to become a physician during my freshman year. However, in my last semester of sophomore year, things changed. I donʻt want to go to medical school anymore or become a physician. However, I know I still want to work in the healthcare field. What are some of the careers in healthcare that I can apply to after I graduate? Or Jobs in healthcare that needed additional certification after graduation?

Thank you for your help
