@rred- Welcome to Mayo Clinic Connect. Your care team is all of the doctors you mention. At my hospital, it is my oncologist who "manages" everything. However, when I have a question that might be better answered by my lung surgeon or radiologist I email them directly. If I need something answered I go to the best source for an answer.

Now, you should have a PCP. Usually, if you need a vaccine it is the PCP who gives it to you or directs you to where you can get one. So far in my state, I haven't been notified as to when it will be available and where I go to have mine. Things are still very confusing and states are still receiving the vaccines. When I called my PCP to ask about mine I was told that they had no idea and recommended that I call my state health department. Well, of course, no one can get through. So for now I'm waiting for answers like everyone else.

Do you have a PCP?
