how can common skin bacteria make people ill

I think  if you have bacteria and give that bacteria to a person that had never had that bacteria before and that person will get sick i hope i helped

If it gets into another part of the body where it's not supposed to be. So if you get a cut, the bacteria on your skin can travel to another part of the body and cause illness there by releasing toxins, rapidly multiplying, competing for nutrients, causing an immune response.

No matter what they say you can’t change who you are so when u tell them whatever they say jus be like i’m who i am and i won’t change

No, when getting the flu vaccine no drugs should be being takin at the time.
