I always heard that herpes was inside everyone but healthy immune systems suppressed outbreaks. I'm now hearing that the vaccine un-suppresses immune responses so it's basically a free for all for whatever wants to pop up.
There are some theories that everyone has cancer in them in microscopic amounts but most of the time the immune system keeps it in check. Cell division errors happen all the time but sometimes something happens that creates a cancer cell that the immune system doesn't recognize as foreign body and then manages to keep replicating until you have a tumor.
