Evidence shows that there are certain metals in some vaccines that people who have an allergy to metals can react, which can affect them neurologically. (i’m autistic myself and was affected by a vaccine. i hope this helps.)
I'm a bit confused. What are you asking exactly? Maybe I could help then...
When ignore a conflict : you make the conflict become deeper and deeper that could lead to vengeful feeling between you and that other person
When you confront a person : you may hurt that person's feeling during the confrontation and that both of you and that person could explode in uncontrollable rage
When mediate a conflict : one of the party may think that you took the other's side, which also could lead to uncontrollable anger
