Peer review performs several important functions. I have been on the receiving end of it myself, with several papers I wrote, in the field of analytical chemistry.
It subjects submitted papers to scrutiny by experts in the same field, identifying flaws in methodology, data analysis, and interpretation.
It holds authors to high standards of research in their chosen field.
It filters out low quality, erroneous and unsubstantiated claims made by authors. It is rigorous. Probably why vaccine injury papers don't make the grade.
Your statements about peer review remind me of a dog howling at the moon.
