I have seen evidence that supports the statement that the vaccine causes miscarriages.
I have seen zero credible evidence that supports the statement that these particular coronavirus vaccines cause infertility (a long term effect). While such things can't be known without long term studies on the matter, I have seen no credible theories as to how that can happen (where "credible" means the source didn't also make mistakes in basic biology or understanding of the technologies of the vaccines).
