You can tell someone that there have been 2,000 deaths in the US and 4,000 in the UK from vaccines and that the adverse effect figures are 40,000 and 160,000 respectively, but they will just say you're listening to conspiracy theorists, even if your information is from the CDC or its British equivalent. We can't put it on ourselves to make someone else see. We only have control of ourselves. And feeling guilty doesn't help. Just resist the hoax yourself and leave the other person in God's hands.
