Vaccines carry risk. Not vaccinating carries risk in that you leave yourself more vulnerable to VPD and their complications. 1 in 1000 people who get measles die. More than that get serious complications like encephalitis or pneumonia.
I respect peoples choice not to vaccinate if they decide that's whats best for them and their family, but saying there's no risk or consequence of that decision, or even that the risk is just "potential," is lying to yourself.
