People act like the vaccines are only saline solution with a bit of dead virus. They act as though preventing measles or rotavirus or chickenpox is so important that we should never, ever question what we might be getting in place of that illness. Somehow to them life-long auto-immune conditions like arthritis, asthma and skin disorders and deadly food allergies (ie peanuts) are better than having a rash and a fever for a week. They are so afraid of dying from chickenpox that they find it acceptable to live a life of poor health without vibrancy.
For me, I don't want to be so afraid of dying that I give up my quality of life. There are better and safer ways of coping with the fever and rash that comes with measles, mumps, rubella and chickenpox.
