It's good that you are at least thinking about it. There is nothing wrong with postponing the shots until you have done enough research and thinking about things to the point that you feel comfortable with whatever decision you make. You are right, there is always a chance that if you don't vaccinate your child may get one of the childhood diseases. That's why it is a good idea to learn about the diseases and find out which ones really are deadly much of the time. What it comes down to is how you personally perceive each disease and whether or not you believe it is more of a risk to vaccinate or not to vaccinate.
Some people selectively choose some vaccines and forego others.
It really is a personal decision. However, all states have some type of exemption and many are simply just signing a form, so in effect, no one really has to vaccinate if they disagree with it strongly enough. I can give you the law and exemptions in your state if you live in the US and can tell me where you live. I can also suggest where to find more info if you like. No Messages Hi.
