The information in this site should not be regarded as medical advice. I am not a doctor; I am not trained, and do not have the expertise needed to provide medical advice. I am a parent who is trying to find out as much good, science-based information as I possibly can about vaccines and vaccine preventable diseases. This is a journey of discovery, and as such, it is possible that bad information might find its way in this site. Please, speak to your doctor about any questions you might have, and especially prior to making medical decisions.
