I refused the vaccines for my son at his 4 year well check visit. Until then we had vaxed on schedule as told by the doctor for both kids. Anyway, she talked with me about my concerns and when I mentioned the ingredients that were in the vaccines she started explaining and became even more confused. She said they no longer use vaccines with thermerosol and that the aborted fetal cells used to be in there but not anymore. She explained the importance of vaxing, but I am still not so sure.
