evidence: The one thing that does concern me most is how babies with the mutation have a more difficult time processing and detoxing the harmful ingredients in vaccines. My son is due for his 4 month vaccinations on Wednesday. Before he received his 2 month shots, I asked if he could receive the 4 vaccines in two appointments about a week apart; they wouldn't allow it. He had a rough 24 hours after his shots -- sore legs and fever -- and I just prayed and prayed that the vaccines would only protect and not harm him. Thanks for your post. MTHFR was almost constantly on my mind at some point, and I had almost forgotten about it. I would have never thought that some of the marks on my baby's body could be indicators of the mutation. If you and your baby can get tested, I believe you should. [...] My baby girl has the dimple and blue vein, are those really indicators? We were concerned about vaccines for other reasons, but I DO know that kids with this mutation have a harder time ridding toxins from their bodies. DH and I are pretty sure his niece has averse reactions to vaccines so once I found out about these indicators to the gene mutation I let out a sigh of relief. I think she may have the gene.
