Vacunes TB/BCG

A newborn in Mexico is suppose to get this vaccine in the hospital when they are born. Apparently the private hospitals are bad about not doing this. So our baby got hers on June 23rd when she was 3 months old. I was very interested in this vaccine because its not one that we get anymore in the states. I asked if we had to get it and the answer was yes it is one of the required vaccines for a child to go to school. So we went to get it. My husbands mom showed up that morning and said shed like to go with me to help translate. I said ok and we headed to the Segudo around 12pm. We were told the shots don't begin till one but its a first come first serve type of thing so they told us to show up at noon. When you get there you hand over your babies vaccine card and it is put in a stack with everyone else who is there for vaccines. We waited a little under an hour which is about how long I always had to wait at the Dr. in the states. So this wasn't to bad. What blew me away was as we were walking in for our turn the nurse said only one adult could go in with the baby. My husbands mom explained that my Spanish was limited and that she needed to translate. They said no and that if we wanted she could go in with the baby. Well that got whopping no from me and I said I would be ok. Which I was, thankfully most Medical words are conjugates in Spanish. So I understood when they told me that we needed to come back for more vaccines AUG 3rd. They also explained that the TB shot should not cause any fever, pain or diarrhea. But that in a few weeks it would swell up. The injection is intradermal, which means right under the top layers of skin. If you have ever had a PPD test which tests for TB then you know what it is. They make a bleb or small bump under your skin with the medicine. After a few days the bleb turned into a knot and then disappeared and her arm looked normal. Then about a week ago it started with a small red bump that looked almost like a mosquito bite. Then it got larger and was a knot again. Because I never studied this vaccine in school nor have I ever seen one except the scar left behind I was constantly asking neighbors and family if it was looking like its suppose to. A few days ago we were at my husbands grandmas house and I asked again. The knot was about the size of a garbanzo bean and there was redness surrounding it. They said it was fine and to stop worrying. Yesterday I had her in the bath and the knot began to pus and lot of exudate came out. It was thick and yellow and there was quite a bit. I kinda freaked out and grabbed my husband to come look. He said yes this was normal. I pushed gently on the knot until it was done. We saw one of his aunts later in the evening and I confirmed with her that it was ok. She said yes also. Today the knot is smaller but still there and it has a white head where the puss came out. I'm assuming it will happen again when shes in the tub and the skin gets wet. I'm trying not to mess with it to much to minimize the scaring. I hope this ends up being helpful to any moms who will be having newborns here and getting there shots.
