The vaccine has been deemed safe for pregnant women. To protect their infants, most pregnant women who were not previously vaccinated with Tdap should get one dose of Tdap during the late second trimester or third trimester of pregnancy . The CDC recommends that women get the Tdap vaccine during each pregnancy. If not administered during pregnancy, women should get the vaccine postpartum before leaving the hospital or birthing center. Getting vaccinated with Tdap is especially important for mothers and families with new infants as well as all people caring for newborns. When a woman receives the Tdap vaccine during pregnancy, the antibodies she develops to the Bordetella pertussis bacterium are transferred to the infant, providing some additional protection to the infant before the baby can be fully vaccinated.
Sometimes, food is not completely broken down in the stomach or small intestine. There are a variety of reasons why food does not break down in the stomach or small intestine including lactose intolerance (the body lacks the enzyme lactase to break down lactose), for example. Once the food arrives in the large intestine, there are hundreds of bacteria (normal flora) that are available to help break down break down the undigested food. When this happens, a variety of gasses are released (much like the carbon dioxide released by yeast when making bread rise). These bacteria release gases like methane, hydrogen, and hydrogen sulfide. Hydrogen sulfide is the gas that causes odor.
As a demon, Dean's soul became twisted and he no longer empathized with others. He cared only for himself and what he needed. His change was so drastic that he stalked Sam throughout the Bunker with the intent of killing him using a hammer, only to miss by a few inches. He carried out this task calmly, and coupled it with taunts, giving the impression that he was enjoying himself. This is furthered by the fact that instead of an axe, he decides to use a hammer to break through a door and kill Sam, despite both tasks requiring much more force with a hammer than with an axe. Demon!Dean apparently cared about the natural order , something old Dean despised. He even considered himself, as a demon, a part of the natural order, and that it was all set up in this certain way.
