Is the vitamin K shot safe?

The vitamin K shot, recommended for newborns by the CDC, the American Academy of Pediatrics, and actual doctors (read: not quacks), is not only safe but it can actually save infant lives. Vitamin K is essential for blood clotting, and lack of it can lead to very rare yet very dangerous bleeding disorders. 
Nevertheless, a disturbingly increasing number of parents, who have final say on whether their infants get the shot, are being misled by irresponsible blogs and chat groups which make scientifically unsupported claims, for instance that the shot is unnecessary at best, and unnatural and toxic at worst.
The truth is that vitamin K is naturally produced in the human body by the bacteria living in the gastrointestional tract. The problem is that newborns have a sterile gut and can’t produce enough vitamin K by themselves. Therefore, in order to render blood able to clot, and prevent bleeding problems, babies need a vitamin K boost, and that’s all that the shot is. Moreover, the shot has no side effects other than at a little sting at the injection site, which is certainly a small price to pay to avoid being diagnosed with vitamin K deficiency bleeding, just like four babies at a children's hospital in Nashville whose parents refused the shot.
By the way, we’re well aware of the irony of using a medium in order to decry something else that can be found on that very same medium, but please bear with us. It takes years of study and hard work to become a certified doctor, but it only takes a few minutes to set up a blog that’s nothing more than graffiti with punctuation, and even less time to become a parent. In those three instances, only the doctor is an expert, so if you’re going to listen to someone, listen to him. 
Many parents decline the vitamin K shot because they think it is vaccine, which it isn’t, and even if it was, there would still be nothing wrong with it. The point is that that’s an example of the confusion and misinformation that’s been running rampant regarding the vitamin K shot. So when you do your research, consider only authoritative sources, go to the library, talk to a professional physician, get a second opinion, and think of what’s best for the child.
