Vaccipack (VP) is an app for you as a parent to help manage your child's (or children's) pre-teen vaccines. The app was designed for parents of 11-14 year olds. The app provides a simple and effective way of keeping track of your child(s) vaccinations as well as inspirational stories and a discussion forum. The app also offers up to date information on recommended and required vaccines. Nurses and physicians from the University of Pennsylvania and Children's Hospital of Philadelphia created the app. The stories are inspired by the real life experiences of how providers and parents work together to keep teens healthy. In the discussion forum you can post comments, questions, tips, or other experiences you may have about your teen's health. Here, you can receive comments from other users or health professionals or post responses to other users' questions.
