Hi, I am so excited to have found your products! My moral dillema is over…I do have a question, though. I am traveling to India in a few weeks, and have already purchased Demal and Typo200. I would like a Hepatitis A preventative. Is the Hepatitis spray alone enough for Hepatitis A, or do I need the other that works with it? If you could respond that would be great. I am leaving soon, and need to get my chemically addicted friends off my back. Thanks, Alex almazzucca@yahoo.com
