It comes either in text form, or as a pdf file. The pdf file requires Adobe Acrobat, which is also available for free. The text version is just text--the pdf version has all the charts and tables. This is also the place for travel information. The "yellow book," as it is known in my office, is all there, and kept up to date. You can search by country, and get details about requirements and recommendations for travel anywhere. I use this in my office when patients are traveling. I'll get on the CDCs site, find the country, print the information out, and hand it to the parent/patient before they leave the office. Boy, are they ever impressed! Moshe Adler, MD
