It brings immunization schedules divided into ages: from birth to 6 years, from 7 to 18 years old and another schedule to help children from 4 months to 18 years old who have missed any shots to get back on track. Documents are available colored, black and white, in different sizes and versions; all of them are in PDF format so Acrobat Reader is needed. It also has the MMWR schedule, changes made and related topics.
