2 Learning Objectives Provide the updates from 2017 Advisory Committee on Immunizations Practices (ACIP) pediatric vaccination and catch-up schedule Recommend best practices when administering vaccines to children and adolescents Demonstrate correct schedule recommendations for ACIP scheduled vaccines Interpret correct storage and handling of vaccines being administered

3 Disclosure Slide I have no relevant financial relationships with the manufacturer(s) of any commercial products(s) and/or provider(s) of commercial services discussed within this CME activity. I do NOT intend to discuss an unapproved or investigative use of a commercial product/device in my presentation.
