This is the link to the website for my pediatric practice.
This is the website for the American Academy of Pediatrics.
This website was designed by the AAP as a parenting resource.
This is the Centers for Disease Control and Prevention (CDC) website.
The CDC immunization pages.
The Children's Hospital of Philadelphia website about immunizations. This is a comprehensive resource with detailed information about vaccines.
