HealthDay News — The CDC has updated the 2015 childhood and adolescence immunization schedule. The agency followed recommendations made by the American Academy of Pediatrics and other medical organizations.

“The 2015 format is similar to last year and includes a single schedule for people birth through 18 years of age,” noted Carrie L. Byington, MD, of the AAP Committee on Infectious Diseases, and colleagues in a policy statement published in Pediatrics.

Although there wasn’t much change from the 2014 schedule, the AAP noted a few revisions, including new columns to stress the availability of inactivated influenza vaccine and live-attenuated vaccine starting at age 2 years, and the need for two doses of flu vaccine for some children aged 2 to 8 years. A double dose of the flu vaccine, however, is no longer needed in patients aged 9 to 10 years. A third column has been added in to reflect this change.

For young children aged 6 months to less than 12 months traveling outside the United States who need the measles, mumps, and rubella vaccine, a purple bar was added.

Minor clarifying word changes were made in the footnotes for diphtheria-tetanus-acellular pertussis and pneumococcal conjugate vaccines Extensive revisions were made to the meningococcal footnote to clarify appropriate dosing schedules for high-risk infants and children and for the use of different vaccines.
