CDC Panel Approves Changes to 2011 Immunization Schedule

The Centers for Disease Control and Prevention's (CDC's) Advisory Committee on Immunization Practices (ACIP) has approved numerous changes to the 2011 recommended schedule of immunizations for children.

The new CDC immunization chart for children will be published in the February 2011 issue of the CDC's Morbidity and Mortality Weekly Report(MMWR).

Recommended Changes for Children

The 2011 changes to the schedule for ages 0-6 years are as follows:

  1. revision of wording regarding a sidebar that states recommendations are for all children, with no exception for high-risk groups;

  2. added guidance on the hepatitis B vaccine schedule for children who did not receive a birth dose;

  3. added information on the use of 13-valent pneumococcal conjugate vaccine (PCV13); and

  4. guidance on administration of 1 or 2 doses of influenza vaccine based on the child's history of H1N1 influenza infection.

The rewording change pertains to a sidebar in the current schedule that says vaccines are "recommended for all children except certain high-risk groups." The words "except certain high-risk groups" were added in error and will be deleted from the 2011 child charts.

The second change is an addition of a hepatitis B footnote to the 2011 chart. That note will state that "infants who did not receive a birth dose should receive 3 doses of HepB on a schedule of 0, 1, and 6 months."

There was also a consolidation of the wording about the age for the last dose, which now will state "the final (3rd or 4th) dose in the HepB series should be administered no earlier than age 24 weeks."

The most substantial change is the addition of information on the use of PCV13. The new schedule reflects the recommendations listed in the September 3, 2010, issue of the MMWR and cover the supplemental dosing of PCV13 in children who have already received the PCV7 series.

The fourth change speaks to vaccination against influenza. The 2011 chart will include a new footnote that "children aged 6 months through 8 years who received no doses of monovalent 2009 H1N1 vaccine should receive 2 doses of 2010-2011 seasonal influenza vaccine."

For the 2011 chart, ages 7 through 18 years, the changes will be similar to the ones for the 0 through 6 years chart, but will also include the addition of the word "female" (already included in the adult chart) to the human papillomavirus (HPV) vaccine recommendation in the grid and also in footnote 2.

The panel voted unanimously to incorporate all changes for both the child and adult 2011 immunization schedules this week.
