Corrected footnote in immunization schedules. The Practice Guidelines “ACIP Releases 2013 Immunization Schedules” (February 1, 2013, p. 204) contained an error in footnote 13 of the recommended immunization schedule for persons aged 0 through 18 years and the catch-up immunization schedule for persons aged 4 months through 18 years who start late or who are more than 1 month behind. The third bullet point under “Routine vaccination” should read “For children aged 2 months through 10 years with high-risk conditions, see below” rather than “For children aged 9 months through 10 years with high-risk conditions, see below.” The online version of the immunization schedules has been corrected.
