Data on vaccination coverage are used to identify groups at risk of vaccine-preventable diseases and to evaluate the effectiveness of programs designed to increase coverage. Rates of childhood and adolescent immunizations are one measure of how extensively children are protected from serious vaccine-preventable illnesses.
NOTE: The 4:3:1:3:3:1 series consists of 4 doses (or more) of diphtheria, tetanus toxoids, and pertussis (DTP) vaccines, diphtheria and tetanus toxoids (DT), or diphtheria, tetanus toxoids, and any acellular pertussis (DTaP) vaccines; 3 doses (or more) of poliovirus vaccines; 1 dose (or more) of any measles-containing vaccine; 3 doses (or more) of Haemophilus influenzae type b (Hib) vaccines; 3 doses (or more) of hepatitis B vaccines; and 1 dose (or more) of varicella vaccine. The recommended immunization schedule for children is available at http://www.cdc.gov/vaccines/schedules/index.html. In 2009, a Hib vaccine shortage affected the series estimate. The Advisory Committee on Immunization Practices (ACIP) recommended an interim suspension of the booster dose for healthy children. This was during the time when most children in the 2009 National Immunization Survey would have been eligible for the Hib vaccine booster dose.

NOTE: Data collection for 2006 and 2007 was only performed during the fourth quarter. Human papillomavirus (HPV) coverage level indicates females initiating the 3-dose series. Routinely recommended vaccines for administration beginning at ages 11–12 include tetanus-diphtheria-acellular pertussis (Tdap) and meningococcal conjugate (MenACWY) vaccines (both one dose), and HPV vaccine (3 doses). Since the routine recommendation for the administration of HPV vaccine to males was not published until December 2011, those vaccination rates are not reported in this figure.
