This figure is a line graph that depicts estimated vaccination coverage with selected individual vaccines and a combined vaccine series by age 24 months, by birth year 2011-2019, using 2012–2021 data from the National Immunization Survey-Child, in the United States. — Estimated vaccination coverage with selected individual vaccines*^,†,§,¶,**^,^†† and a combined vaccine series^§§ by age 24 months,^¶¶ by birth year 2011–2019*** — National Immunization Survey–Child, United States, 2012–2021

Abbreviations: DTaP = diphtheria, tetanus toxoids, and acellular pertussis vaccine; HepA = hepatitis A vaccine; HepB = hepatitis B vaccine; Hib = Haemophilus influenzae type b conjugate vaccine; MMR = measles, mumps, and rubella vaccine; PCV = pneumococcal conjugate vaccine; VAR = varicella vaccine.

* Four or more DTaP includes children who might have received diphtheria and tetanus toxoids vaccine or diphtheria, tetanus toxoids, and pertussis vaccine.

^† One or more MMR includes children who might have received measles, mumps, rubella, and varicella combination vaccine.

^§ Hib full series: primary series and booster dose, which includes receipt of ≥3 or ≥4 doses, depending on product type received.

^¶ HepB birth dose = 1 dose HepB administered from birth through age 3 days.

** Rotavirus vaccination includes ≥2 doses of Rotarix monovalent rotavirus vaccine, or ≥3 doses of RotaTeq pentavalent rotavirus vaccine. The maximum age for the final rotavirus dose is 8 months, 0 days.

^†† Influenza vaccine doses must be administered ≥24 days apart (4 weeks with a 4-day grace period); doses could have been received during two influenza seasons.

^§§ The combined 7-vaccine series (4:3:1:3*:3:1:4) includes ≥4 doses of DTaP, ≥3 doses of poliovirus vaccine, ≥1 dose of measles-containing vaccine, the full series of Hib (≥3 or ≥4 doses, depending on product type), ≥3 doses of HepB, ≥1 dose of VAR, and ≥4 doses of PCV.

^¶¶ Includes vaccinations received before age 24 months, except for the HepB birth dose, rotavirus vaccination, and ≥2 HepA doses by age 35 months. For all vaccines except the HepB birth dose and rotavirus vaccination, the Kaplan-Meier method was used to estimate vaccination coverage to account for children whose vaccination history was ascertained before age 24 months (35 months for ≥2 HepA doses).
