Key Findings

• Compared with 2015 NHIS estimates, modest increases in vaccination coverage occurred for some vaccines and age groups but coverage decreased for one vaccine overall and in two age groups in one racial/ethnic category. Apart from these changes, vaccination coverage among adults in 2016 was similar to estimates from 2015.
  • Overall influenza vaccination decreased 3.1 percentage points to 70.4% among adults ≥65 years, and decreased among whites in all age groups except among adults 19-49 years (range: minus 2.2 – minus 3.5 percentage points).
  • Pneumococcal vaccination increased 3.3 percentage points to 66.9% among adults ≥ 65 years.
  • Vaccination of adults 19 years and older with tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis vaccine (Tdap) increased by 3.4 percentage points to 26.6% overall.
  • Hepatitis A vaccination increased by 14.8 percentage points to 23.7% among adults 19-49 years with chronic liver conditions.
  • Herpes Zoster (Shingles) vaccination increased 2.8 percentage points to 33.4% among adults 60 years and older and increased 3.1 percentage points to 37.4% among adults 65 years and older.
  • HPV vaccination (at least one dose) among females and males 19-26 years who had not received HPV vaccination prior to 19 years was 8.6% and 2.7%, respectively.
  • Coverage did not change for other vaccinations in other age groups and many adults remained unvaccinated with recommended vaccines.
• Racial and ethnic vaccination differences persisted for all vaccinations in this report with generally lower coverage for most vaccinations among non-Hispanic black, Hispanic, and non-Hispanic Asian adults compared with white adults. Vaccination differences widened for Tdap (blacks, all age groups) and herpes zoster (Asians, ≥65 years) (due primarily to increases among whites).

Conclusions/Recommendations:

• Many adults in the United States have not received recommended vaccinations and racial/ethnic vaccination differences persist.
• Influenza vaccination decreased among whites and overall among adults ≥65 years.
• While modest gains occurred in vaccination coverage for pneumococcal, Tdap, hepatitis A (persons with chronic liver conditions), herpes zoster, and HPV vaccination, coverage did not improve for other vaccinations and many adults remained unvaccinated with recommended vaccines.
  • Among adults 65 years and older:
    • Over one-third did not report pneumococcal or Td vaccination.
    • Approximately 4 out of 5 did not report Tdap vaccination.
    • Nearly two-thirds did not report a herpes zoster vaccination.
  • Among adults younger than 65 years with indications for pneumococcal vaccination, approximately 3 out of 4 did not report ever having been vaccinated.
  • Among adults 19-26 years recommended for HPV catch-up vaccination:
    • About 11 out of 12 females and 32 out of 33 males not vaccinated before 19 years did not report HPV vaccination (at least one dose).
