**BOX 2_ HepA_B /TABLE 1. Estimated proportion of adults ≥19 years who received hepatitis A vaccination, by age group, increased-risk status,* and race/ethnicity† — National Health Interview Survey, United States, 2017**

In 2017, reported hepatitis A vaccination coverage (>2 doses) was 10.9% for adults >19 years, and 6.1% for adults >50 years, similar to the estimates for 2016, while coverage among adults 19-49 years was 15.7% in 2017, a 2.3 percentage points increase compared with 2016. 

Among adults 19-49 years, compared with whites (16.3%), coverage was lower for blacks (11.7%) and Hispanics (13.4%), while coverage was higher for Asians (23.3%).

Among adults >19, 19-49, and ≥50 years, vaccination coverage was higher among those who had traveled outside the United States to a country in which hepatitis A is of high or intermediate endemicity than among respondents who did not travel outside the United States or had traveled only to countries in which the disease is of low endemicity.

Hepatitis A vaccination coverage among adults >19  and >50 years with chronic liver conditions was 20.8% and 19.2%, a 7.9 percentage points and 10.0 percentage points increase compared with the 2016 estimates, respectively.

**BOX 2 _ HepA_B /TABLE 2. Estimated proportion of adults ≥19 years who received hepatitis B vaccination,* by age group, increased-risk status, † and race/ethnicity§ — National Health Interview Survey, United States, 2017**

In 2017, reported hepatitis B vaccination coverage (>3 doses) was 25.8% for adults >19 years, 34.3% for adults 19-49 years, and 16.6% for adults >50 years, similar to the estimates for 2016. 

Among adults 19-49 years, coverage for blacks (30.7%) and Hispanics (27.3%) was lower than that for whites (36.6%).

Among adults >19, 19-49, and ≥50 years, vaccination coverage was higher among those who had traveled outside the United States to a country in which hepatitis B is of high or intermediate endemicity than among respondents who did not travel outside the United States or had traveled only to countries in which the disease is of low endemicity.

**Table 1 - Trend. Estimated proportion of adults aged ≥19 years who received hepatitis A and hepatitis B vaccines, by age group and high-risk status — National Health Interview Survey, United States, 2010-2017**

Hepatitis A and hepatitis B vaccination coverage among adults aged ≥19 years during the period 2010 through 2017 is presented in trend table 1. Hepatitis A vaccination coverage among all adults aged ≥19 years increased from 8.1 in 2010 to 10.9 in 2017 (p = 0.03 [average annual percentage points increase = 0.2]), but coverage did not change among travelers and non-travelers aged ≥19 years, and adults with chronic liver conditions aged ≥19 years. Hepatitis B vaccination did not change among adults aged ≥19 years, travelers and non-travelers aged ≥19 years, and adults aged ≥19 years with chronic liver conditions.

**Box2_ HepA_B / Figure** is a line graph of hepatitis A and hepatitis B vaccination coverage among adults aged ≥19 years by age group over time, where the y-axis represents vaccination coverage expressed as a percentage from 0% to 100% in increments of 10, and the x-axis is the survey year.
