Codes and Frequencies
For sample adults aged 50 and older who have had a Shingrix vaccine (SHOTSGRXEV) but do not know or refused to provide the year they had it (SHOTSGRXYR), SHOTSGRXC reports whether they received the shot before 2018 or in 2018 or later.
SHOTSGRXC is part of a series of variables initiated in 2018 covering shingles vaccinations. The Shingrix vaccine was made available in 2017, so SHOTZOSTC and SHOTSGRXC are asked to further clarify whether the shingles vaccine the respondent received was Zostavax or Shingrix. Please refer to the Description tab in SHOTSHNGEV for more information about shingles vaccinations.
The NHIS questionnaire was substantially redesigned in 2019 to introduce a different data collection structure and new content. For more information on changes in terminology, universes, and data collection methods beginning in 2019, please see the user note.
