Codes and Frequencies
SHOTPNUEV indicates whether sample adults/persons ever had a pneumonia vaccination.
The pneumococcal pneumonia shot protects against the bacteria that causes the most common kind of pneumonia. It is generally recommended for persons who are over age 65, whose immune system is weakened, who are scheduled to have chemotherapy, or who suffer from a chronic illness such as diabetes, lung disease, or heart disease.
Along with universe changes, there were slight shifts in question wording and procedural changes for SHOTPNUEV.
As the question wording noted above indicates, proxy reporting (i.e., answers given by one household or family member for other household or family members) was allowed in 1989. In all other years, adult respondents answered the question for SHOTPNUEV only for themselves.
Proxy reporting is generally less accurate and complete than self-reporting, particularly regarding minor medical problems and brief contacts with health care professionals. Researchers should thus be particularly cautious about comparing results for SHOTPNUEV from 1989 to results from other years.
Finally, comparability may be impacted by the 2019 questionnaire redesign. The NHIS questionnaire was substantially redesigned 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.
