Appendix : Ascertainment of Vaccination Status
Influenza vaccination: Respondents were asked if they had received an influenza shot or nasal spray in the past 12 months and if so, in which month and year.
Pneumococcal vaccination: Respondents were asked if they had ever had a pneumonia shot. There were no questions in the 2015 NHIS to ascertain pneumococcal vaccination by type of vaccine (23-valent pneumococcal polysaccharide vaccine or 13-valent pneumococcal conjugate vaccine).
Tetanus vaccination: Respondents were asked if they had received a tetanus shot in the past 10 years. Respondents who had received a tetanus shot in the past 10 years were asked if their most recent shot was received in 2005 or later. Respondents who had received a tetanus shot since 2005 were asked if they were told that their most recent tetanus shot included the pertussis or whooping cough vaccine.
Hepatitis A vaccination: Respondents were asked if they had ever received the hepatitis A vaccine, and if yes, how many doses were received.
Hepatitis B vaccination: Respondents were asked if they had ever received the hepatitis B vaccine, and if yes, whether they had received ≥3 doses or <3 doses.
Herpes zoster vaccination: Respondents were asked if they had ever received a shingles vaccine.
HPV vaccination: Respondents were asked if they had ever received an HPV shot or cervical cancer vaccine, and if yes, age at the first dose.
Classification as Health Care Personnel
Adults were classified as health care personnel if they reported that they currently volunteer or work in a hospital, medical clinic, doctor’s office, dentist’s office, nursing home, or some other health care facility including part-time and unpaid work in a health care facility as well as professional nursing care provided in the home.
Ascertainment of Health Insurance Status
Adults were considered insured if they reported having public health insurance coverage (Medicare, Medicaid, military health care [TRICARE/VA/CHAMP-VA], Indian Health Service, state-sponsored health plan, or other government program insurance) or private health insurance coverage.
Ascertainment of Having a Usual Place for Health Care
Respondents were asked if there is a place to which they usually go when sick or need advice on their health. Respondents answering “yes” were defined as having a usual place for health care.
