Description

For sample adults and sample children who had a nasal spray flu vaccine in the past 12 months (SPRAYFLUYR), SPRAFLUYRMO reports the month of the most recent nasal spray flu vaccine. Interviewers asked, "During what month and year did [you/sample child] receive [your/his/her] most recent flu nasal spray?" The complementary variable SPRAFLUAGOYR reports the year of the most recent flu nasal spray.

According to the Field Representative's Manual for 2005 forward, if a respondent gave a date prior to 12 months ago for their most recent nasal flu vaccine, the interviewer was prompted to verify if the date given was correct. If the respondent confirmed that the date was prior to 12 months ago, the interviewer was to change the respondent's answer from "yes" to "no" for SPRAYFLUYR (and the individual became defined as "not in universe" for SPRAFLUYRMO and SPRAFLUAGOYR). Thus, one rationale for asking about the date of the most recent flu nasal spray was to check whether respondents used the appropriate reference period in their responses to SPRAYFLUYR.

Along with collecting information about the nasal flu vaccine, the survey collected information on whether sample adults and sample children had a flu shot in the past year (SHOTFLUYR) and, if so, the month and year of their most recent flu shot (SHOTFLUYRMO and SHOTFLUAGOYR). The Manual text about the inquiry into the date of the most recent flu shot suggests another rationale for asking about the timing of both forms of flu vaccination: "This helps determine [whether the reported flu vaccination was] for this flu season or last year."

Comparability

Up until 2009, SPRAYFLUYRMO is completely comparable over time.

In 2009, the following introduction was added to the survey question for SHOTFLUYR, to direct respondents to distinguish between regular flu vaccinations and H1N1 vaccinations: "The next questions are about seasonal or regular flu vaccination. Please do not include H1N1 or swine flu vaccination." While the addition of this statement technically changes the wording of the question, including this text makes the 2009 results on flu vaccination more comparable to the results for earlier years than would otherwise be the case.
