For sample children who had more than one H1N1 vaccine dose, VAC2H1N1DMO reports the month the child received his or her second most recent H1N1 flu vaccine.
VAC2H1N1DMO should be interpreted in conjunction with VAC2H1N1DYR, which reports the year of the child's second most recent H1N1 vaccination.
The survey questions associated with VAC2H1N1DMO were removed from the NHIS in August 2010.
VAC2H1N1DMO is part of a series of variables introduced in 2010 dealing with immunization. For other related variables, please use the IPUMS NHIS search function and drop-down menus.
