Following is a response from Senior DHS staff members, Tom Pullum and Keith Purvis:
You need to use b19, rather than v008-b3, for age in months.
There is NOT a problem with the DHS construction of this indicator. To construct it, you use the interval since the date on the health card, and you ALSO use h34, which is based on a separate question about whether there was a vitamin A supplement in the past 6 months. The Stata code below will match the 4th and 5th columns in Table 11.12 of the Kenya 2022 final report.
* Construct indicator for Vitamin A supplement in the past 6 months, children under 5
* Table 11.12, Kenya 2022 DHS Survey
use "...KEKR8BFL.DTA", clear
gen vas=0 if b5==1 & b19>=6 & b19<=59
label variable vas "Received Vitamin A supplement"
replace h33d=15 if h33d==98
replace h33m=. if h33m==98
replace h33y=. if h33y==9998
replace vas=1 if vas==0 & h33>=1 & h33<=3 & (mdy(v006,v016,v007)-mdy(h33m,h33d,h33y)<6*30.4375)
replace vas=1 if vas==0 & h34==1
tab v190 vas [iweight=v005/1000000], row
