I am working on complete immunisation of children under 1 year old. I am using Cambodia DHS 2014.

I am currently using KHBR73FL birth recode.dta. Am I analysing it correctly?

I cannot produce the same result as shown in table 14.2 and 14.3 in section 2 of Child Health Report page 153 and 154.

The result of receiving all basic vaccines by the age of 1 from all sources of information are different in table 14.2 is different 14.3.

Hi T.T. Ponlok,

I am only able to fully replicate Table 14.3 Vaccinations by background characteristics

See code below.

Good luck

clear all
set matsize 800
set mem 1g
set maxvar 9000
cd "..."
use "KHBR73FL", clear
set more off

Dear Mlue

I still cannot figure out why result complete all basic vaccines from all sources in table 14.2 (65.3%) is different from table 14.3 (73.4%).

If you look at table 14.2, All basic from either source is 73.4, just as in table 14.3. The figure of 65.3 in table 14.2 is for vaccinations given in the first year life (by age 12 months), not all vaccinations given irrespective of time.

The calculation of vaccinations given in the first year of life is quite complicated. See the updated Guide to DHS Statistics and find Child Health, Vaccination. For vaccinations given by age 12 months, you are interested in indicator 4 (Percentage of children age 12-23 months who received specific vaccines by appropriate age) and in particular the Calculation section.

Dear Trevor

I cannot calculate vaccination coverage by appropriate age (complete all basic vaccines by the age of 12 months) for children aged 12 to 23 months old.

I am using code given to me by Mr/Ms Mlue.

The code given by Mlue does not calculate vaccinations by appropriate age. It only calculates vaccinations given by any age. We do not have code in Stata for calculating vaccinations by appropriate age, but the Guide to DHS Statistics provides a detailed description of how to calculate vaccinations by appropriate age.
