Refer to Reporting dictionary for reference.

Label: "Children (0-23 months) up to date on immunizations"
Note below: "OPV 0 not included"

Calculations:

Green - Count of children aged 0 to < 24 months who are currently not due or due for any vaccinations.

Red - Count of children aged 0 to < 24 months who are currently overdue for at least one or more vaccinations.

Note: 0PV 0 is not counted in this. Included vaccines are: BCG, OPV 1-3, PCV 1-3, Penta 1-3, Rota 1-2, IPV, YF, MCV 1, and MCV 2 only.

QA 19 June release

• Indicator doesn't seem to update at first. I am using a new login with no data to test (chaseven). I registered a new child (0 days old) and did a home visit and recorded both OPV 0 and BCG vaccines, so the child should be counted as up to date on immunizations, but the indicator didn't update (it stayed on the null state).
• Then, when I registered a new child who was 6 months old and I recorded all of their vaccines up to date, I would expect the indicator to update to show 2 children up to date on immunizations, but instead it updated and showed 15 children NOT up to date. I think it's counting the number of immunizations instead of the number of children. See below. I'm expecting it to be on 2 green.

Suggested Fix:

• Look into the counts returned by the 2 queries defined in the indicator definitions YAML file.
• Confirm counts for only included vaccines
• Look into aggregation of the latest count in updateLatestCount() function to ascertain the correct count is returned
