For years where NI reports two-dose coverage, and we are unaware of any post-event coverage surveys, we roughly assume the same coverage was achieved in each semester.

2020 S10%
NI reported that one campaign was held in 2020. We assume 0% coverage in the first semester and, because we don't have specific data for the second semester, we assume the average coverage achieved in other years prior to NI's involvement.

Adjustment for one-dose vs. two-dose coverage120%We make an additional rough, 20% upward adjustment to account for the fact that Nutrition International shared administrative data on two-dose coverage, which describes children who received two doses of VAS that were spaced 4-6 months apart. We expect two-dose coverage to underestimate coverage per semester since it misses children who received a single dose of VAS in either semester. This is a subjective guess.
