Setting-Specific Model Inputs for a Hypothetical Population, Using Generic Model Inputs Published Elsewhere

Model input Value Notes
No. of subpopulations 2 1 undervaccinated subpopulation and 1 general population
Initial age distribution
0–2 mo 0.01 Age groups of ≥5 y from a previously published hypothetical population [2] were split into groups of 5–15 y and ≥15 y, according to the age distribution in “less developed regions excluding China” [75], to accommodate the subsequently developed generically mixing age groups of 0–4, 5–14, and ≥15 y [33]
3–59 mo 0.15
5–14 y 0.25
≥15 y 0.59
Birth rate, births/person/y 0.02 Adopted from previously published hypothetical population [2]
Death rate, deaths/person/y 0.02 Adopted from previously published hypothetical population [2] and applied equally to each age group
Basic reproduction number 10 Adopted from previously published hypothetical population [2]
Proportion of transmission via oropharyngeal route 0.3 Adopted from previously published hypothetical population [2]
Average per-dose OPV take rate for serotype 1 0.5 Similar to typical values in low-income countries for bivalent OPV [33, 34]
Routine immunization coverage with exactly 3 OPV doses in the general population 0.95 Fixed well above the theoretical threshold of 0.92 implied by the other setting-specific inputs from this table

Generic model inputs are from reports by Duintjer Tebbens et al [33] and Thompson et al [34].
