ISA Calculations SELV Requirements

Items in red are different from vrMIS

*for BCG, vrMIS had a doses per year value of 1.5, and a buffer stock of 0%. SELV doesn't allow decimal values for number of doses, so to make the resulting ISA the same I've changed doses per year to 1 in SELV, and buffer stock to 50%.

Product	Doses	vrMIS Formula	Target Population Percentage	Doses per patient per year	Wastage Factor	Buffer Stock	Minimum Quantity	Max Quantity
BCG	20	population * 0.04 * 1.5 / 12 * 1.25; isa.bcg = (quantity > 100) ? Math.ceil(quantity) : 100;	4	1* vrMIS was 1.5.	1.25	50%* vrMIS was 0.	100	0
Polio 20 dose	20	population * 0.039 * 4 * 1.1 / 12 * 1.25	3.9	4	1.1	25%	0	0
