be done by comparing the actual vaccination stock count to the recordkeeping form. The
CDC also recommends using tally sheets to maintain track of vaccination delivery without changing the stock recordkeeping form for each dosage. Cold chain management is a complicated problem that includes vaccine predictions,
ordering frequency, storage capacity,
and planning (WHO, 2009). To ensure proper supply levels while limiting overstocking and waste, forecasting of anticipated consumption and ordering frequency is critical (Rogers et alb. Limiting stock levels to operational demands will save waste in the case
of vaccine cold chain failures, which might threaten a year's worth of vaccine inventory unnecessarily. In contrast, an efficient stock level would only put three months' worth of vaccine inventory at risk (ibid. When evaluating stock level consumption, the WHO
forecasting and planning tools are good resources to consult (WHO, 2009). Stock levels of vaccines and diluents should not exceed the capacity of refrigeration systems on-hand storage space while planning vaccine and diluent stock levels (Rogers, 2010b).
