Vaccination Program Logistics: Doses, Wastage, Cold Chain & Clinic Capacity

What you'll build

What you will be able to do

Each lab ends with a concrete result that you build yourself and the checker confirms, cell by cell.

• Turn the district population into a target population and the number of people to vaccinate per age group, then express the overall goal as a single coverage rate.
• Turn people to vaccinate into doses: the doses if everybody completes the schedule, the doses expected with drop-out, the share of doses drop-out removes and the average doses per week.
• Calculate the wastage rate and the wastage factor per clinic and for the district, then see how session size drives wastage with 10-dose vials.
• Convert the maximum stock of each facility into litres of cold storage, compare it with the fridge net capacity, flag the facilities that run out of space and size the extra fridges for the district store.
• Calculate each clinic's daily capacity, the days it needs for its doses, the vaccinators it would need to finish within 40 days and how many clinics miss that target.
• Calculate how many bookings each week needs so that enough people actually turn up, compare it with slot capacity and size the shortfall.
• Calculate weeks of stock, reorder points, which facilities must reorder and the order quantity in whole boxes for six vaccination sites.
• Track the campaign week by week: cumulative doses, dose-1 coverage and full coverage of the target population, the week the goal is reached, the people still waiting for their last dose and a coverage chart.
