Hi, all. I'm writing to share this attached report that investigates:

How concentrated or dispersed should COVID vaccination delivery be in LMICs?

Should COVID-19 vaccines be delivered through a few large, centralized vaccination locations (concentrated) or through many small vaccination locations closer to target populations (dispersed)?

How should delivery strategy change for different geographic areas and with different levels of available vaccine supply (and delivery throughput)?

How about if we are aiming to target vulnerable populations while also aiming to minimize delivery cost?

This report is authored by contributors from Coupa (formerly LLamasoft), JSI, PATH, UNICEF, and VillageReach with funding and guidance from the Bill and Melinda Gates Foundation. Please share your reactions and questions! We look forward to responding to you.

Hi Robert - thank you for the question. If countries anticipate shorter expiry, they would need to use the vaccine quickly in a very short period of time. Hence, please consider and use the results for high throughput (7%) as you read the document. Countries may need to ramp up to very high levels of throughput in the short-run. 


Thank you,

It's great to see such a stimulating document as this which integrates the interconnected operational aspects which should be considered when designing vaccination programs.  Congratulations. 

I have heard that the shelf life of Covid vaccines is much shorter than immunization prgrams are accustomed to.  Also one can anticipate that some vaccines donated by well-supplied countries may have already used up some of their available shelf life.  How should readers consider those shorter expiry issues as they review your document?
