Vaccine Allocation: Which groups will get how much?

As part of our collaboration with the Montgomery County, Maryland, Advanced Practice Center for Public Health Emergency Preparedness and Response, we have developed a Vaccine Allocation Model.

The Vaccine Allocation Model is intended to help public health officials determine how many persons in different target groups can receive treatment if the number of vaccinations available is limited. This can be done on a local, state, or national scale.

The Vaccine Allocation Model is a Microsoft Excel workbook that can be used either in the advance planning stages of a vaccination campaign or for support during a vaccination campaign.

It is based on information published in the Guidance on Allocating and Targeting Pandemic Influenza Vaccine.

I would like to thank Rachel Abbey at Montgomery County, Maryland, and Hiro Toiya at the Hawaii State Department of Health for their feedback on draft versions of the model.
