The volume of the Moderna booster dose is 0.25 mL (half the volume of the primary dose). Both 0.5 mL primary doses and 0.25 mL booster doses can be drawn from the same vial. The Moderna COVID-19 vaccine is supplied in two multiple-dose vial presentations:

•            A multiple-dose vial containing 5.5 mL (i.e., Moderna 10-dose)

•            A multiple-dose vial containing 7.5 mL (i.e., Moderna 14-dose)

When extracting only booster doses or a combination of primary series and booster doses, the maximum number of doses that may be extracted from either vial presentation should not exceed 20 doses; the Moderna COVID-19 vaccine vial stopper should not be punctured more than 20 times. Once punctured, multidose vials of the Moderna vaccine must be used within 12 hours.

Despite the volume of the booster dose being 0.25 mL, providers should still report a full dose as administered in ImmPact. At this time ImmPact pulls a full dose from inventory even if your EMR sends a partial dose. We are working on a fix for this issue. Until we have installed the fix you will need to modify your inventory quantities and add doses. Use the reasonVial Did Not Contain All Doses.
