Moderna announced today that ongoing development data related to the current formulation of the Moderna COVID-19 vaccine (mRNA-1273) could support a three-month refrigerated (2-8°C) shelf life for the vaccine in alternative formats. The company said this could facilitate easier distribution to doctor’s offices and other smaller settings if authorized. 

Currently, the Moderna COVID-19 vaccine is approved for storage up to 1 month at refrigerated temperatures (2 degrees to 8 degrees C) and up to 7 months in a standard freezer (-20 degrees C).

The Moderna COVID-19 vaccine also is the only authorized mRNA vaccine that does not require on-site dilution, the company noted.

Moderna also announced that it is working on formulations of mRNA-1273 and a next generation vaccine (mRNA-1283) that it believes will extend refrigerated shelf life even further.
