Summary
Sometimes due the issues with the current Digital Vaccine, you may wish to return to the previous version of the DV. You cannot "rollback" a Digital vaccine, instead a different DV has to be distributed to the device. Once the distribution is complete, the DV currently on the device will be overwritten, and any filters that are on the more recent DV will be removed from the device.
