Information is based on reporting by the vaccinating site as of 11:59 PM on 02/12/2021 in the state’s immunization information system DelVAX. Location data are based on the address of the vaccine recipient’s residence.

More doses have been administered than are showing up on the vaccine tracker. This is because of health care provider delays in reporting doses administered to DelVAX.

The vaccine tracker is now receiving data from the State’s vaccination information system, DelVAX, via a new data transport process. This allows for more complete information on race and ethnicity to be displayed in the "Cumulative Doses Administered By Race/Ethnicity" chart.

Due to the transition to the new data feed, there may be a temporary lag in reporting information on the most recently reported vaccinations from the day prior.
