Mpox Dashboard Technical Notes

The Washington State Department of Health (DOH) is no longer listing positive cases in non-Washington residents, those cases are counted in a person’s state or country of residence.

DOH makes every effort to publish updates on Tuesdays (except for state holidays). 

Due to processing, there may be some lag time between when a local health jurisdiction or health care provider confirms a positive test or reports a vaccine dose and when that information is added to the data above.

Mpox Vaccine Summary

After April 30 through August, state health departments will have access to limited JYNNEOS vaccine through the strategic national stockpile where commercial vaccine is not available or accessible. DOH will continue to work with federal partners to understand availability of this supply and what the process will look like for providers to make requests.

Mpox Vaccines

There are two vaccines available for mpox: JYNNEOS and ACAM2000. The current mpox outbreak response has focused on distributing JYNNEOS. There have been very few administrations of ACAM2000, although this analysis monitors for them. JYNNEOS is administered in two doses, the second of which is recommended 24-35 days after the first dose. Below is a table of patient counts organized by JYNNEOS dose number.
