COVID-19: Vaccinator Guidance for Johnson & Johnson (Janssen) Vaccine


As of September 10, Wisconsin is again able to order Johnson & Johnson COVID-19 vaccine from the federal government. There are currently no allocations or order caps for this vaccine.

Please be good stewards of this important public health resource:

  • Use what you currently have on hand.
  • Continue to first check in the Wisconsin COVID-19 Vaccine Exchange prior to ordering additional Johnson & Johnson in the Wisconsin Immunization Registry (WIR).
  • Order in small quantities in WIR when you need more doses.   
  • Ensure that you have updated information on so folks seeking Johnson & Johnson can easily find where it is being offered.

Johnson & Johnson and Moderna COVID-19 vaccines are not authorized for and cannot be administered to anyone under 18 years old, under any circumstances.

Johnson & Johnson, Pfizer, and Moderna COVID-19 vaccine products are not interchangeable. The Advisory Committee on Immunization Practices (ACIP) does not state a product preference. A person may receive any recommended COVID-19 vaccine series.


Johnson & Johnson’s COVID-19 vaccine is:

  • A single-dose, viral vector COVID-19 vaccine.
  • Transported and stored at refrigerated temperatures of 2 to 8 degrees Celsius.
  • Authorized for people 18 years of age and older for the prevention of COVID-19 infection.
  • Administered intramuscularly.


Do not administer the Johnson & Johnson COVID-19 vaccine to individuals with a known history of a severe allergic reaction (for example, anaphylaxis) to any component of the Johnson & Johnson COVID-19 vaccine. The list of ingredients is available in the clinical considerations.

DHS guidance and updates

 Shelf life of Johnson & Johnson COVID-19 vaccine

The FDA has authorized an extension of the shelf life for the Johnson & Johnson (Janssen) COVID-19 vaccine from 4.5 months to 6 months (an additional 45 days). The decision is based on data from ongoing stability assessment studies, which have demonstrated that the vaccine is stable at 6 months when refrigerated at temperatures of 36 – 46 degrees Fahrenheit (2 – 8 degrees Celsius). This extension applies to refrigerated vials of Johnson & Johnson COVID-19 vaccine that have been held in accordance with the manufacturer’s storage conditions.

Vaccine providers should take the following steps:

Step 1. Visit to confirm the latest expiration dates of vaccine, including those currently available for administration throughout the U.S.

Step 2. Update the expiration date for your inventory in WIR. To Extend an Expiration Date in WIR do the following:

  • Click “Manage Inventory” on the left menu bar in WIR.
  • On the manage inventory screen click “Show Inventory” on the top right of the screen.
  • Find the expiration date you want to change using the lot number of the Janssen COVID-19 Vaccine.
  • You should already have the new extended expiration dates for each lot in your inventory from using as outlined in Step 1 above.
  • Click on the blue Janssen COVID-19 link on the line with the corresponding lot number of the date you want to change.
  • This will take you to the "Edit Vaccine Inventory Information" screen. Find the “expiration date” field, and update the date to the new extended expiration date.
  • Click "Save" on the top right of the screen.

Repeat this process for each lot of Janssen COVID-19 vaccine in your inventory.

Step 3. (if applicable) update the expiration date on the Vaccine Exchange.

COVID-19 vaccines that are authorized under an emergency use authorization (EUA) do not have fixed expiration dates, and their expiration dates can be extended as we get more stability data. Always be sure to check the manufacturer’s website to obtain the most up-to-date expiration dates for COVID-19 vaccines you have on hand.

 How to determine the expiration date

The expiration date is not printed on the vaccine vial or carton. To determine the expiration date:

  • Scan the QR code located on the outer carton, or
  • Call 800-565-4008, or
  • Go to

Write date on carton. As the expiration date approaches, check the expiration date again. Use CDC's Vaccine Expiration Date Tracking Tool to document expiration date changes. For more guidance visit the Janssen COVID-19 Vaccine website.
