Merck Warehouse Locations Are Changing


Dear Health Care Professional:

Merck is continually looking for ways to improve our service to you and, as a result, will be changing the warehouse locations in the United States from where we store, pack, and ship your vaccine orders. This change will be effective Monday, May 1, 2017, and will provide added flexibility and efficiency as we strive to meet our shipping commitments to you.

While we expect this process to go smoothly, there will be a temporary disruption to our shipping schedule as we complete the move to the new warehouses. On Wednesday, April 26, and Thursday, April 27, Merck will only be shipping certain vaccines as outlined below. Please note that you can continue to place orders for all Merck vaccines during this time. We expect normal shipping (from the new warehouses) to resume on Monday, May 1. Additionally, United Parcel Service (UPS) will continue to deliver your orders.

Vaccines that will ship during warehouse transition:

  • M-M-R®II (Measles, Mumps, and Rubella Virus Vaccine Live)
  • ProQuad® (Measles, Mumps, Rubella, and Varicella Virus Vaccine Live)
  • VARIVAX® (Varicella Virus Vaccine Live)
  • ZOSTAVAX® (Zoster Vaccine Live)

All other Merck vaccines will not ship during the warehouse transition.

Please consider adjusting your ordering needs, as appropriate, to ensure you have adequate vaccine inventory on hand during this brief transition.

If you have questions, please contact your Merck Account Representative or call the Merck Vaccine Customer Center at 877-VAX-MERCK (877-829-6372), Monday through Friday, 8:00 AM to 7:00 PM, ET.

We appreciate your business and thank you for your understanding as we look to serve you better.
