The COVID-19 Vaccine at FDIHB, Inc.

On December 14, 2020 at 11:30am, Tsehoostooí Medical Center (TMC) received its first shipment of Pfizer-BioTech COVID-19 Vaccine in part with the Navajo Area Indian Health Service (NAIHS) COVID-19 vaccine distribution plan.

Due to the unique rollout of the COVID-19 Vaccinations, the Fort Defiance Indian Hospital Board, Inc. (FDIHB) has instituted an Incident Management Team (IMT) that is responsible for the planning and distribution of COVID-19 vaccines. FDIHB is following the Centers for Disease Control’s (CDC) recommendations as well as working closely with the Navajo Area Indian Health Service.

Currently, the FDA approved Emergency Use Authorization (EMU) of two COVID-19 vaccines, one from Pfizer and one from Moderna that are two-dose series separated by 21 to 28 days. FDIHB is receiving the vaccines through IHS. FDIHB’s plan is for each vaccinated person to receive two doses of the same brand of COVID-19 vaccine, as brands are not interchangeable. Current recommendations are to fully vaccinate initial populations before expanding to additional target populations.

FDIHB has adopted the following prioritization listing provided by the Navajo Nation and Navajo Area Office IHS.
