The COVID-19 vaccination program in the U.S. Army Central’s area of operations is underway.

“The COVID-19 vaccine has begun coming into theater,” said Army Brig. Gen. Justin Swanson, commanding general of the Army Reserve 310th Expeditionary Sustainment Command.

Swanson is also the deputy commanding general of 1st Theater Sustainment Command, which is based at Fort Knox, Kentucky, and also has a forward deployed headquarters established at Camp Arifjan in Kuwait. The forward deployed headquarters, which operates as an operational command post, or 1st TSC-OCP, is staffed with rotations from subordinate echelons of mobilized active-duty and reserve component units, providing sustainment and logistics support to U.S. forces in Afghanistan, Iraq, and Syria, as well as to units throughout the Middle East.

The 1st TSC, working hand-in-hand with 3rd Medical Command-Deployment Support, coordinated the transport and storage of the vaccine in theater. The initial tranche or portion of the vaccine arrived around mid-January and administration began shortly after its arrival.

Those who received the initial doses of vaccine were at the top of a prioritized list of personnel, which 1st TSC developed in accordance with the Department of Defense’s vaccine distribution guidance.

“Some of the soldiers, even on our staff have been vaccinated—but only our medical personnel at this point,” said Swanson, who is himself a COVID-19 survivor.

“The priority is the same here as it is in CONUS,” said the general, who before his 1993 commission, served as a combat medic in the Louisiana National Guard. “As the vaccines and the number of doses grows, we have built a prioritization model for our entire footprint.”

In addition to prioritizing medical personnel, other military personnel targeted in the first phase of vaccinations are in jobs where their interactions with other Soldiers make them particularly vulnerable, he said.

The second tranche of vaccines, scheduled to arrive in the near future, will serve as the second doses for personnel, who received the first tranche, he said. Then, subsequent tranches are set to vaccinate personnel in Afghanistan and other regions.

Army Col. Jennifer Marrast Host, the commander of 3rd MCDS's forward headquarters at Camp Arifjan, said the vaccination program in theater is a priority for every one of her “Desert Medic” Soldiers.

The 3rd MCDS is responsible for executing strategic medical operations across the entire U.S. Central Command area of responsibility.

According to the colonel, the vaccine administered by her soldiers is produced by Moderna, which requires two doses approximately 28 days apart.

"We watch someone very closely for about 15 minutes after the injection to make sure they are not having a negative response," she said. "After that, they are ready to get back to work." Marrast Host said the side effects are relatively minor.

"There might be some muscle aching, localized swelling or a low-grade fever-you might just feel under the weather," she said.

"It is more likely that you would have some of the side effects after the second dose, but it is also sometimes after the first one," she said.

The colonel said the most important consideration for rolling out the vaccine to specific regions or installations is the availability of freezers and refrigerators.

"The vaccine must be frozen as it is transported around," she said. "After it is thawed, it is good to be used for 30 days, as long it is kept refrigerated--but it cannot be moved.

Swanson said distribution of the COVID-19 vaccine and COVID-19 mitigation are top priorities for the 1st TSC.

"What the 1st TSC will do from a distribution standpoint—one of the things that we do as our mission set—we will move the vaccine just like any other commodity that we move—and we move all commodities across the battlefield,” he said.

“Once it comes into theater, we will move it where it needs to be—any of the countries or locations, where we have U.S. forces—or forces that we will provide the vaccine for,” he said. “We have already gone through the first couple tranches of distribution and that will continue to grow, as will the number of doses continue to grow.”

The vaccine is currently voluntary for military personnel, but Swanson’s staff have surveyed troops to ask who is uncomfortable with the vaccine and who is willing to receive it.

“The vaccine is voluntary, at this point,” he said. “We understand who will volunteer to take the vaccine and who won’t—and we are prepared to support, once doses of vaccine hit the ground.”
