With the announcement that the COVID-19 vaccine manufactured by Pfizer has been given full approval from the Food and Drug Administration (FDA), the Pentagon’s top spokesperson told reporters on Monday that the Pentagon will soon mandate the vaccine for all servicemembers.

Defense Secretary Lloyd Austin is “prepared to issue updated guidance requiring all service members to be vaccinated,” Pentagon Press Secretary John Kirby said.

He added that a “timeline for vaccination completion will be provided in the coming days.”

“We’re going to move forward, making that vaccine mandatory. We’re preparing the guidance to the force right now. And the actual completion date of it, in other words, how fast we want to see it get done, we’re working through that guidance right now.”
