Acela Truck Co., based in Belgrade, has found customers among the agencies vaccinating millions of Americans. Its latest product is a custom-built trailer suited for the health care workers administering those vaccines.

“We have developed very close relationships with Operation Warp Speed, with FEMA, [the Department of] Health and Human Services and a number of the very large state and federal agencies that have been involved in the COVID-19 response … So, we’ve been talking with them for many months about vaccination trailers,” said David Ronsen, president of Acela.
