Meatpacker JBS USA has said that nearly 700 workers at a pork production plant in Beardstown, Illinois, had received the first dose of a Covid-19 vaccine on site, calling it one of the largest vaccination efforts for food workers, Reuters reported.

The workers at the plant would get the second dose in March, the company said. The plant employs more than 1,900 people.

JBS said last month it would offer $100 to workers who got the vaccine.
