AMANA — Whirlpool Corp. is administering vaccines to 1,170 of its employees this week.The company, which employs about 3,000 at its Amana facility, received the Pfizer-BioNTech vaccines Monday and plans to finish the first wave of vaccinations Thursday.More workers requested the vaccine than there are doses available, said R.J. Corning, Whirlpool’s senior director of human resources.Corning said he expects 90 percent of the available vaccines to be administered by the end of the day Wednesday.It’s probably the first mass vaccination site for Whirlpool, Corning said, which employs about 77,000 people globally.“For something this size and scale, it’s the first for us,” Corning told The Gazette.
