SEATTLE — In Washington state, Amazon has started vaccinating thousands of its warehouse and delivery workers, contractors and their families.

Amazon.com Inc. hosted its first clinic on Monday. The Seattle Times reported company spokesperson Karen Riley Sawyer says a second vaccination clinic is set to open Tuesday at a Spokane warehouse. That will be followed by additional company vaccination opportunities at other facilities across the state.

Critics have claimed the company didn’t take proper safety precautions for its workers during the coronavirus pandemic. While some staff worked from home, about 1 million warehouse workers globally were required to report to their facilities as workloads soared because of increased demand for online shopping. But some warehouse workers stopped showing up as concerns increased about the coronavirus.

Amazon then rolled back its COVID-19 benefits, including pay increases and unlimited sick leave. The company has said its workers contracted the virus at rates comparable or lower than the national average.
