Grocery chains step up efforts to expand vaccinations Grocery retailers are expanding COVID-19 vaccine distribution, with industry leader Walmart today sketching out its vaccination game plan. In a blog post on Friday, Dr. Cheryl Pegus, executive vice president of health and wellness at Walmart, said the retail giant expects to be able to deliver 10 million to 13 million doses of coronavirus vaccine per month at full capacity, depending on government allocations and manufacturer supply. She noted that Walmart has been readying for the vaccination buildup by training thousands of pharmacists and pharmacy technicians, creating a new digital scheduling tool for vaccine appointments, and partnering with state and federal agencies on vaccine allocations.
