CVS, Walgreens waste more COVID vaccine than most states combined, data shows COVID-19 vaccines readily available across the nation Replay Video Two national pharmacy chains that the federal government entrusted to inoculate people against COVID-19 account for the lion’s share of wasted vaccine doses, according to government data obtained by KHN. The Centers for Disease Control and Prevention recorded 182,874 wasted doses as of late March, three months into the country’s effort to vaccinate the masses against the coronavirus. Of those, CVS was responsible for nearly half, and Walgreens for 21%, or nearly 128,500 wasted shots combined. CDC data suggests that the companies have wasted more doses than states, U.S. territories and federal agencies combined. Pfizer’s vaccine, which in December was the first to be deployed and initially required storage at ultracold temperatures, represented nearly 60% of tossed doses.
