The American Red Cross’ blood supply has hit a 15-year low, USA Today reports.

According to the nonprofit’s website, it got 50,000 fewer donations than it expected in June and its supply has dipped to emergency levels. Though summer is typically slow because schools are closed, temperatures heat up and vacationers go away, this year has proven to be worse than usual.

"We just aren't seeing the donors coming through the door right now," American Red Cross spokeswoman Karen Stecher, told USA Today.

The alarming figures may be attributed to a number of factors, including donors having taken off earlier than usual for getaways and the fact that many Red Cross blood drives were canceled because July 4 fell in the middle of the week, the nonprofit announced on its website.

Donor sites across the country are feeling the pinch.

A center in Wichita Falls, Texas is seeing an average of just five walk-in blood donors a week, the Times Record News reports. An additional three donors a week would enable the outpost to maintain its blood supply, Katrina Farmer, North Central Red Cross executive director, told the Huffington Post.

The need demonstrates the value of each person who gives blood. One donor can save three lives, according to the news outlet.

On a national level, in order for the Red Cross to adequately serve patients at more than 3,000 hospitals and transfusion centers, it must collect 17,000 pints every day.

The dearth in blood supply can have far-reaching effects. A physician, for example, may have to postpone an elective surgery if the necessary blood products aren’t readily available, Dr. Richard Benjamin, chief medical officer for the American Red Cross, said on the nonprofit’s website.

“In a worst case scenario, a physician may have to forego performing a more serious procedure for a patient because of a shortage of blood,” Benjamin said. “We need to do everything we can to make sure it doesn’t get to that point.”

But those who are reluctant to give, can draw inspiration from donors who make giving blood a part of their regular routine.

Jess Vickery, who passed away earlier this month from brain cancer, gave blood 581 times over the course of 25 years, myfoxhouston.com reports.

The do-gooder, who was a retired deputy, was honored by the Harris County Sheriff’s Office at its first-ever “Donation Day.”

“He was a wonderful giving man,” Vickery’s daughter told the news outlet. “I’m just very honored to be here and to donate for him.”
