The Great American Blood Shortage

The Great American Blood Shortage

Since the onset of the Coronavirus pandemic, America’s blood supply has taken a dramatic hit

American Red Cross blood drives collect nearly 40% of the nation’s blood supply and are traditionally set up in public locations, such as college campuses. At the start of the pandemic, these locations experienced shutdowns due to Covid-19 protocols. Inevitably, the blood supply went down with the shutdowns. Unfortunately, donor numbers have yet to fully recover and factors contributing to the nationwide blood deficit have continued to snowball from there.

The need for blood donations following the devastating tornadoes of this past weekend focused the spotlight on the blood supply shortages that were already there. Hospitals across Tennessee have been continuously stressing the severity of the blood supply shortage since the summer. Even before the severe storms of December 11th hospitalized Tennesseans in need of lifesaving care, doctors in major hospitals across the state preemptively outlined contingency plans for blood rationing if their supplies ran out.

It’s Not Just About Donations

At this point, the problem has shifted from just being a low supply problem to being a low supply and high demand problem. During the pandemic, elective surgeries were postponed due to hospital capacity, staffing, and precautions. This led to an elective surgery surge when hospitals began to allow them again. An uptick of cancer patients and other patients is also contributing to the increased demand on the blood supply as people are back to attending regular checkups with their doctors and receiving diagnoses.

Blood Transfusion Hang-Ups

Covid-19 diminished people’s already low comfort levels with donating blood and receiving blood transfusions. As far as receiving blood goes, respiratory viruses, including Coronavirus, are not known to be spread through blood transfusions. It’s also worth noting that there are no documented cases of Covid-19 that’ve been transmitted through blood transfusions. Additionally, a study conducted in April 2021 concluded that any risk of contracting Coronavirus through a transfusion is negligible.

On the flip side, now deep into the pandemic’s vaccination era, some patients who did not get the vaccine are weary of receiving a blood transfusion from a vaccinated donor. This is a more nuanced obstacle to hurdle. Typically, the blood received by patients getting a blood transfusion only contains red blood cells. Professor of medicine and infectious disease expert at Johns Hopkins, Dr. Shmuel Shoham explains that antibodies and white blood cells are separated from the blood that is prepared for transfusion. That said, the American Red Cross donor guidelines still require patients who received vaccinations and boosters to provide the name of their vaccine/booster manufacturer.

No Positive Effects, Either

Just as Covid-19 is not known to be transmitted via blood transfusions, there is no documented benefit from receiving a blood transfusion from a person who has Covid-19 antibodies. Towards the beginning of the pandemic, plasma from donors who had Covid-19 immunity (plasma is made up of proteins, hemoglobin, and other components that are separated out from red blood cell transfusions) were thought to have the potential of helping combat the viral load of Covid-19 patients. The push for plasma donations from those who had Covid-19 antibodies was abandoned with the conclusion that plasma transfusions had no detectable benefits for severely ill patients. Though plasma with antibodies does help when used as a therapeutic during the early onset of Covid-19 symptoms (similar to the therapeutic use of monoclonal antibodies outlined in this Pamphleteer article), prioritizing the practice in hospitals where patients are most likely experiencing severe symptoms already was found to be impractical.

There Truly is a Dire Need for Blood in Tennessee

When all is said and done, donating your blood in this time of great need will absolutely help save a life. If you’d like to donate blood, you don’t have to go to a blood bank and wait. Instead, you can set up an appointment with Blood Assurance. All blood donated through Blood Assurance stays within the state.


Depending on the timing, you can also do a quick google search and see if any donation drives are doing giveaways. The American Red Cross has been doing raffles, giving away gifts cards, and more for donating.
