The American Red Cross reports that a donor’s immune response to the vaccine will not be disrupted by giving blood and does not reduce the antibody protection against the COVID-19 virus. Additionally, it’s OK to donate blood with antibodies from the vaccine.
The Red Cross also says that receiving a blood transfusion from someone who has had the COVID-19 vaccine is safe.
“It is possible that a donor’s antibody developed in response to the vaccine could be passively transferred via transfusion," Pampee Young, MD, chief medical officer for the American Red Cross, tells Verywell. “However, they would constitute a very minor amount of passively-transferred antibody in comparison to the recipient’s overall levels of antibodies.”
Blood Donation Eligibility
You are eligible to donate blood anytime after receiving a COVID-19 vaccine. As long as you are feeling healthy and well, there is no wait time necessary between the shot and blood donation.
According to the Red Cross, blood can also be donated in between the first and second vaccine doses as long as the recipient is not experiencing any side effects from the vaccine, such as muscle aches, headache, soreness, or fever. Blood donation can resume once side effects go away.
When You Should Not Donate Blood
Although giving blood is a great way to help those that are facing critical health situations, there are certain criteria that disqualify someone from donating blood either temporarily or permanently.
The World Health Organization (WHO) advises that you should not donate blood if you:
Are sick with the flu, sore throat, cold, or other infection Have had minor dental work done, you must wait 24 hours before donatingHave recently traveled to a country with a high risk of mosquito-borne infections Have engaged in “at risk” sexual behavior in the last 12 monthsTested positive for HIVHave ever injected recreational drugsHave given birth within the past nine monthsAre breastfeeding
Convalescent Plasma Donation
Early in the pandemic, the antibodies from donated plasma obtained from those who recovered from COVID-19 (referred to as convalescent plasma) were thought to be beneficial in treating those with an active infection. However, recent studies have shown that this is not the case, and according to the American Red Cross, people who are vaccinated are not eligible to donate convalescent plasma at this time.
Different Types of Blood Donation
There are several different types of blood donation: whole blood, plasma, and platelets. Each type has its own specific eligibility requirements.
Whole Blood Donation
Whole blood contains red blood cells, white blood cells, platelets, and plasma.
You can donate whole blood every 56 daysMost states require you to be 16 and olderYou must weigh at least 110 pounds
Platelet Donation
Platelets are the blood clotting components of blood and help the body stop bleeding when it is injured. Platelet donation is helpful for those that have cancer, chronic diseases, or have suffered a traumatic injury.
You can donate platelets every 7 days, up to 24 times a yearMost states require you to be 17 years and olderYou must weigh at least 110 pounds
AB Elite Plasma Donation
AB blood is the universal blood type for plasma donation. The American Red Cross estimates that only 4% of the population has this blood type.
During plasma donation, a machine collects the plasma from your blood and then returns the red blood cells and platelets back to your body. Plasma is beneficial to people with cancer, burns, and trauma patients.
You can donate AB elite plasma every 28 days, up to 13 times a yearYou myst have AB-type bloodMost states require you to be 17 years and olderYou must weigh at least 110 pounds
Why Blood Donation Is Important
Since there is not an artificial substitute for blood, physicians rely on blood donation to save the lives of approximately 4.5 million people each year.
Blood transfusions are used in surgery, for traumatic injuries, cancer patients, chronic diseases, and for those with blood disorders such as sickle cell anemia and hemophilia.
Medical facilities rely on a consistent supply of blood from donors to meet the needs of its patients and to ensure they are prepared for emergencies.
