"Heroes for Babies" are special American Red Cross blood donors with O-negative or O-positive blood who are also CMV-negative (never exposed to cytomegalovirus). Their blood is crucial for newborns and infants with underdeveloped immune systems, as it prevents dangerous infections. Who are they? Donors with O+/- blood that test negative for CMV antibodies. Why they are heroes: They provide the safest blood for premature babies, infants in intensive care, and, in some cases, patients with weakened immune systems. What is CMV? A common virus found in over half of adults by age 40, which is generally harmless to adults but dangerous for newborns. How to help: Regular blood donors can be tested for this status. The Red Cross calls these donors "Heroes for Babies" because this blood is in high demand for pediatric, trauma, and emergency situations. Recognition: These donors may receive special recognition and rewards from the Red Cross for their lifesaving contributions.
