Researchers looked at data from patients’ medical records that were reported to the Center for International Blood and Marrow Transplant Research® (CIBMTR®). About 40%, or 4 out of 10 people, had moderate or severe COVID-19. One month after getting COVID 19, 30%, or 3 out of 10 people had died. Based on available data, this is much higher than patients who never had BMT.
People were more likely to survive if they were younger than 50 years old, female, or were at least a year past allogeneic BMT when they got COVID 19. The study did not look at why people who got BMT were at higher risk of severe COVID-19 disease.
It’s important for everyone to get vaccinated against COVID-19, researchers said. This will help protect people who need or had a BMT. It is unknown how well the vaccine works in patients who had BMT.
