WASHINGTON — As we wait for the rollout of a COVID-19 vaccine, researchers are continuing to look for the best way to treat patients. And not all convalescent plasma donations are created equal.
Blood taken from the sickest COVID-19 patients may make for the most effective convalescent plasma therapy treatment. Researchers at Johns Hopkins University are studying how it works.
Plasma from recovered patients contains antibodies and is used to treat new patients.
In a new study, published in the Journal of Clinical Investigation, researchers tested the blood of 126 COVID-19 survivors and noticed three important factors.
Scientists said they now know that the sicker a patient is with the virus, the stronger the antibody response seems to be.
The study also shows that the age and gender of blood donors seems to make a difference as well.
Researchers found that older men who were hospitalized with coronavirus were among the strongest candidates for plasma donation.
