Mom Donated CCP While Daughter Recovers from COVID-19 (Press Release)


SAN DIEGO (May 13, 2020) – Chula Vista resident and recovered COVID-19 patient Marielena Barajas recently donated convalescent plasma as her 19-year old daughter was fighting for her life in the ICU.

Barajas passed the virus to her daughter, husband and mother-in-law who were all sheltering in place together. While Marielena and her family’s symptoms were bad, her daughter Maya’s symptoms were critical.

Maya was admitted to the ICU at Sharp Memorial Hospital in early April and had to be placed on a ventilator. Maya’s doctor and Marielena made a plan to have Marielena donate convalescent plasma for Maya. But it would take a few days to get through the donation and testing process. Fortunately, San Diego Blood Bank already had an available unit on hand, and it was transfused to her daughter that evening. Marielena went on to pay it forward by donating convalescent plasma to support someone else in need.

According to John Stephan, Sharp HealthCare Senior Blood Bank Specialist, “The patient’s condition, going down very fast, quickly stabilized after the CCP transfusion. The patient’s provider was very grateful that there was another treatment therapy as he had no other options for his patient.”

While COVID-19 has no proven treatment, plasma taken from those who have recovered may help patients currently fighting the virus.

“Maya spent 20 days on a ventilator in the ICU. On the 14th day she received a convalescent plasma transfusion and was successfully extubated that following Friday. Maya is still in the hospital and she is now making steady progress.” said Barajas. “We can thank God, everyone who prayed, all of the doctors and medical staff as well as the San Diego Blood Bank and donors.” 

Individuals can donate convalescent plasma if they have a confirmed positive laboratory test and no symptoms for the last 28 days. People with a subsequent confirmed negative test can donate after 14 days of symptom resolution. People are encouraged to fill out the form even if they have not yet been tested.

To submit contact information to be qualified as a convalescent plasma donor, visit Donors will also need to meet routine donor screening criteria. Marielena is available for video/phone interviews.
