At the time of give plasma, a new problem appears for blood banks in the world with the arrival of vaccines against Covid-19.
–
The reason for this is that people who are vaccinated will not be able to donate their plasma, which means that less will be available to treat those affected.
–
This is because the vaccines cause antibodies from the peak and for the convalescent plasma, with which patients are treated, they need those of the coronavirus nucleocapsid protein.

According to the US media, one in four people hospitalized with Covid-19 in the world requires a convalescent plasma transfusion (from individuals who faced the infection).
Blood donated by those who have recovered from Covid-19 has antibodies that block the activity of the virus in the recipient patient.
Transfusion of these fluids has been shown to boost the patient’s ability to fight the virus. For this reason, plasma therapy remains key in the recovery of many patients.
“Currently, plasma therapy in SARS-CoV-2 has two types of results: studies that highlight moderate benefits and others that do not register changes. This treatment does not influence mortality, but it does influence the recovery of the patient “, he told Tec Review Dr. Carlos Gabriel Díaz Olachea, clinical director of the Laboratory and Blood Bank of the TecSalud System.
