The advantage of passive immunization is that you do not need to develop a cure COVID-19 in the laboratory – this work already makes the immune system of the donor.
In Canada, more than 50 medical centers have joined forces in a large-scale project for passive immunization of critically ill COVID-19 blood plasma of those patients who have recovered from the disease. This was announced at the University of Montreal.
We are talking about the treatment using convalescent blood serum of recovered patients.
It is known that when the soldier is recovering, his blood have antibodies – is produced by immunity from re-infection. Doctors will wait two weeks after symptoms disappear before you collect plasma from recovered patients.
Previously, the efficiency of this method against COVID-19 demonstrated on small groups of patients now in Canada hope to conduct more extensive.
“The advantage of passive immunization is that you do not need to develop a cure COVID-19 in the laboratory – this work already makes the immune system of the donors,” – said in the message.
The challenge now is to urgently establish an infrastructure for collecting plasma and to carry out parallel trials in different centers.
Epidemiologist called work treatment method COVID-19
According to the initiators, is “a promising approach based on old knowledge”, which was used during major epidemics prior to the advent of vaccines, including during the Spanish flu pandemic nearly 100 years ago. Then it was reported to reduce the mortality by 75%. One of the advantages of passive immunization is that the number of potential donors increases with the progression of the pandemic.
If the results of a large-scale study “hard”, then hospitalized “immediately offered” to participate in the project for the donation of plasma. Similar studies are now conducted in some other countries – China, USA, Russia, France, Turkey.
According to recent reports, the world recorded more than 1.8 million cases COVID-19, died over 114 thousand people, recovered more than 423 thousand. In Canada infected with more than 24 thousand people died 717.
