The first three COVID-19 patients treated with a new Israeli “passive vaccine” were released home from the hospital, Hadassah Medical Center in Jerusalem said Thursday.
Passive immunization occurs when a recovered patient gives antibodies to a current patient while active vaccines occur when a patient is inoculated with a dead or weakened strain of an actual virus, prompting the body to generate antibodies.
The hospital has been collecting plasma donations from coronavirus patients in the ultra-Orthodox community, Israel’s hardest-hit population, for the past three months, Hadassah head Prof. Zeev Rotstein said.
The donated plasma is being administered to COVID-19 patients who develop pneumonia and “for now, we are very encouraged.”
“The Hadassah hospital is involved in the clinical research on the new Russian vaccine.
