29-year-old haredi (ultra-Orthodox) coronavirus patient who is being treated at Samson Assuta Ashdod University Hospital has gone from serious to severe but stable after receiving several doses of plasma over the weekend donor who recovered from coronavirus, hospital spokesman said The Jerusalem PostOn Friday, “with the help of Minister of Health Ya’acov Litzman and his assistant, an appropriate donor, a resident of Jerusalem, was found,” said MDA director general Eli Bin. MDA took her by ambulance to her blood center before Shabbat. A special team was waiting for him and transferred the plasma units to the laboratories to perform all the required tests and prepare them for transfusion, then, with the approval of the Ministry of Health, the blood units were delivered to Assuta and given to the patient. the man is one of the youngest severe patients in the country. He has several underlying health conditions and was hospitalized in Assuta for about a week and a half. The first patient who recovered from a coronavirus donated plasma on April 1, according to the Assistant Director General of MDA blood services, Professor Eilat Shinar. Since then, some six other patients have donated and, in the past two days, plasma units have been supplied to three different hospitals. A 60-year-old man treated at the Yitzhak Shamir medical center in Be’er Ya’acov also recently received plasma and his condition has also improved slightly. An MDA spokesperson had no information on the third recipient. Shinar explained that plasma is used to create a “passive vaccine”, assuming that those who recover from COVID-19 have developed special proteins or antivirus antibodies in their plasma, which could therefore help sick patients to cope with the disease. Passive vaccination is when you are given these preformed antibodies. An active vaccine, on the other hand, is when you are injected with a dead or weakened version of a virus that tricks your immune system into believing that you have had the disease, and your immune system creates antibodies to protect you. in the first phase of creating this vaccine, by which plasma is frozen and then delivered to hospitals across the country for patients to be treated by transfusion, said Shinar. In the second phase, the goal is to collect enough plasma to prepare the antibody concentrate (immunoglobulin) with which patients will be treated later. MDA has been collecting plasma for over 30 years; thousands of volunteers donate every day. Antibody-containing plasma was used to treat patients with SARS during the 2002 epidemic. In addition, Israel offered similar treatment to patients with West Nile fever. Before being able to donate plasma, a patient must wait 14 days from the time he or she has been confirmed negative for the coronavirus via two separate swab tests. Last month, said Shinar, the FDA approved a similar protocol in the United States.
