Once the elderly, chronic diseases and tumors are infected by the new coronal virus, the risk of severe illness and death is significantly higher than that of ordinary people. Professor Ma Jun, director of the Harbin Hematology Institute, emphasized that among the above -mentioned new crown infection, high -risk groups, patients with hematoma are particularly fragile, and the post -infection is severe and the mortality rate is higher.

Lymphoma, leukemia, multiple bone marrow tumors, and bone marrow hyperplasia syndrome (MDS) is the most common type of hematological tumor in my country. About 400,000 newcomers are issued each year. This is not a small number. Ma Jun analyzed that blood tumors were mainly B -cell tumors. In the process of chemotherapy, most of these antibodies cells were killed. Therefore, facing the invasion of viruses, the human body was difficult to produce effective immunity.

New crown vaccines can activate the immune system in the human body and produce active immune response, which is one of the effective measures to fight virus infection. However, during the progress of the disease, patients with hematological tumors do not recommend vaccination because the B cells in these patients are at a lower level, and the antibodies produced after vaccination are relatively small. Consider vaccination.

According to Ma Jun, the damage to the immune system of patients with hematological tumors may also cause a series of complications such as viral pneumonia, mold infections, cerebral hemorrhage, pulmonary bleeding, and digestive tract hemorrhage that may occur, thereby aggravating the illness and even death Essence

Clinical data show that after leukemia, lymphoma, osteoma, and MDS patients infected with new coronary virus during the progress of the disease, their risk of death was 5 times that of physical tumors and 12 times that of normal people. Therefore, Professor Ma Jun also suggested that if patients with hematological tumors are infected with new crowns, in addition to participating in the treatment of treatment, the hematologists should be considered as soon as possible to increase the success rate of treatment by multi -disciplinary joint diagnosis and treatment.

Prevention is better than treatment. In addition to reducing public health defense measures that reduce external contact, patients with hemioma must also actively improve their own immunity. "Diseases and chemotherapy consumes patients' immune cells in the body and cannot produce antibodies. We can give patients' foreign aid ' -neutralized antibody drugs, and passively immune to fight possible viruses." Professor Ma Jun introduced.

At present, the international medical field has the clinical practical experience of 24,000 physical tumors and more than 3,000 patients with hematological tumor patients, which proves that antibody therapy can reduce the complications of new crown infections and infection, and extend the total time of patient survival. On April 5, 2022, the National Comprehensive Cancer Network released the guidelines for the new crown vaccination guidelines for tumor patients "NCCN COVID-19 VACCINATION GUIDE for People with Cancer". Among them Priority application has been proven to have been proven to have anti -clone antibody drugs.
