Sasha and Tanya are getting ready for the transplant! Thank you for your help

Sasha and Tanya are always together - on walks, at developmental classes, in hospitals. Tanya is 6 years older, she is more calm and reasonable, and the younger Sasha is fidgety and mischievous. Brother and sister, two wonderful children who were just "unlucky". They were both born with a rare genetic anomaly - primary immunodeficiency. The children's immunity does not work properly, the body cannot resist infections, and the world around them becomes a source of minute-by-minute mortal danger. Both Tanya's and Sasha's lungs were most severely affected by the disease (constant bronchitis, pneumonia and general respiratory failure). The only way to stop the development of complications is to give the children a bone marrow transplant. But before this serious operation, the children's bodies need to be prepared. For this purpose Tanya and Sasha are shown a course of vital substitution therapy with donor antibodies. The family cannot get these medicines from the state yet, it will take months to process the documents. And the children have no time to wait. Dear tubers, please help us to raise funds for these life-saving medicines for the children!
