Immunocompromised patients struggle to adequately clear viral infections, offering the virus opportunity adapt immune system in host. Here we present a case study of patient undergoing allogeneic hematopoietic stem cell transplantation with 521-day follow-up SARS-CoV-2 infection BF.7.21 variant. Virus samples from five time points were submitted whole genome sequencing. Between first detection and its clearance, patient's population acquired 34 amino acid substitutions 8 deletions coding regions. With 11 receptor binding domain virus' spike protein, 15 times more abundant than expected for random distribution this highly functional region. Amongst them S:K417T, S:N440S, S:K444R, S:V445A, S:G446N, S:L452Q, S:N460K, S:E484V at positions that are notorious their resistance-mediating effects. The substitution patterns found indicate ongoing adaptive evolution.
