Amplification curves and cycle threshold (Ct) values were not mentioned in patient 1 and 3. ** We administered four units of high-titer post-vaccine Omicron COVID-19 convalescent plasma in all patients (two units on day 1 and two units on day 2). *** BAL SARS-CoV-2 RT-PCR follow-up after convalescent plasma administration were not performed in any patients regarding the complete recovery.
