In view of this situation and of the importance of correct interpretation of antibody profiles for planning preventive measures for COVID-19, we would like to bring the attention of readers to studies that raise concerns about the possible impact of HY upon antibody responses to SARS-CoV-2. To the best of our knowledge, there are no new facts in the scientific and medical literature that indicate that the same mechanism could not operate in HY-treated patients suffering from COVID-19 and negatively impact their SARS-CoV-2-specific antibody responses. As more needs to be learned about the role of antibodies in recovery from and protection against infection with SARS-CoV-2, the impact of HY and other treatment regimens on antibody responses requires systematic evaluation. ./cache/cord-353217-gmc3qrci.txt ./txt/cord-353217-gmc3qrci.txt
