Background: It is currently not well described if a two-dose regimen of a Covid-19 vaccine is sufficient to elicit an immune response in solid organ transplant (SOT) recipients.
Results: A total of 80 SOT recipients completed a two-dose regimen with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) messenger RNA vaccine. Only 35.0% (n = 28) were able to mount a positive IgG immune response 6 weeks after the second dose of vaccine.
Conclusion: This emphasizes that SOT recipients need continued use of personal protective measures. Future studies need to closely examine the cellular immune response in patients with compromised antibody response to Covid-19 vaccination.
Keywords: Covid-19; immune response; solid organ transplant recipient; vaccine.
