To the Editor, Heart transplant recipients are at increased risk of adverse outcomes from SARS-CoV-2 infection. 1, 2 They also experience prolonged infectious periods in which they may serve as a reservoir for developing more transmissible and pathogenic strains of SARS-CoV2. Emerging viral variants may be less likely to be recognized and inactivated by existing acquired immune responses. 3 The clinical impact of COVID-19 on heart transplant (HTx) recipients during the surge of the SARS-CoV-2 Omicron variant and the introduction of vaccination in this population remain unclear. Currently, Argentina is among the 11 countries with the highest COVID-19 contagion rates in the world. 4 The objective of this report was to evaluate the incidence of COVID-19 and the clinical outcomes in heart transplant patients before and after they had a complete vaccination scheme.

We carried out a single-center prospective cohort study from March 2020 to January 27, 2022 at a high cardiovascular complexity hospital in the City of Buenos Aires, Argentina.

We included 59 heart transplant adult patients. Since the beginning of the pandemic, telephone or in-person follow-up visits were carried out to evaluate if they had COVID-19 diagnosis and clinical outcomes, and further, to assess their vaccination status.
