Purpose of review: This review summarizes the impact of coronavirus disease 2019 (COVID-19) on solid organ transplantation and the most recent data pertinent to disease course and outcomes in this patient population.
Recent findings: The COVID-19 pandemic negatively impacted solid organ transplantation with decreased transplant rates in 2020 but improved in 2021, albeit not entirely to prepandemic levels. Mortality rates of COVID-19 in this patient population continued to be higher, although have improved with more available therapeutic options and vaccination. Immunosuppressed patients were found to require additional vaccine doses given blunted response and continue to be more vulnerable to the infection. Data on immunosuppression alteration when patients have COVID-19 are not available and is an area of ongoing research. Significant interaction with the metabolism of immunosuppression limits the use of some of the new antiviral therapies in patients with organ transplants. Finally, many logistical challenges continue to face the transplantation discipline, especially with pretransplant vaccine hesitancy, however acceptance of organs from donor who had COVID-19 recent infection or died from the infection is increasing.
Summary: Immunosuppressed solid organ transplant recipients continue to be vulnerable to COVID-19 infection with a blunted response to the available vaccines and will likely remain more susceptible to infection.
