Abstract

Objective: This study aimed to evaluate the efficacy and safety of solid organ transplantation recipients inoculated with an inactivated COVID-19 vaccine.

Methods: We retrospectively analyzed the antibody levels and related adverse events of non-transplantation subjects and solid organ transplant recipients, both pre-transplantation (individuals awaiting organ transplantation) and post-transplantation (individuals who have undergone organ transplantation), who received inactivated COVID-19 vaccines from February 2021 to July 2022.

Results: The study included 38 pre-transplantation vaccination group, 129 post-transplantation vaccination group, and 246 non-transplantation group. The antibody titer was assessed monthly within the period of 1-12 months after the last injection. The antibody-positive rate among the three groups were 36.84, 20.30, 61.17% ( < 0.05). The antibody-positive rates among three groups with one, two doses vaccine were not significantly different ( > 0.05), but were significantly different after three doses ( < 0.05). The antibody titers among three groups were significantly different after two doses ( < 0.05). Adverse reactions occurred in six transplant recipients, which were relieved after treatment, and not in the non-transplantation subjects.

Conclusion: Inactivated COVID-19 vaccine is safe and effective for solid organ transplantation recipients, at least two doses of which should be completed before organ transplant surgery.
