With different mRNA COVID-19 vaccination in immunocompromised patients, such as kidney transplant recipients (KTRs), solid organ transplant recipients (SOTRs), etc., binding and neutralizing antibodies measurement clearly revealed lower levels, compared to healthy persons.1–5 A number of previous studies demonstrated that KTRs or non-KTRs with renal failure markedly reduced vaccine response, whereas adaptive protocols of mRNA COVID-19 vaccination or alternative adjuvant vaccines is now not known yet.6,7 Whereas protective immunity is further impaired immunosuppressants, thus fully restoring adaptive, cellular immunity and renal function in KTRs cannot occur and increase susceptibility to viral-related malignancies and infections.8–10 After two doses of mRNA-COVID-19 vaccines, the seroconversion rates in KTRs were relatively low that varied from 4% to 57%11,12 and decreased with increasing age.12,13 A recent study demonstrated that everolimus (EVR), a mammalian target of rapamycin (mTOR) inhibitor had a higher seroconversion after mRNA-COVID-19 vaccination among KTRs, in comparison to mycophenolate mofetil (MMF) therapy (Figure 1).14

(AU, arbitrary units; EVR, everolimus; MMF, mycophenolate mofetil).14
In conclusion, immune response, particularly humoral immunity in elderly-post-transplant KTRs after COVID-19 vaccination was associated with EVR treatment and higher seroconversion.
