Transplant candidates and recipients are at increased risk for infections, many of which are preventable by immunization. Patients who are waiting for transplant or post-transplant patients, as well as their household members and healthcare workers have completed the recommended vaccinations before transplantation. Live attenuated vaccines including varicella and MMR are generally not recommended after transplantation, thus protective level of antibodies should be detected before transplantation. Currently, pneumococcal vaccine and zoster vaccines are in clinical trial among post-transplant patients. In this article, we reviewed the guidelines for vaccination in solid organ transplant candidates and recipients and summarize the available literature on the efficacy and safety of vaccines for patients who are scheduled for or who have undergone organ transplantation.
