# The Role of Vaccination in Adult Solid Organ Transplantation: Updated Reviews with Recent Guidelines

## TL;DR

This paper reviews updated vaccination guidelines for adult organ transplant patients to prevent infections due to their weakened immune systems.

## Contribution

The paper provides an updated synthesis of recent guidelines and evidence on vaccination strategies for adult solid organ transplant recipients.

## Key findings

- Timely vaccination before and after transplantation improves outcomes in SOT recipients.
- Comprehensive vaccination planning is vital for reducing vaccine-preventable diseases in immunosuppressed patients.
- Post-transplant booster strategies and serologic monitoring are emphasized in updated guidelines.

## Abstract

Vaccination remains a cornerstone of infection prevention in adult solid organ transplant (SOT) recipients, a population at heightened risk for vaccine-preventable diseases due to chronic immunosuppression and comorbidities. Updated guidelines from the American Society of Transplantation Infectious Diseases Community of Practice (AST IDCOP) and other international bodies emphasize the need for timely and comprehensive vaccination strategies before and after transplantation. This review synthesizes current literature and practice guidelines on vaccination in adult solid organ transplant (SOT) candidates and recipients. Published peer-reviewed studies, clinical trials, and consensus guidelines were evaluated, with emphasis on vaccination timing, safety, immunogenicity, dosing strategies, and serologic response monitoring in the SOT population. Comprehensive vaccination planning before transplantation, combined with appropriate post-transplant booster strategies, remains vital to improving long-term outcomes in SOT recipients. This review provides clinicians with an updated, evidence-based framework for integrating evolving vaccination guidelines into the care of adult transplant patients.
