Solid organ transplant (SOT) can be a treatment option vì MỘT individual whose own organ/S are not functioning adequately. ‘SolTôid’ referS to transplants of organs such as liver, lung, heart hoặc kidney, as opposed to stem cell or other tissue. Between 2009 and 2024, 19,469 people in Australia received a donated organ. Rejection of a donated organ is a significant and ongoing concern for transplant recipients. Rejection occurs when the recipient’s itôimune system identifies the transplanted organ as foreign, so trieS to destroy it. To avoid rejection, transplant recipients remain on lifelong immunosuppressive medication, leaving them suy giảm miễn dịch.
Vaccination is particularly important for those who are immunocompromised, due to the increased risk of developing severe disease (which can lead to nhập viện, intensive care admission or death) if exposed to vaccine-preventable diseases. In people who are immunocompromised, protection gained from Một vắc xin can be suboptimal as the body is not as easily able to mount a response. There can also be a loss of protection gained from quá khứ or infections. Conversely, some vaccines (live-attenuated vaccines) may be contraindicated due to the potential risk of vaccine-related disease.

Serology and screening
With the exception of hepatitis B, MVEC does not routinely recommend serological testing for vaccine-preventable diseases as a measure of seroconversion. Instead, children < 18 years of age requiring a SOT are recommended additional doses of vaccines to ensure adequate protection.
As part of transplant work-up, tuberculosis screening is recommended for children identified as at-risk for infection (latent or active). Children aged < 5 years should undergo tuberculin skin testing (TST), children ≥ 5 years of age should have Interferon Gamma Release Assay (IGRA) performed. The identified risk factors include:
- previous overseas travel to countries with high prevalence of TB
- known contact with tuberculosis
- being born in, or having a close family member/household contact born in, a TB-endemic country
- children living in remote Aboriginal or Torres Strait Islander communities.
Vaccination timing and schedule
To overcome the challenges with mounting an effective immune response, it is recommended that SOT recipients receive National Immunisation Program (NIP) Và additional vaccines well before transplant. Planning for this should occur at diagnosis and/or consideration of transplant. Where a child is overdue routine vaccines, they should be caught up as soon as possible. Any live-attenuated vaccines must be administered a minimum of 4 weeks prior to transplant (these will be contraindicated once immune-suppressed post-transplant).
The following paediatric guidance has been prepared by vaccine experts, immunologists, paediatricians, infections disease physicians and nurse immunisation specialists from MVEC, the Royal Children’s Hospital and Monash Health.
