1. Our Services
We offer a range of services designed to diagnose, treat, and manage infectious diseases and immune system disorders in children and adolescents.
Diagnosis and Management of Paediatric Infectious Diseases and Immunodeficiencies for hospitalised children:
- We manage children with bacterial, viral, fungal, and parasitic infections.
- Our expertise includes severe infections such as sepsis, meningitis, bone and joint infections, etc as well as HIV, tuberculosis, congenital infections and infections in the immunocompromised host.
- We work jointly with colleagues from other specialities at St. George’s University Hospital (general surgery, neurosurgery, ENT, ophthalmology, trauma and orthopaedics, Allergy, Respiratory, Haematology/Oncology, Dermatology, PICU and NICU, Adult Infectious Diseases and Microbiology at SGH, Adult Immunology Team at St Heliers).
Immunodeficiency and Vaccine Services:
- Comprehensive diagnostics for primary and secondary immunodeficiencies.
- We manage the full spectrum of primary and secondary immunodeficiencies, and immune‑dysregulation disorders. We do not provide gene therapy or bone‑marrow transplantation on site, but work closely with quaternary centres and offer ongoing local follow‑up for these patients.
- Home care service for patients requiring immunoglobulin replacement therapy.
- Vaccination advice for children with immunodeficiencies, those who are on immunosuppressive therapies, or who have had previous reactions to vaccines (in close collaboration with paediatric allergy).
- We are the reference centre in South West Thames for SCID screening.
- We undertake research focused on immunological conditions.
- We do not deliver dedicated immunology subspecialty training, but our Paediatric Infectious Diseases trainees attend immunology clinics to gain supervised clinical exposure.
Travel and Tropical Medicine:
- Pre-travel consultations for vaccinations and advice on travel-related infections.
- Post-travel assessments for children returning with fevers or other symptoms of tropical diseases, such as malaria or dengue fever.
Antimicrobial Stewardship and Infection Control:
- Our team works to ensure the appropriate use of antibiotics and other antimicrobial treatments within Paediatric at St. George’s University Hospital.

4. Education and work experience
We are actively involved in providing training opportunities for healthcare professionals and are one of several national training centre for Paediatric Immunology and Infectious Diseases (PIID) in the UK.
Undergraduate
We collaborate closely with City St Georges University of London by supervising SSC (student selected component) placements and other undergraduate medical student research and healthcare service evaluation projects, offering insight and encouraging interest in PIID.
Postgraduate
Our unit actively collaborates in the training of resident doctors. Our day-to-day clinical service is supported by a team of resident doctors one F1, three paediatric ST1-ST4 trainees and two to three ST5-ST7 trainees), led by a consultant. Our resident doctors are involved in both inpatient and outpatient activities as well as in clinical governance, audits and research projects. Our ST5-7 trainees are drawn from both the PIID sub-specialty training programme and from the general paediatrics training pathway.
We support Integrated Academic Training (IAT) through offering regular National Institute for Health Research (NIHR)-funded opportunities for Academic Clinical Fellowship (ACF) and Clinical Lecturer (CL) posts. These posts provide structured pre-doctoral and post-doctoral academic training and experience at City St George’s, University of London, alongside clinical training in the trainee’s specialty (e.g. general paediatrics, PIID, or neonatology). These posts are advertised annually and subject to competitive entry. The posts aim to train future academic leaders in paediatrics who are capable of developing further centres of excellence. City St George’s University of London offers a comprehensive programme of research skills training for staff, and George’s Academic Training (GAT) supports ACFs and CLs through mentoring, formative appraisal, and networking events. Integrated academic trainees at St George’s have the opportunity to study for a Postgraduate Certificate in Healthcare and Biomedical Education, Postgraduate Certificate in Genomics, or a Postgraduate Certificate in Healthcare Research Skills and Methods.
We offer an annual position for a Paediatric Infectious Diseases Clinical Fellow. This opportunity is open to senior trainees or early-career consultants from the UK and overseas who wish to expand their knowledge in this field for 6 or 12 months. For more information please, contact our secretary (archana.pydegadu@stgeorges.nhs.uk).
We accept overseas Observers. This role is particularly designed for overseas doctors in training who are seeking experience in a tertiary care Paediatric Infectious Diseases Unit in the U.K. Clinical observers are organised so there is a maximum of one trainee during the rotation. This observer is involved in the inpatient and outpatients review as well as an audit/guideline review. For more information please, contact our secretary (archana.pydegadu@stgeorges.nhs.uk).

5. Research
We are involved in cutting-edge research to improve the diagnosis and treatment of infectious diseases and immunodeficiencies in children. Our Unit is closely related to the Centre for Neonatal and Paediatric Infection (CNPI), at City St George’s University of London which is an internationally recognised centre leading global Paediatric Infectious Diseases Research. The CNPI includes a research portfolio comprising a variety of projects and studies in children, with a focus on the epidemiology and treatment of vaccine-preventable diseases (Professor Paul Heath, Professor Shamez Ladhani, Dr Sarah Prentice), global antibiotic resistance and prescribing (Professor Mike Sharland and Dr Julia Bielicki), global neonatal health and maternal vaccination (Professor Kirsty Le Doare, Dr Kostas Karampatsas, Dr Sarah Prentice), congenital infections, health inequalities and migrant health (Dr Nuria Sanchez Clemente), and on infant feeding, gut microbiome, and antimicrobial resistance (Dr Rosie Crane).
