Head, Infectious Disease Implementation
BMBS DTMH GDipClinEpid PhD FRACP
Professor Tom Snelling is Head of the Infectious Disease Implementation research team at Telethon Kids Institute's Wesfarmers Centre of Vaccines & Infectious Diseases, and a NHMRC Career Development Fellow.
His research addresses the implementation of health policy and clinical practice, in particular the evaluation of vaccination and other public health strategies to minimise the burden of childhood infectious diseases. This work integrates clinical trials with case-control and cohort studies and disease modelling. His current work is investigating how best to prevent and treat gastroenteritis, pneumonia, pertussis and other lower respiratory infections, and congenital rubella. Tom was awarded a Medical Research Future Fund (MRFF) grant from NHMRC earlier this year and leads this Bayesian Evidence-Adaptive Trial to optimise management of cystic fibrosis.
His work has a strong focus on Aboriginal and international child health. He is also investigating the safety of vaccination in early childhood.

Topical versus systemic antibiotics for chronic suppurative otitis media
Chronic suppurative otitis media (CSOM), sometimes referred to as chronic otitis media (COM), is a chronic inflammation and often polymicrobial infection (involving more than one micro-organism) of the middle ear and mastoid cavity, characterised by ear discharge (otorrhoea) through a perforated tympanic membrane. The predominant symptoms of CSOM are ear discharge and hearing loss. Antibiotics are the most common treatment for CSOM, which act to kill or inhibit the growth of micro-organisms that may be responsible for the infection.

Respiratory failure, multiple organ failure, shortness of breath, recovery, and mortality have been identified as critically important core outcomes by more than 9300 patients, health professionals, and the public from 111 countries in the global coronavirus disease 2019 core outcome set initiative. The aim of this project was to establish the core outcome measures for these domains for trials in coronavirus disease 2019. Three online consensus workshops were convened to establish outcome measures for the four core domains of respiratory failure, multiple organ failure, shortness of breath, and recovery.

The burden of IgE-mediated food allergy in Australian born children is reported to be among the highest globally. This illness shares risk factors and frequently coexists with asthma, one of the most common noncommunicable diseases of childhood.

Combination vaccines containing whole-cell pertussis antigens were phased out from the Australian national immunisation programme between 1997 and 1999 and replaced by the less reactogenic acellular pertussis (aP) antigens. In a large case-control study of Australian children born during the transition period, those with allergist diagnosed IgE-mediated food allergy were less likely to have received whole-cell vaccine in early infancy than matched population controls (OR: 0.77 (95% CI, 0.62 to 0.95)). We hypothesise that a single dose of whole-cell vaccine in early infancy is protective against IgE-mediated food allergy.
