Adam read Medicine and Neuroscience at Cambridge University before completing his clinical training at University College, London. After specialist training in Paediatric Allergy in 2006, he spent 9 years as clinical lead for Allergy (Adult & Paediatric) at Guy’s & St Thomas’ Hospitals, London – one of Europe’s largest specialist Allergy services, recognised as an International Centre of Excellence by both the World Allergy Organisation and GALEN (European Asthma & Allergy Network). After 3 years as Clinical Director for Specialist Ambulatory Medicine, he took up the post of Deputy Medical Director (Commercial) for Guy’s & St Thomas’ Hospitals NHS Foundation Trust in 2018 until 2023.

Adam chaired the UK Department of Health National Care Pathway for Food Allergy in Childhood and was a member of the National Institute of Healthcare and Clinical Excellence (NICE) clinical guideline development group for the assessment and diagnosis of food allergy in children. He has been an expert committee member on two MHRA specialist groups and a NICE Health Technology Appraisal and was appointed a NICE non-specialist guideline chair in 2021. He was senior author of the iMAP (International Milk Allergy in Primary Care) guideline, which was awarded the Allergy UK Innovation award in 2018. He previously represented Paediatric Allergy on the NHSE Specialist Paediatrics Clinical Reference Group and chaired the Paediatric Committee of the British Society of Allergy & Clinical Immunology (BSACI). He was elected as BSACI President, the first Paediatrician to hold this position, from October 2018 until 2021, after which he took on the role of Chair of the National Allergy Strategy Group from July 2022.

Adam received the William Frankland Award for Outstanding contribution to Allergy from the British Society of Allergy & Clinical Immunology in 2015 and a National Clinical Excellence award from the UK Department of Health in 2016 and 2020. In 2024, Adam became only the second person to receive the BSACI Fellows Award in recognition of outstanding contribution to clinical allergy. In 2025, Adam was awarded an OBE for services to Paediatric Allergy as part of the King’s Birthday Honours list.

He also has a very active allergy education focussed education account on Instagram @dradamfox .
Adam’s private practice, Allergy London was awarded 'Best Allergy Clinic - London' in the 2019 Global Health & Pharma Private Healthcare Awards and Best Allergy Testing Specialists in the 2020 Private Healthcare Awards. He was also recognised by Doctify for 'Excellent Patient Experience' in 2018 and was one of a small number of specialists to receive the ‘Top Doctors award’ in 2018 and again in 2022 from Top Doctors website, voted for by other doctors, asked to nominate who they would choose to go to. He was also included in ‘The Tatler Doctors List’ (2013 & 2026) of the best UK private medical consultants.
Together with Profs Gideon Lack & George Du Toit, he established The Allergy Centre of Excellence to offer cutting edge diagnostics and treatments not otherwise available in the UK. Initially, this was operated at Great Ormond St Hospital and in 2021, having initiated the first patient in the world, outside of the US, on Palforzia (the first licenced food allergy desensitisation product) it became Europe’s leading provider of this treatment. Following successful introduction of oral immunotherapy for numerous other food allergies, the centre moved to its new premises, at 10 Duchess Street, in London’s prestigious Harley Street Medical District.
Professor Fox ensures that all problem foods are correctly identified using allergy tests such as skin prick testing, specific IgE blood testing, atopy patch testing or provocation challenges. Common allergic problems such as eczema and asthma, which often accompany food allergy, are also identified and treated. When an allergen is identified and excluded from the diet, Prof. Fox is able to offer advice on substitutes for essential nutrients and on how to recognise and deal with any subsequent reactions that may occur accidentally, as well as offer desensitisation (food OIT) for select allergens such as milk, egg and peanut.
Eczema affects 15-20% of school children, in some cases with a significant impact on quality of life. Prof. Fox combines a detailed clinical history with allergy testing to identify and exclude food or environmental allergens, helping to improve eczema and lessen the need for steroids.
Over 1 million children in the UK suffer with asthma. The identification of allergens, used in conjunction with other treatments, can lead to effective control of symptoms. Prof. Fox uses the latest monitoring techniques such as computerised spirometry and exhaled nitric oxide measurement. He is at the forefront of the development of sublingual immunotherapy (a desensitisation process where drops are placed under the tongue daily to lessen an allergic reaction) and anti-IgE therapy for children whose symptoms do not respond to conventional therapies.
Hay fever (allergic rhinitis) is a distressing and irritating condition, affecting approximately 15% of children. It can adversely affect quality of sleep and impact on school life. Following correct identification of the causative allergen, hay fever can be treated with safe medication. There are children for whom this approach is less effective, and in these cases Prof. Fox is now able to offer the new specialist treatment of sublingual immunotherapy. This is available for grass and tree pollen, dust mite, cat, dog and horse allergies.
As one of the UK's few accredited specialist paediatric allergists, Prof. Fox does not look to treat a condition in isolation but looks beyond the presenting problems to consider their underlying cause. He aims to treat the child as a whole, considering how the symptoms and the treatment of one condition will impact those of the others. Prof. Fox work in the UK's largest NHS children's allergy service, Guy's and St Thomas and ongoing involvement in academic medicine allows him to bring the most up to date specialist treatments to his patients before they are available outside of the specialist arena.
Principle Investigator for Guy's & St Thomas' Hospital for 2 international multicentre trials: - GAP study - using desensitisation to prevent the development of asthma in high risk allergic children - PAICE study investigating role of pre/probiotics in accelerating tolerance in milk allergic children.
Prof. Adam Fox's skill and experience has led to him speaking about his field on a number of different platforms. These include on national television, research papers and peer reviewed journals. You can find out more about Prof. Fox's work with the media at www.allergylondon.com/press.
