About Professor John Lambert

Professor John Lambert is a consultant in Medicine and Infectious Diseases with appointments at the Mater Public and Private Hospitals and the Rotunda Maternity Hospital in Dublin. He is a Professor at the UCD School of Medicine and Medical Science. With a career spanning over two decades, Professor Lambert has gained extensive experience in the diagnosis and treatment of a wide range of infectious diseases, with a particular focus on Long Covid, Lyme Disease, HIV, and sexually transmitted infections (STDs).

Professor Lambert began his medical training in New York State, where he gained firsthand experience evaluating and diagnosing Lyme Disease patients. During his time at Johns Hopkins in Baltimore, he contributed to the evaluation of the then soon-to-be-licensed Lyme Vaccine and served as a member of the Data Safety and Monitoring Board for this vaccine. Over the past 40 years, he has continued to diagnose and treat Lyme infections, managing cases contracted both domestically within Ireland, the UK and internationally.

Throughout his career, Professor Lambert has made significant contributions to HIV research, focusing on drug studies, the management of HIV and hepatitis C co-infection, and therapeutic drug monitoring in pregnancy. His work includes over 10 book chapters and more than 80 peer-reviewed articles on infectious diseases, vaccines, HIV, and STDs, establishing him as a leading authority in his field.

Our Approach to Long COVID Treatment:

Professor Lambert consults patients at his private clinics in Dublin, Ireland, and Edinburgh, UK

The main focus of Long Covid treatment needs to be 'neuro rehabilitation', with training the brain to repair the damage done and taking medicines and supplements that will decrease the inflammation and repair the immune damage done by the COVID-19 virus.

Long Covid is a term used to describe those who are still unwell at least three months following their acute COVID-19 infection. The symptoms are widely varied, as the Long Covid virus attacks many parts of the body. However, the underlying mechanism appears to be brain and nerve inflammation, and most patient symptoms are a function of the damage to the nervous system. With time, some people improve, but many with Long Covid, up to thirty per cent in some studies, including studies we have done ourselves at our Long Covid Clinic in Dublin, have persistent pain syndromes, brain fog, head pressures, concentration problems, energy problems, and mood problems. This can be mild or can be debilitating.

I have a lot of confidence in Prof Lambert who has a good grasp of the issues around long covid. On my first follow-up today he updated his initial protocol to adapt to my responses to the original regime, so I am looking forward to being rid of this horrid condition before too long.
