In the press conference of 12 February 2026, Professor KY Yuen in his capacity as the Director of the Centre of Virology, Vaccinology and Therapeutics (CVVT) delivered an academic talk about a novel scientific approach which leads to the discovery of compounds or extracts which inhibit the release of toxin by Staphylococcus aureus without killing the bacteria. This approach would reduce the risk of induction of antibiotic resistance and disruption of the normal microbiome of human.

Prof Yuen wishes to clarify that he has never promoted the use of any drug for the treatment of atopic dermatitis at any time. His role was all along academic for the popularisation of translational science. Based on HKUMed's understanding, Prof Yuen has not taken advantage of his professional capacity as a medical doctor to promote the use of any medical products or health claim substances for the treatment of atopic dermatitis during the press conference. 

Meanwhile, Prof Yuen does not hold any equity interest in CVVT, which is owned by HKU.

We kindly request the removal of any posts that could be misunderstood or that might create a false impression suggesting otherwise.
