Biography
Katrina Pollock is Associate Director (People and Culture) at the Oxford Vaccine Group and an MRC Clinician Scientist in Vaccinology. She is also an Honorary Consultant in Sexual and Reproductive Health at Oxford University Hospitals NHS Foundation Trust.
She leads the national MRC/UKRI LEGACY IIII Network (Lymph nodE single cell Genomics AnCestrY: immunity, infection, inflammation and immunisation), bringing together researchers across the UK to advance understanding of lymph nodes, one of the least well characterised human tissues.
Katrina studied medicine at Newnham College, University of Cambridge, and Imperial College London, before completing specialty training as a clinician scientist in genitourinary and HIV medicine. She went on to earn a PhD in immunology and a lectureship, leading a series of first-in-human vaccine trials, including novel COVID-19 vaccines at Imperial College London. Her contributions during the pandemic were recognised with an award for substantial and exceptional achievement.
Her research focuses on the lymph node response to immunisation, uncovering mechanisms of vaccine immunogenicity in diverse populations to inform the development of next-generation vaccines. She is committed to involving research participants and the wider public at every stage, ensuring that innovative science translates into real-world benefit.
