## TL;DR

Epidemiologist who showed HPV vaccination has nearly eliminated cervical cancer in vaccinated English women and leads NHS-Galleri.

## Summary

Peter Sasieni led the 2021 Lancet analysis showing the English HPV vaccination programme cut cervical cancer by 87% in women vaccinated at 12-13, one of the clearest demonstrations of cancer prevention ever recorded, and the modelling that underpins HPV-based and extended-interval cervical screening. He co-leads the NHS-Galleri trial of multi-cancer early detection and directs the Cancer Prevention Trials Unit.
