A former Oxford don who made millions pioneering injection-free vaccines has been trampled to death while out for a morning stroll, Independent reports. 

Brian Bellhouse was walking near the village of Guestling, East Sussex, when he was attacked by “agitated” cattle around 11am on Monday.

Another walker called emergency services after they heard him scream for help near an eleventh-century village church.

Air ambulance paramedics and police performed CPR on the professor but could not save his life.

He was declared dead at the scene later that morning, five miles from his home in Winchelsea.

The eighty-year-old was father-in law to Labour peer and former Minister of Science Lord Drayson.
