'Aspects of Infection 1970'

Chain gave the opening and closing addresses at each symposium, on 'The Semi-Synthetic Penicillins - an 'Introduction' and 'Prospects in Anti-Infective Therapy' respectively. His own conference paper 'Advances in the Understanding of the Mechanism of Penicillin in Allergy' was published in the Proceedings, a copy of which appears at J.111.

During the visit Chain addressed Biochemical/Medical Society meetings on the history of penicillin therapy and an insulin; various dinners and celebrations were also held in his honour.

He returned via Hong Kong and Bangkok where he visited research institutes. Because of his poor health and the protracted nature of the trip, Chain arranged for his family to accompany him and to take the journey in easy stages.
