Two hundred years ago - in May 1796 - Edward Jenner carried out a pion
eering feat in the history of 'clinical investigation' which not only
paved the way for the eventual elimination of one of the world's most
terrifying infections (variola), but also heralded widespread vaccinat
ion campaigns and the foundation of the discipline of clinical immunol
ogy. Vaccination superseded the formerly used technique of variolation
which had been introduced into England by Lady Mary Wortley Montague.
Under-recognised is the fact that the first clinical trial(s) of this
new development were carried out under the supervision of William Woo
dville at the St Pancras Smallpox Hospital (situated at Battle Bridge
- now King's Cross); this work was crucially important in the 'vaccina
tion saga' and deserves far greater acceptance than is currently the c
ase.
