The attempts were indeed inspired by the observations of Edward Jenner who about a hundred years earlier, in 1798, had also noticed the increased reactivity to vaccinia virus occurring in persons who had been previously vaccinated or who had had smallpox.

Protection Induced by Simultaneous Subcutaneous and Endobronchial Vaccination with BCG/BCG and BCG/Adenovirus Expressing Antigen 85A against Mycobacterium bovis in Cattle

The incidence of bovine tuberculosis (bTB) in the GB has been increasing since the 1980s. Immunisation, alongside current control measures, has been proposed as a sustainable measure to control bTB. Immunisation with Mycobacterium bovis bacillus Calmette-Guerin (BCG) has been shown to protect against bTB. Furthermore, much experimental data indicates that pulmonary local immunity is important f...

Probing local innate immune responses after mucosal immunisation

BACKGROUND Intranasal immunisation is potentially a very effective route for inducing both mucosal and systemic immunity to an infectious agent. METHODS Balb/c mice were intranasally immunised with the mucosal adjuvant heat labile toxin and the Mycobacterium tuberculosis fusion protein Ag85B-ESAT6 and early changes in innate immune responses within local mucosal tissues were examined using fl...
