Vaccines may be given in food in the near future

October 24, 2017

The success of a human trial at Sir Charles Gairdner Hospital is seen as a major step towards revolutionising a multi-billion dollar global vaccine industry. Results from the trial of 30 patients, released at the fifth World Vaccine Congress Asia in Singapore, showed the strains had no ill effects on the stomach while still producing an immune response. ???We can have a repertoire of strains, some which will stay in the body short term, maybe months, so can be good for things like seasonal flu, while others can stay in the body long term to protect against diseases like malaria. We know about half the people in the world carry Helicobacter without it causing any symptoms so we were always confident this approach was safe. The good thing is that nearly everyone we gave it to became 'infected' so the vaccination rate was very high,??? Professor Marshall explained.

Dr Marshall and the privately owned company Ondek have already patented and genetically analysed the tweaked strains. Ondek was seeking approval for another round of clinical trials in which a flu virus gene would be attached to bacteria.

The technique could deliver insulin to people with diabetes or be used in immunotherapy vaccines for asthma he added. Vaccines could also be put in the drinking water of cattle to prevent foot and mouth disease.
