Edible vaccines 'to replace jabs'

Japanese researchers have developed a genetically modified rice that could alleviate the sniffles, sneezes and itchy eyes caused by hay fever.

The rice contains an allergy-causing protein, so continuous consumption of the grain could gradually lead to immunity against pollen allergies.

A test group of mice fed the modified grain for four weeks showed fewer allergy symptoms such as sneezing and runny noses than a control group fed normal rice. The researchers will now feed rats and crab-eating monkeys the genetically modified rice to ensure its safety for human consumption.
