Dogs could offer protection against egg allergies in infants
Researchers conducted skin prick tests on more than 5000 one-year-olds, finding that 453 were allergic to egg white.
However, those with pet dogs allowed inside, as well as those with older siblings, were less likely to have an egg allergy by one year of age. The risk of egg allergy decreased with each additional sibling.
The authors said that exposure to microbial products, dogs and microbial stimulation from other siblings could have a protective effect.
Children born to parents from East Asia were at the highest risk
