A group led by Takashi Igarashi, president of the National Institute of Child Health and Development (NICHD), and Yoshihide Hata, president of Nippon Ham (NIHON HAM), has successfully developed a technology to prevent egg allergy, which is a problem among infants and young children. At present, the research results are from mice (published online in Allergology International on April 18, 2022), but clinical trials have already begun to verify the safety of the technology in humans.
