A research group led by Professor Satoru Konnai (Graduate School of Veterinary Medicine) and Professor Yasuhiko Suzuki (Deputy Director and Head of the Research Support Division of IVReD) has discovered that administering probiotics to calves enhances vaccine-induced T-cell immune responses.

• Current vaccines alone may not provide sufficient protection against infectious diseases in calves, highlighting the need for new approaches.
• The research demonstrated that administering probiotics to calves can enhance their immune responses to vaccines.
• This strategy may help reduce the use of antibiotics and combat antimicrobial resistance, contributing to healthier calf development and improved productivity.

These findings are expected to offer a new technological option for preventing calf infectious diseases, particularly in cases where existing vaccination programs do not provide adequate protection.
