adjuvant
Pronunciation: AD-juh-vuhnt
A substance added to vaccines to enhance the immune response, particularly important in pediatric vaccination schedules.
Full Definition
An immunopotentiating agent added to vaccines to stimulate and enhance the immune response to the target antigen. In pediatric immunology, adjuvants are crucial components of childhood vaccines, helping to achieve protective immunity with lower antigen doses and fewer immunizations. Common pediatric vaccine adjuvants include aluminum salts, and newer adjuvants are being developed to improve vaccine efficacy in infants and immunocompromised children.
Usage
Usage note: In vaccine contexts, always refers to immune enhancers, not the cancer treatment meaning of 'adjuvant therapy'.
In Context
- "The aluminum-based adjuvant in the DTaP vaccine helps ensure robust immune responses in infants." — vaccination guidelines
- "Novel adjuvants are being studied to improve vaccine immunogenicity in immunocompromised pediatric patients." — clinical trial protocol
