Summary

This study looks at 200 healthy babies in Iceland to see if antibiotics given early in life change how well vaccines work. Researchers will measure antibody levels in saliva and blood after routine shots, including the rotavirus vaccine. They will also check the babies' gut bacteria to find possible links. The goal is to understand if antibiotics can alter immune responses to common childhood vaccines.
