Summary

This early-stage study tested a new meningococcal B vaccine in 576 healthy people, from infants to adults. Researchers checked for side effects and measured immune responses, comparing the new vaccine to two already-approved ones. The goal was to see if the vaccine is safe and triggers a strong immune defense.
