How do conjugate vaccines protect babies against bacteria like pneumococcus and Hib?
MedicineVaccines
Quick Answer
They link a weak bacterial sugar coat to a protein, making it easier for the infant immune system to recognize. That creates a stronger, longer-lasting response than the sugar alone.
The Full Story
Some bacteria have polysaccharide capsules that are hard for young children to respond to effectively. Conjugate vaccines solve this by chemically attaching the polysaccharide to a carrier protein, turning it into a better immune target. This approach has been used successfully against Haemophilus influenzae type b, pneumococcus and meningococcus. It was a major advance because it made protection possible in the age group that is most vulnerable.
