Conjugate vaccines are a type of vaccine that are designed to improve the immune response to certain pathogens. They are particularly effective against bacteria with polysaccharide outer coats, such as Haemophilus influenzae type b (Hib) and Streptococcus pneumoniae. These vaccines work by linking the polysaccharide antigens to a protein carrier, which helps the immune system recognize and respond to the pathogen more effectively.
