Conjugate Vaccines

A conjugate vaccine is a type of vaccine that helps the body’s immune system recognize and better fight infections from bacteria by fusing an antigen from the bacteria to a protein. This combination causes the body to produce both a humoral (B-cell) and a cellular (T-cell) immune response, thus providing more effective protection. Conjugate vaccines are used to prevent illnesses such as meningitis, pneumonia, and sepsis, and are especially important for preventing serious infections in infants and young children. They are also used to protect against drug-resistant bacteria, which are a growing public health concern.
