Conjugate vaccine
Conjugate vaccine
A conjugate vaccine (/kɒndʒʊɡeɪt vaɪˈsiːn/) is a type of vaccine that combines a weak antigen with a strong antigen as a carrier so that the immune system has a stronger response to the weak antigen.
Etymology
The term "conjugate vaccine" comes from the Latin conjugare, which means "to join together". This refers to the joining of the weak antigen with the strong antigen in the vaccine.
Types of Conjugate Vaccines
There are several types of conjugate vaccines, including:
- Haemophilus influenzae type b (Hib) vaccine
- Pneumococcal conjugate vaccine
- Meningococcal conjugate vaccine
Mechanism of Action
Conjugate vaccines work by stimulating the immune system to attack the weak antigen by associating it with the strong antigen. This is done by chemically linking the two antigens together, hence the term "conjugate".
