Which vaccines is a conjugate vaccine?
The most commonly used conjugate vaccine is the Hib conjugate vaccine. Other pathogens that are combined in a conjugate vaccine to increase an immune response are Streptococcus pneumoniae and Neisseria meningitidis”, both of which are conjugated to protein carriers like those used in the Hib conjugate vaccine.
What is the difference between a biologic and a drug?
A biologic is manufactured in a living system such as a microorganism, or plant or animal cells. Many biologics are produced using recombinant DNA technology. A drug is typically manufactured through chemical synthesis, which means that it is made by combining specific chemical ingredients in an ordered process.
What does biologic mean in medicine?
Biologics are powerful medications that can be made of tiny components like sugars, proteins, or DNA or can be whole cells or tissues. These drugs also come from all sorts of living sources — mammals, birds, insects, plants, and even bacteria.

What is the difference between polysaccharide and conjugate vaccines?
In the polysaccharide vaccine, only the sugar part of the bacteria, the capsule, is included as the antigen to stimulate the immune response. “In the conjugate vaccine, it’s actually the sugar joined to the carrier protein,” says Associate Professor Kristine Macartney.
