I want to know the answer to the following question:
What types of vaccines have been phased out?
All the background I'm provided with is that "Vaccines made from attenuated whole cells or lysates have been replaced largely by less reactogenic, cell-free vaccines consisting of purified components, including capsular polysaccharides and their conjugates, to protein carriers, as well as inactivated toxins (toxoids) and proteins.". Is that enough to answer the question?
