Types of Vaccines
Vaccines may be based on live, weakened, or killed whole pathogens. Alternatively, they may be based on recombinant proteins with as much immunogenic potential as live pathogens.
Whichever strategy is employed, the challenge is to take the procedure for making vaccines in a research laboratory to a process that can be scaled up and run reproducibly in a manufacturing environment to make tens of millions of doses per year.
GE Healthcare Life Sciences has decades of experience developing tools and methodologies to purify different types of vaccines—including viruses, plasmids, and proteins—using a range of filtration and chromatographic techniques.
