Preclinical Stage Starts To Look At Testing
Preclinical studies are a huge part of the preclinical stage. These are studies that are conducted before humans, whether it’s on animals or through another means. For instance, cell-culture systems or tissue-culture systems are used during this phase, along with animal testing. If animal testing is involved, there is a specific set of guidelines to follow on the monkeys or mice.
During the studies, scientists are looking at the immune response, safety, and many other factors. Preclinical testing gives scientists an idea of how humans will react to a vaccine. Results often indicated how the vaccine should change or what will make it safer.
