The Preclinical Stage Looks At Effectiveness
There is a lot of back and forth for the team of scientists working on a specific vaccine during the preclinical stage. At the end of this stage, their main goal is to have the most effective vaccine possible, as this makes the rest of the process easier. There are several challenges that scientists face when it comes to this stage, from how to conduct the tests to measuring effectiveness.
The preclinical stage will last a couple of years, but some only last about a year. The length of time depends on several factors, from the number of team members to funding. It also depends on how many and what type of testing the scientists focus on.
