Question: As you make viruses that carry the treatment to motor neurons in the body, how can you be sure that the viruses are completely safe and that they don't have any harmful side effects?

Unfortunately, we don’t know if they are completely safe so there is always a risk. However there are thousands of studies using these viruses and we can look at all the results together to get a good picture of whether or not they are safe. We also test these viruses ourselves using human cells grown in a lab to look for any potential side effects. After this step we look how the virus would behave in mice or fish to see if they affect a working multi-organ organism. Even if they work using these experiments we still don’t know for sure.
