My mother died a year ago from multiple myeloma and And I can tell u that she would have much preferred measles.

It's not the injecting large quantities of virus that poses a risk, it's genetically modifying viruses and then exposing people to them that is risky.

I would hope that quarantine procedures around any human made-or-modified virus would be quite strict to avoid something unwanted making it's out of the lab.

Don't take it as a very profound observation. I just meant that a cure for cancer from a genetically-engineered variant of the measles virus is the way that all the population in the US ends up turned into zombies in that movie.
