Still out there

Yeah it's not that simple, wikipedia has a good summary:

Advocates of final destruction maintain that there is no longer any valid rationale for retaining the samples, which pose the hazard of escaping the laboratories, while opponents of destruction maintain that the samples may still be of value to scientific research, especially since variants of the smallpox virus may still exist in the natural world and thus present the possibility of the disease re-emerging in the future or being used as a bio-weapon.

Exactly, know your enemy, especially if you think you have defeated it.
We are about to see all the "defeated" diseases make a comeback due to politicians interfering in preventative healthcare. All in order to drive up revenue for big pharma and corporate healthcare from the increase in sick people.

Keep the virus data in a computer where it can't escape from.
- Computers can spread viruses too ☝️🤓
- We're not to the point that that's possible.
- ... Thanks, I guess? At least the very suspiciously bot-like accounts approve of me?

This would kind of make sense if Isildur had taken the ring and tried to disassemble it and learn how its various magic effects worked, in order to extend life without the downsides.

The amount of things we've learned from the field of virology is fucking nuts.

- Bot account right there

It would be horrible in real life but I thought a funny intro to a post apocalyptic movie would be a person giving a tour of a bio lab to college interns and...

"through our studies we have learned to increase the transmission rate and the death rate of the small pox virus. The downside is we had to mix it with rabies so the infected tend to get aggressive and lose there ability to rationalize their thoughts. Don't worry though, there is only this one vial of it in the entire world... these gloves are quite slippery.. Oops"

No I think it would be better in real life. To scare interns. Not actually develop the megapox.

Vector Institute would be a sick name for a bio-terror group in Shadowrunner

they've gone M.A.D.

SARS CoV 3: 'Murica Boogaloo

Don't worry, there are multiple layers of protection. So far they're doing great, even Vector, even now: https://iris.who.int/server/api/core/bitstreams/50484602-5796-40de-9151-b41f1ffe83cd/content
