I would presume because flu vaccines etc. require infecting a human with a virus in some form or another, there was plenty of time to ensure engineered viruses do not transmit.

  Is that an accurate comparison? I don't know much about biology so I'm open to be corrected, but I thought that flu vaccines are attenuated or dead versions of the virus, which aren't strong enough to transmit, and RNA vaccines don't include the full virus at all.

    I stand corrected (but FWIW I don't think there's a strong reason for worry unless one is a specialist in this field and has concrete grounds for concern).

  Flu vaccine does not infect you with the flu. It feeds something that looks like carcasses of the flu virus to your immune system to train it.

    Not quite. 1) There are live adenovirus vaccines currently in use (e.g., https://linkinghub.elsevier.com/retrieve/pii/S0264410X16306168 https://linkinghub.elsevier.com/retrieve/pii/S0264410X163061...). 2) People report being sick from inactivated vaccines so those carcasses you mention evidently still trigger symptoms, and according to Wikipedia "most" viral vectors are designed to be incapable of replication so presumably some could transmit. Additionally, at least with Sputnik botched inactivation had been reported (by Brazil, https://www.dw.com/en/brazil-was-there-sloppiness-with-the-sputnik-v-covid-vaccine/a-57425121 https://www.dw.com/en/brazil-was-there-sloppiness-with-the-s...). Frankly if I get symptoms and am contagious then I will consider myself infected for all intents and purposes. In the end, though, we can engineer non-transmittable viruses if warranted, and with proper care we successfully do so. I don't know the approach taken with the cancer-fighting virus in question but I bet proper care had been taken.

      Great job cherry picking tangentially related info off the internet. Those kind aren't in widespread use for the flu. Technically you aren't incorrect but presenting the information like that is disingenuous.

This is almost exactly the premise of “I Am Legend” — the film, at least.

  I think the book deals with a bacteria-based pandemic of unspecified origin. It does have a much, much better plot than the movie tho.

    The alternative, book-correct ending apparently failed with test audiences who failed to identify the doctor as the bad guy. https://youtu.be/Bju1srxOYxo https://youtu.be/Bju1srxOYxo

      oh, I didn't know that ending existed, thanks! It's been a while since I read the book, but it makes sense to me people failed to identify with the doctor as the bad guy at the end of the movie. In the book, we're shown what amounts to a small love story between him and a vampire, and the living-vampires brutalizing the dead-vampires, and finally the doctor. There's a ton of build up to the reversal that the alt ending does not seem to have.
