A couple of days ago, I downloaded from a local (usually reliable) BBS a
copy of Vaccine that alleges to be "Vaccine version 1.0.1".  It came
without any significant documentation.

Compared to the 1.0 version I had been using:

			Size in bytes	Creation date
Vaccine 1.0		11,875		March 21, 1988
Vaccine 1.0.1		11,967		December 21, 1988

There appear to be no significant differences in the informative
messages printed by these two versions.

I can imagine that the 1.0.1 version might be one of two things:

1) It could be a legitimate update to 1.0, which fixes a bug [perhaps
   Vaccine's habit of causing system crashes when an infected
   application is launched?]

2) It could be a trojan-horse modification of Vaccine 1.0, with some
   modifications that would permit infection by some as-yet-unknown
   virus at a future time. 

Does anyone out there have any information about this alleged update to
Vaccine?
