Just marginally.

AFAIK, the bacteria used in this experiment is not related to measles.

However, there is the fact that the US government (all governments really) have repeatedly been found to inflict these kinds of nefarious deeds on their own people AND that they have a tendency to cover up those facts (not all governments are such hypocrites, some are proudly jerks) AND that the general public is often unaware or unwilling to admit it after the fact has been brought to light.

So, this is the kind of thing that reinforces the world view of the AntiVaxer side. Every time you try to reason with them, the label "cover-up" comes to their mind and they just disengage and shut down whatever you are trying to convey. Keep trying long enough, and they will label you as a "sheep" (a member of the willingly unaware public) or a "wolf in sheep skin" (basically, and agent provocateur).

Yep. These bacteria are well known for causing measles after a six-decade incubation period.

no; read the article it's in the 50's

Damn! There goes my "Get those Hippies" theory..

I once drove my car during a flash flood, and wound up flooding the engine and ruining it. When my grandfather found out, he asked "Do you think this Osama Bin Laden guy could have had anything to do with it?"

"No, Grandpa, but thanks for your concern. I don't think there's any mystery here."

No, this happened in a parallel universe with evil governments. No such thing in our universe.
