Believe me, one of my goals in life now is to live long enough to see those responsible for what is happening right now suffer for what they're doing.

However now more than ever is the time to decide what one's goals are, and to act with purpose toward those goals. We cannot afford to make very many superfluous moves. What's done is done for your friend for this battle, but there will be many more battles to fight.

If your primary goal is to not be injected, and you don't really care about making a political statement (or you aren't in a position to make one), then probably the simplest option is to simply bribe the nurse giving the injections to shoot it into the garbage can and sign the form saying you got one. Or the HR lady who checks the "passport" and checks your employer's form saying you got one. Or forge the "passport" itself.

The corollary to what I just said above is perhaps your friend in the future will be in a position where he can help a fellow traveler as stated above, and perhaps he can consider how he might make that fellow travel's journey a bit easier than his own was, so to speak.

However one should probably not assume this strategy will work long-term, and if someone goes that route they should probably treat it as a short-term solution to the longer term problem and use the time it buys them to find a longer-term solution.

Doing what your friend did was never going to be anything but be a political statement, the outcome of which was a loss either way it was likely to turn out.
