Exactly why vaccinations should never be compulsory. This puts us a single step away from genocide if bad actors have control of the process.
Even precisely TARGETED genocide.. (If this theory is plausible.. I did come up with it all by my own self just now, so possibly not..)
You could just say "Whites need vaccine #2, Asians need vaccine #3, and Hispanics need vaccine #1..
Then you could just release the virus #2 that you have compromised all the Whites to, and BAM targeted racial genocide..
Or you could just give everyone in for example Columbia vaccine #6, then wipe them out with corresponding virus #6 and then be like "Woah! What happened here?"..
What if you could make a virus that you know that everyone in the USA, or Russia, had vaccines that would compromise them to?
You could wipe USA out if you could make a virus that was super effective against those who got the common flu vaccine in USA..
