Here is RFK Jr in August of 2020 providing his prediction of how the vaccine propaganda would play out. He of course nails it, because he understands that this is how they have historically operated.

100% effective, one shot for life

90% effective

70% effective, may need more shots

50% effective, definitely need more shots

20%, more boosters

oh no, there are VaRiAnTs

Just get a shot twice a year for life and enough with the questions!
