He says he did. So either he's telling the truth and he got it, he's lying and he didn't get it, or someone switched it without his knowledge. If he's lying and he didn't get it, then his word is no good. He has reasons to lie and reasons to tell the truth. I cannot think of one good reason why he should lie other than for profit. If someone paid him a bribe, he might do it. If he's telling the truth, then my above statements hold true. Pick one: either (1) he's in on it, (2) he's incompetent, or (3) it's safe. If someone switched it out, it doesn't nullify the above statements either. It just takes his decision out of his hands. He's still either (1) In on it, (2) Incompetent, or (3) It's safe. There is however a possible fourth alternative which would have to be taken into account, a huge conspiracy if true: (4) There is an actual conspiracy. The vaccine is not safe, but he was given a placebo without his knowledge to keep him from suffering its effects. Occam's Razor suggests that this is nonsense. If there is actually a cabal behind it, they'd want him dead and out of the way. What better way to get rid of your political enemy? What better way to hide it? ("He died of long covid.") What better way to convince more people to get the vaccine and give more political power to his opponents?
