No. I believe the world to be very corrupt but there's a logic to it. For instance, it's estimated that the superrich have buried away something in the order of 50 trillion dollars in offshore bank accounts over the past decade or two. That's not a made up figure, either.
Meanwhile, the sales per annum of all the major vaccine producers combined total less than 100 billion dollars. That's not even equivalent to the worth of one of the corporations that manufacture these vaccines (Pfizer made a profit of 20bn prior to the vaccine)

The world is corrupt and a couple hundred billion isn't a small sum over a projected period of five years, but it's a very small sum in terms of actual offshore levels of corruption. Also, some of these vaccines are being dispersed on an IP-free basis. That means there is little to no profit to be made, or a nominal amount in any case.
Not trusting a system you cannot personally audit isn't illogical but that's the nature of modern society. All systems of mass production run on an assembly line logic which disaggregates personal autonomy in favour of split and fractured fordist systems of production. There is no artisan vaccine maker.
Oh yeah, and the actual cost to the global economy, of worldwide lock-down, has been of orders far greater than the profit made from any vaccine or collection thereof. The best you could argue is that Covid offered a convenient or inconvenient moment within which to restructure global systems of production. That is true, at least. It's also an open conspiracy as everyone knows about it. Your problem is between correlation and causation.
