did the pfizer vaccine even really have a drug trial?

if the process is the product (and it is) then pfizer's product looks like it went to market untested
the discovery by brave fellow feline kevin mckernan (who actually did what should have been done right from the start and went out and gene sequenced the pfizer covid vaccines) that the vaccines were wildly impure, low integrity, and contained not only copious amounts of contaminants, but actual active compounds like plasmids that were, quite literally, spike protein factories was extraordinary.
the jab was literally full of the compounds used in its fabrication that had no place in a final product and these are not even just toxins, they are plasmids, actual factories for making pathogens. the idea of a “safe level” for such a thing seems fraught and they missed the alleged limits by an order of magnitude anyhow. from FEB substack
