“Let’s start with a thought experiment: If an engineering design flaw exists and no one measures it, can it really injure people or kill them?” a Twitter user named Ehden writes.1 He goes on to discuss an overlooked aspect of the COVID mRNA shots, something called “codon optimization,” which virtually guarantees unexpected results. Ehden explains:2 “Trying to tell your body to generate proteins is hard for many reasons. One of them is the fact that when you try to run the protein information via ribosomes which process that code and generate the protein, it can be very slow or can get stuck during the process. Luckily, scientists found a way to overcome this problem, by doing code substitution: instead of using the original genetic code to generate the protein, they changed the letters in the code so the code would be
