Not if the evidence used for the bans was admittedly not based on actual evidence of harm in humans in its use as a food additive but in acute toxicity tests in animals. How do vaccines perform in accute overdose safety in mice, I wonder?
In any case OP's question about evidence for the claims in the article is still reasonable IMO.
COVID vaccines have a specific use that nothing else provides. When there was the slightest bit of concern about the J&J vaccines (which turned out to be unfounded), the FDA did ban its usage.
The food additives in questions are not saving anyone’s lives even in the best case scenario. They’re only making bread last longer by a day or so.
There is non-zero risk for any and all the vaccines and they don't ban them. It's a measured and scientific approach that is taken. And cost and availability of food is absolutely of critical importance for peoples' lives.
In any case OP's question about evidence for the claims in the article is still reasonable IMO.
