The drug is itself what becomes toxic not the delivery methods. Read the last paragraphs again carefully.
Except now, endless dosings of that very same tech are being mandated. Note: no announcements at any point about how they found some fix for this problem.
I've updated my original post with a second story from the same site that makes this problem clearer (spells it out in different words):
"But that hasn’t worked out so far. Moderna’s attempts to make actual drugs from mRNA have been repeatedly hamstrung, proving either too weak or too dangerous to test in clinical trials, former employees and partners said. The company has instead prioritized vaccines, which can be dosed just once and thus avoid the safety problems that have plagued more ambitious projects."
The articles are quite clear that they didn't want to make this decision but felt forced into it, because many years of investor funding had failed to bring a single drug to market. Vaccines were the Hail Mary move to save the company from extinction, even if it made investors unhappy. Then COVID came along and suddenly, vaccines were big business and nobody worried about toxicity anymore.
It amazes me anyone is still willing to use the E word on anything COVID related. It's just embarrassing at this point. The "experts" assured us just months ago the vaccines were 95%+ effective. The fact that effectiveness declined so fast surprised them and now they're trying to rewrite history to claim it was known all along.
There appear to be no experts in COVIDS, viruses or vaccines. They're all in denial that their self-proclaimed experts beliefs have been invalidated dozens of times over since the start of this.
