Error in "History"?

The first paragraph in history says "The idea that mRNA could be used for therapeutic purposes was first realized in 1989 by researchers at Vical, a Californian biotechnology start-up.[3][15] Researchers working with the Salk Institute that year published an article showing that nanoparticles could transfect mRNA into cells." and for both these claims, it refers to citation 15. The issue here is, the paper at 15 exclusively belong to the Salk Institute, and from what I can tell at the very least Inder Verma and Robert Malone were both under the employ of Salk, not Vical, at this point in time (Felgners association I can't find). It were the mice studies that were carried out a year after this paper was published that was part of Vical.

Tracking Citation 3 points out the culprit; this paper misidentified the institute as well despite also citing it, so its a faulty citation chain at play here. I recommend clarifying that it was realized by the Salk Institute.

I don't know whether this was corrected in the past but ended up getting deleted when Robert Malone was needlessly highlighted for his accomplishments within the team, but I world recommend correcting it as following the citations seems to declare it as self-evidently wrong

According to his faculty profile, Felgner worked at Vical. 2601:249:8180:28D0:686E:C59D:A30F:2945 (talk) 23:00, 4 July 2021 (UTC)

Not sure if this is the right section to bring it up in, but am I missing something or is the does the first sentence of "History" misstate what happened? "The first successful transfection of mRNA packaged within a liposomal nanoparticle into a cell was published in 1989." Dimitriadis did this in 1978. https://www.nature.com/articles/274923a0 The Malone, et al contribution was drastically increasing the efficiency by using a newly developed liposome, not being the first successful transfection or mRNA in a liposomal particle.

Sloppy use of references concerning mRNA research and side effects

One paragraph in this article uses suggestive argumentation with outdated or inadequate references:

"Up until 2020, these mRNA biotech companies had poor results testing mRNA drugs for cardiovascular, metabolic and renal diseases; selected targets for cancer; and rare diseases like Crigler–Najjar syndrome, with most finding that the side effects of the mRNA delivery methods were too serious.[29][30]"

Reference [29] is dated 10 January 2017 Reference [30] is dated 13 september 2016

These references can't be used for a statement that the side effects of the mRNA delivery were too serious 'up until 2020'.

"mRNA vaccines for human use have been developed and tested for the diseases rabies, Zika, cytomegalovirus, and influenza, although these mRNA vaccines have not been licensed.[31]"

Reference [31] links to a webpage of the Centers for Deisease Control and Prevention about 'Understanding mRNA COVID-19 Vaccines'. There is nothing on this page about mRNA vaccines not having been licensed.

"Many large pharmaceutical companies abandoned the technology,[29] while some biotechs re-focused on the less profitable area of vaccines, where the doses would be at lower levels and side effects reduced.[29][32]"

Reference [32] is a CNN article that opens with a description of a meeting of vaccine developers with President Trump. The first line of the article reads: 'It almost felt like an episode of "Shark Tank".' This statement inspires little confidence that the author is an unbiased source. And there is nothing in the referenced article that substantiates anything in the sentence or paragraph. Reference [29] is the same reference as in the first line of this paragraph, linking to an article from 10 January 2017.

There is still the issue of the citations 33 and 34 not supporting the statement. The article states, "mRNA drugs for cardiovascular, metabolic and renal diseases, and selected targets for cancer were initially linked to serious side effects," but the articles only note the difficultly in getting mRNA into cells without "nasty side effects." Neither article mentions serious side effects associated with any specific drugs (or categories of drugs). Torven (talk) 16:07, 16 September 2021 (UTC)

Side Effects: Blood Clots

In the United States "CDC and FDA identified 44 confirmed reports of people who got the J&J/Janssen COVID-19 Vaccine and later developed TTS. Women younger than 50 years old especially should be aware of the rare but increased risk of this adverse event.

"Denmark has ceased giving the Oxford-AstraZeneca Covid vaccine amid concerns about rare cases of blood clots, the first European country to do so fully." "Camilla, one of three Danes to be diagnosed with the side-effect VITT, experienced telltale symptoms of extreme headaches, bruising and clotting that could have proved fatal. Of the three Danes to have suffered from VITT – a rare and often fatal side-effect of the AstraZeneca vaccine – Camilla is the only survivor."

Add to #Mechanism, the mRNA ligand function which also modulates the immune system, rather than only through its genetic code

RNA vaccine#Mechanism

mRNA influences the immune system not only by its genetic code but also by the shape of its molecule. It functions as a ligand. As such it can bind to Toll-Like Receptors (TLR).

The immunomodulatory effects of the ligand function of mRNA depend on whether the nucleosides are methylated. Pseudouridine Ψ (methylated uridine) uniquely suppresses the capacity of RNA to activate primary dendritic cells through binding to TLRs and the suppression is dose dependent.
