Stanford Scientists Reverse Engineer Moderna Vaccine, Post Code On Github (vice.com) 111

An anonymous reader quotes a report from Motherboard: Stanford scientists saved drops of the COVID-19 vaccine destined for the garbage can, reverse engineered them, and have posted the mRNA sequence that powers the vaccine on GitHub for all to see. The GitHub post is four pages long. The first two are an explanation by the team of scientists about the work, the second two pages are the entire mRNA sequence for the Moderna COVID-19 vaccine. "RNA vaccines have become a key tool in moving forward through the challenges raised both in the current pandemic and in numerous other public health and medical challenges," the scientists said on GitHub. "Despite their ubiquity, sequences are not always available for such RNA. Standard methods facilitate such sequencing."

According to Stanford scientists Andrew Fire and Massa Shoura, this isn't technically "reverse-engineering" a vaccine. "We didn't reverse engineer the vaccine. We posted the putative sequence of two synthetic RNA molecules that have become sufficiently prevalent in the general environment of medicine and human biology in 2021," they told Motherboard in an email. "As the vaccine has been rolling out, these sequences have begun to show up in many different investigational and diagnostic studies. Knowing these sequences and having the ability to differentiate them from other RNAs in analyzing future biomedical data sets is of great utility." [...] According to Shoura and Fire, the FDA cleared the Stanford project's decision to share the sequence with the community. "We did contact Moderna a couple of weeks ago to indicate that we were hoping to include the sequence in a publication and asking if there was anything that we should reference with respect to this... no response or objection from them, so we assume that everyone is busy doing important work."

      There's nothing to figure out this vaccine is easy to make at home. Ideally, though not required, you need a DNA printer (you can get a cheap oligo synthesizer on eBay anywhere from $10,000 to $50,000 if you want the high end shit). If not, you can still make it for around $500. Of that $500, $300 is to order a strand of DNA with the vaccine code on it because you were too cheap to buy an oligo synthesizer. Then, you need something called a DNA dependent RNA polymerase, probably T7 polymerase works best. You can get it many places cheap, although you probably should have your credentials as a biohacker revoked if you don't have some lying around. You just mix the DNA strand and the T7 polymerase together .. and within an hour you have the mRNA for the vaccine. Then you encapsulate it by (essentially) mixing it in some lipids (which you can buy it cheap, my favorite supplier is Avanti Polar Lipids) and if you wanna be fancy you can add some PEG (poly-ethylene glycol). PEG costs so little that you have to buy a massive quantity at a time, what a ripoff. Oh yeah you might want to purify it some with an HPLC, though it might not kill you even without purification.

      I simplified the steps a little bit, but it really is that easy. Of course, if you try to do it based on just the above and lacking experience you might die or worse.

      My point is that this vaccine is easy to make, it's only a matter of doing it and not going to jail for giving it to somebody because you said F U to the FDA.

    • The lipid pfizer uses is available commercially to anyone. Moderna's lipid formula and structure is known so it can be synthesized .. granted that it may take some trial and error. Also, that article is a bit of exaggeration, there are enough published works on lipids that are good enough.

      There is zero trade secret whatsoever. It is just an mRNA expression backbone with the spike protein sequence. Good mRNA expression vectors are well known. The spike protein sequence is well known. They used a stabilized version published by University of Texas at Austin.

    • Trade secret law would only apply if the Stanford scientists received the secret under NDA and then published anyway. Stanford has an open research policy and so would never have signed such an NDA. Since Moderna is publishing their vaccine in liquid form, declaring this a trade secret would not be very effective legal protection of their IP. Instead they have patented as much as they legally can: https://www.modernatx.com/pate... [modernatx.com]
    • Trade secrets are difficult for others to properly acquire or independently duplicate, subject to reasonable measures to guard the secrecy of the information, and not known outside of the particular business entity[source] [nolo.com].

    For anyone who is interested, I aligned the Pfizer and Moderna sequences as provided in the pdf. The encoded spike proteins are identical, but the mRNAs are different.

    Thanks to redundancy in the genetic code [wikipedia.org], multiple RNA triplets can often encode the same amino acid. The random nature of codon optimization algorithms would lead to the two teams choosing "different' mRNAs that still reflect the codon usage stats of a human mRNA.

    There are also notable differences in the 5' (upstream) and 3' (downstream) untranslated regions, or UTRs, that regulate the stability and translation of mRNA molecules. It would be interesting to test them side by side in the lab and see if there is a significant difference in protein production.

    A final difference between the two vaccines that is not encoded by the mRNA is in the composition of the lipid nanoparticle that is responsible for delivering the mRNA to the host cells for protein production. Probably the two vaccines use similar but different mixtures of positive charge and lipid. Nanoparticle technology allows mRNA, an enormous highly negatively charged molecule, to be internalized into cellular endosomes and escape to the cytoplasm where it can guide the production of antigenic protein. Without the special mix of positively charged fats (cationic lipids), the mRNA would be dead on injection thanks to serum RNases, and it would never accumulate significantly in the cell.

    Another interesting note is that the researchers have posted the sequence of the DNA copy deduced by reverse-transcribing the mRNA, since mRNA doesn't contain "T" bases but instead contains "U" bases. On top of that, therapeutic mRNAs (including Pfizer and Moderna molecules) don't even use U, but instead incorporate 1-methyl pseudouridine (m1-Psi) [caretdashcaret.com], which avoids activating the innate immune system of cells.

    Don't confuse the innate immune system with the adaptive immune system. The job of the innate immune system is to recognize incoming viruses, often in the form of extracellular RNA, and initiate the shutdown of protein synthesis and often cell death. Earlier generation mRNA vaccines that incorporated U instead of m1-Psi exhibited strong activation of the innate immune system and were less effective at hijacking cellular protein producing machinery to manufacture antigen proteins.

    All in all it's amazing what has been accomplished in the last year, but it was only possible because of decades of underlying research into this new therapeutic technology. Truly a triumph of chemistry and biology.
    • Very informative post! A little dense on technical jargon though. I had to read a bit of the Uracil wikipedia article to understand [wikipedia.org] what you were talking about with regards to T-base and U-base.

      So DNA contains ATDC (adenine (A), thymine(T), cytosine (C), and guanine (G)). However, RNA uses uracil instead of thymine, if I understand correctly. But the innate immune system would respond if the vaccine contained uracil (and reject the mRNA before the spike protein was produced), so they used some other c
      • You got it!

        Jargon is unavoidable I'm afraid, but the basic idea is that adding a single methyl group (a carbon with 3 hydrogens) in the case of m1-Psi can block the cell's native recognition machinery, but not interfere with the protein translation machinery. A very clever and elegant biohack!

  • "We did contact Moderna a couple of weeks ago to indicate that we were hoping to include the sequence in a publication and asking if there was anything that we should reference with respect to this... no response or objection from them, so we assume that everyone is busy doing important work."

    "important work" - like having their legal team working on a lawsuit!
