I'm an industrial engineer at Moderna and the other one of us is a process development engineer. I'm sure the same thing is happening with Pfizer-BioNTech. It was hard to put things together based on the small quantities of additions happening in manual step (highly unorthodox for a continuous process production). The explanation we got was highly sensitive trade secret adjuvants being added. Digging in deeper showed how sensitive it actually was.

Most people's understanding of this novel vaccine type is that it works as follows:
1. Make mRNA coding for S protein
2. Make lipid nanoparticle delivery system
3. Profit

How it actually works from what we've uncovered:
1. Make mRNA coding for S protein
2. Make mRNA coding for mutant versions of CYP19A1 and CDKN1B in smaller amounts
3. Make sure that while delivery system for (1) mostly ends up in liver, most of (2) ends up in the gonads
4. Make sure form and quantity of additive upregulating LINE-1 reverse transcription activity makes it hard to detect among legit adjuvants
5. Effects from (2) integrated by (4) are recessive; mildly oncogenic effects in vaccine recipients unlikely to be noticed for many years
6. (5) recessive but since most of population vaccinated, in next generation female offspring have premature ovarian failure

(6) coincides with poor people being obsoleted by AI and robotics, so we didn't have to dig for motivation.
We've taken precautions but fear for our safety. So far I don't think we've raised suspicion, but can't be sure. Not sure what to do. Avoiding taking the vaccine makes us prime suspects for this leak.
