A Moderna patent filed in 2016 contains a 'reverse complement' of a 19-nucleotide sequence found in the SARS-CoV-2 genome.

Notes on verification

Multiple independent fact-checking and science-review sources (Science Feedback, PolitiFact, China Daily citing peer-reviewed rebuttal) confirm the literal technical finding: a short 19-nucleotide sequence match exists between a 2016 Moderna patent and the SARS-CoV-2 genome. However, these same sources emphasize this is a statistically unremarkable coincidence (the sequence is short and found in many other organisms/genomes) and does not support claims that Moderna engineered the virus.
