Brace yourselves because this is a shocking story. It begins with a study published in Nature—a top scientific journal trusted by experts.

Researchers in Poland were studying how Moderna's COVID-19 vaccine works inside immune cells (Krawczyk, 2025). They used advanced technology to track the vaccine's mRNA after injection.

But when genomics expert Kevin McKernan analyzed the raw data, he found something shocking—something the original study missed.

Among millions of RNA sequences from vaccinated mice, he discovered not just the expected COVID spike protein code, but also pieces of the so-called gp145—a gene from Moderna's experimental HIV vaccine.

These were mixed-up RNA sequences—part COVID, part HIV—fused together in a way that shouldn't happen.

This wasn't part of the approved vaccine formula. It wasn't reported to regulators. And nobody getting the shot knew about it.

McKernan is stunned:

"How did HIV vaccine material end up in a COVID shot? Why is gp145 attached to the spike protein?"

So now we have excessive amounts of plasmid DNA and undisclosed genetic sequences in these mRNA 'vaccines'—specifically, simian virus 40 (SV40) elements in Pfizer-BioNTech's vaccine, AND HIV-related sequences in Moderna's. The producers must have known all of this and yet did not declare it when bringing it on the market.

"How on earth did this get into this SARS-CoV-2 vaccine, and what is gp145 doing covalently linked to spike?" asks McKernan. You can read his excellent article on this here: Why is a Fauci HIV vax sequence in a Moderna's C19 vaccine?

Here's a closer look at what we know so far in terms of DNA contamination of these mRNA shots…

1. SV40 Promoter/Enhancer Sequences in Pfizer-BioNTech's Vaccine

Independent genomic analyses, including work by Kevin McKernan and Dr. Peter McCullough, identified DNA contamination in Pfizer-BioNTech's mRNA vaccine, including sequences linked to SV40 promoters/enhancers (McKernan et al., 2023). These sequences are not part of the vaccine's active ingredient but appear to stem from the plasmid DNA used in manufacturing.
