The time has finally come to invest in RNA malware detection.

In all seriousness though, would it be easy to check these vaccines for authenticity via some simple PCR test?

You could do reverse transcription and sequencing to confirm the presence of the full length spike protein. That should tell you with pretty high confidence that it’s authentic. But the really interesting “biopunk novel plot” future would be some sophisticated counterfeiter who is actually producing the correct mRNA sequence and packaging it in LNPs. If the counterfeiter was able to charge a thousand dollars per dose, it could be quite profitable even at small scale.

This is not a product I would trust off the dark web.

Also being in the UK makes the cost of this appear ridiculous. How do these prices compare to anywhere that is actually charging for the vaccine?
