Uh, it doesn't. It's mRNA in a lipid that couldn't pass through your skull first, in case you forgot about that, and then your blood/brain barrier, which can only be crossed by the most tenacious microplastics?

In fact, it can't even reach the nucleus of normal cells if it wanted to. It can only teach your cells to make a crown shaped cell and then begone.

It's amazing what a little mystery juice can do when you take the goggles of wilful stupidity off your face.
