The vax changes DNA, God created DNA. Back before the flood fallen angels had sex with women, creating giants (See Gen. Ch. 6). The souls of the giants are not allowed entry into heaven, they are the disembodied demons that attack humanity. Before the flood those giants committed murder, sodomy, cannibalism, and no doubt, pedophilia. Everything those giants did in the earth they push humans to do because when they possess a human they derive pleasure from what the human is doing. The demons crave sodomy, murder, etc. A really well researched book is "Genesis 6 Giants" by Stephen Quayle.
Main point here, the devil is pissed that the giants they created are not allowed an exit from the earth. The devil is a counterfeiter who hates hates hates humanity. His evil plan may be to change human DNA enough so God will not admit the human souls into heaven, to be earthbound. The devil is stupid- God has a plan to defeat this evil. And it's coming soon.
