Best theory I've heard yet is mrna goes into the body, is synthesized into a protein, then has the ability to alter dna strings to re-write it to (unknown currently) whatever the mrna is coded to re-write to. Reports coming out that essentially vaxx'd peoples bodies are turned in a manufacturing plant for altered mrna proteins(?) that are somehow "shedded/transmitted" out by unknown means to unvaxx'd people. This is why people say avoid vaxx'd people. Dr. Sherry Tenpenny is excellent to listen to. It is worth noting even her and the other blacklisted Drs say even they don't fully understand what it's doing. Check ScottMckay.us or his Rumble account Patriotstreetfighter for more info. Will try to get the link to a Dr. Tenpenny interview with Scott McKay.

Edit: https://rumble.com/vg3ik5-4.23.21-interview-with-dr-sherry-tenpenny-and-dr.-p-following-our-same-day-.html Scott McKay put this on his channel after his interview with Dr. T. This is a shocking listen if you've never heard it. Also dont forget tge article that popped up that a 5month old baby died 2 days after it's mom got vaxx'd and breastfed. Kid appeared to have no other complications that would've killed it.
