They're all shit, no matter if new or old. They're all their way of making some kind of intervention into the human body. Who knows how long the experimentation went on before they came out with this one. And all the facebook karen antivax shit is a psyop same as flat earth. Find a bunch of useful idiots who embarrass themselves with flawed logic and give them social media coverage. Remember that the vaccine is based on their science model that they teach.
