The thing to know about vaccines is that most are for profit and some (very few) are not. Jonas Salk, the creator of the Polio vaccine, did save thousands of lives. The original Polio vaccine's ingredients? Mainly just the dead Polio virus in a culture medium. And Salk's big contribution was not just this medicine, it was the stance he took against its privatization, against Big Pharma. When they came to ask him if they could buy the vaccine's patent from him, he clearly said no. Salk officially declared that this vaccine formula would be made a public resource and kept that way, always.
This decision of his is known as one of the historic founding moments of the Open Source Movement. Big Pharma, the main creators of today's "vaccines," are still working for profit. It is still big business to them. And their vaccines contain a proprietary mix of known toxins and heavy metals, along with live strands of viruses which people, often children, then contract. They don't make full disclosure of ingredients because that would open their process up to actual scientific inquiry and hit their profit margin. It might even show them guilty of mass crimes against humanity. Instead they rely on you feeling like they are an irreproachable authority that has the medicine you need whether others blindly agree or not. They need you to believe that you could never understand their analyses, that you could never have a valid opinion about them. Your induced ignorance on the matter is the safeguard mechanism for their profit.
Do you see how this goes now?
The scientific method requires independent verification of findings, and so is open source in its nature. Anything else is business research. You can't verify findings that remain privatized. I rarely mention my degree in physics, but want to do that here. I want you to know, I am a scientist, and not one working for the love of money. I advocate for open information like all other actual scientists. Like Tim Berners-Lee, who created the World Wide Web to share data with other scientists at CERN. Like Tesla who worked to create free energy for all. They understand science. Big Pharma does not.
