My take on it is that vaccines are very far from nature and also that damage is done not only by the chemicals in them but also by the physical part of sticking a needle into the body.
I also think that scientific studies and what we call Science today is like a tiny grain of sand compared to what our ancestors who built the pyramids knew about life and health and science. Apparently, they even figured out the distance from the sun to earth and had highly advanced knowledge of astronomy and astrology and the four elements and the movement of the sun and the seasons and much more. And they understood the effects of different vibrations on people when the celestial bodies were in different positions.
Either way, every single one of us is limited by our point of view, in how we see things. To express different opinions respectfully can help people learn and perhaps think of new things.
