Well done on the anti-singularisation front. A sound argument against all the eggs are always in one basket.
And in recent reading doctors in the early 20th century early saw cancer. The rates of cancer began to rise with vaccines and the rates have roughly increased with the increased rates a d numbers of injections. Does correlation equate to causation? Not exactly! It does seem to relate to correlation, though. And isn't that sufficient to create curiosity and even the thought of pausing them, especially ones that are for nearly non-existent bad outcomes?
All the best with what is changing. Everything changes!
