I think people are letting their emotions get in the way of thinking logically about his reporting. The idea that these pharmaceutical products were under tested and overstate efficacy and understate side effects is not a particularly hard to believe claim https://twitter.com/TheEliKlein/status/1361659190704537605
We already know that the shot makes many people too ill to work, and yet the authorities tell us that side effects are rare and should only include a mild fever. I think he is catching flak because he is over the target.
I see nothing in the national level Israeli data that shows a dramatic effect of vaccines and it may very well be possible that the people most at risk (the elderly and infirm) are not well protected while the people at least risk are.
This is to say nothing of more exotic negative externalities of the vaccines, like antibody dependent enhancement, which was a problem with the early SARS vaccines and doesn't seem to have been discussed much for this crop.
Bottom line is I think the position of @AlexBerenson of informed skepticism should be the DEFAULT. We are dealing with a totally novel technology with yet unproven benefits outside of a single and extremely manicured corporate clinical trial.
I could write an entire other thread about the psychology going on here, about a population with a gun to its head begging for anything at all to release them from their year long nightmare. For now, I think a wait and see approach is best.
