RebE > Use j&j which does not use this technology
I think he already found a tiruts for that also. But let’s put aside the medical discussion – it is understandable that someone can get lost in medical terminology about a cutting-edge technology. Go, down to basics. So, someone is not vaccinating, and thus, are a higher danger to the society around him. If he is Jewish, then to the Jewish society.
Then, there are kosher solutions:
– limit your interaction, especially with vulnerable people,
– do not congregate in large groups
– wear a mask
– do weekly COVID test (this is now offered as an alternative to some government workers)
It may be unclear where exactly to draw the line, but a person should do some hishtadlus in bein adam l’havero in this case. I hope that vaccine sceptics can report on what they and their haverim do in this regard. If they are not, then we need to talk about middos in a wider context, not just about medical and statistical education.
