Niangon gives a skin reaction and is bad for the lungs, Yew is completely poisonous except for the red of the berry (but I wouldn't eat it) Wenge splinters give rashes and they become sore. In fact most woods are not very good for the lungs. Fruit woods tend to be the safest, the others have all of their various toxicities so the wood database is the main reference.
The reason for not wearing gloves on a lathe is that if they get caught, the subsequent finger ripping is too fast for you to get away from!! Just as not wearing safety glasses tends to attract fast moving lumps of half turned wood... trust me on the latter and I now wear ordinary glasses with hardened lenses because I need varifocal glasses but they don't work properly behind safety glasses (which also interfere with my hearing aids) so I pay extra.
Vaccinations are personal, after 25 years in the military (vaccinated all over for every potential problem) the only vaccination that ever caused me a problem was tetanus which gave a very sore arm the rest have never troubled me and I've had 7 covid jabs!!
