As an ancillary note for “now” - make sure your tetanus vaccination is current.
I’ve heard dying of tetanus is particularly unpleasant.
Tetanus is one, TB is another. Yes, we don't have to worry about TB now but it wasn't that long ago when it was a real problem. In a survival situation it is likely to become a problem again. Hep A&B are also a good idea. Not a problem now but in a survival situation it could be good to know you won't catch those diseases from the blood that sprayed on your face
