Skin tests

I was innoculated with 3 tests - TB and I don't know the other 2 to see how I react. I don't expect a reaction but it is something that is done for this protocol.

From the reading I have done on vaccine trials, skin tests are always done in the first place so that they can see how your body's immune response is working.

Yes, that's what I've read also. Sometimes tetanus is given also to measure immune reaction.
