Yes... as well as NAC. My understanding is that NAC helps remove foreign agents. So, if there is a bioweapon (which, I tend to think there is, but it was not necessarily a self-propagating weapon, but rather a form of poison to scare people into taking the real weapon--the vax--and, no, I do not have sauce, just my own reasoning), then it is good to get help on board in the form of NAC to assist in removing foreign radicals.
