My employer requires a negative test to return to work, but not a vaccine, luckily. I’m happy to take the test because I’m the only one in the office who’s not vaccinated, and no matter which result I get, I win.
If it turns out negative (which I’m sure it will, since my taking extra vitamins and zinc), then all the vaccine freaks at the office will be mad at my dirty anti-vax self for not getting covid. Win for me, I’m living in their heads rent free. If it turns out positive, I still win, because I’ll survive it, proving the vaccine is unnecessary and now I’ll have the antibodies, which are stronger and better than the vax.
Win win, losers.
UPDATE: Got a negative result. In the office as we speak.
I'm sorry about your friend. For a possible theory, read the Spartacus letter which states that the virus is only around for a handful of days, which are the only days that antibody/ivermectin/HCQ is actually helpful. After the virus has been defeated, you're battling the inflammation in lungs (and elsewhere), and administering antibodies after that point is not going to be helpful, since no longer a virus present in the host.
