Given the desperate times, it actually seems like an ideal time. Even if there is some unknown side-effect, it only has to be less worse than the current situation to still be a net benefit.
What if it's more worse? I don't think desperate times call for throwing caution to the wind. A fundamental principle of medicine is "First, do no harm."
You say that now, but when you're part of a vast planet-wide meat computer transformed by the "vaccine" that aliens developed to turn us into their next-gen CPUs (5*10^11 neurons per sq. Kilometer!) ... Well, I'm guessing if that happened you'd feel a bit silly.
