Why should anyone agree with your assertion that, "the justification for not doing so, (ie. not allowing one group to be vaccinated so that they might meet testing requirements), is that it would be unethical to deliberately withold (sic) vaccinations from people."
I was thinking on the other side of this, of course. To remain scientifically objective on this; if vaccines possibly could be much less benign than advertized; shouldn't those willing to allow foreign substances of unknown origins and purity, to be unnaturally introduced into their bodies; be notified of all the warnings listed in their legally-required vaccine inserts, beforehand?
Mercury compromised or not; there are some sobering words printed there that ought not be ignored when following this unnatural assault on our natural immune systems.
