> Not vaccinating though is an inaction

Not clear at all to me that failure to vaccinate is inaction rather than action. Viruses push our understanding of moral culpability and causality, but the comparison to blood donation isn't apt. In the case of donation, we're talking about an abstract stranger, in the case of the virus, perhaps we're discussing a distant downstream effect, but we could also be talking about killing your neighbor or grandma.
