Just to address confusion - 12 of 42 deaths among those doubly vaccinated *does not* indicate vaccines aren't effective. If they weren't effective, we'd expect almost all deaths to be among fully vaccinateds, given vulnerable groups have very high levels of complete vaccination. https://t.co/cTGnyKhUnX
