Cue the usual suspects who ignore the obvious and say “safe and effective”.
You are right in quoting others: “The covid vaccine is safe and effective.”
The polio vaccine lasts a lifetime. The tetanus vaccine lasts ten years. The covid vaccine does not fully protect you for six months. It is not effective. So let’s correct this to:
The covid vaccine is safe and ineffective.
The nRNA shots are not traditional vaccines. Let’s just ignore the changing definitions of “vaccine” and realize that the mechanisms aver very different. So, let’s correct again:
The covid shot is safe and ineffective.
Safe? How would anyone have known for such an experimental treatment? However, by now those in the know, know. So let’s make our final correction:
The covid shot is unsafe for the young and ineffective for all.
