From CNN, there were two health care workers, who carried an adrenaline auto-injector who had anaphylactoid reactions. The vaccine is supposed to stimulate the immune system, people with serious allergies have overly vigilant immune systems. This isn't a surprise reaction, but it would be good if they could reduce the possibility of a reaction.

It was close enough to "fear-mongering" for me to think of it as such. the "we have *no clue* what injecting..." is bullshit. They have a clue that it will provoke an immune response. I think most of us are fairly inured to most irrational fear of the unknown (to them, at least).

As for "People who are not frontline workers, like me, can afford to wait, though.", we don't have a choice in the US. I'll get the vaccine whenever I can, but I figure I'm not at the top of the list.

Those of us who aren't afraid will hopefully be enough to protect those who won't, or don't, get the shot from being infected, but it's pretty far off.
