It looks to me like she had a vagal reaction.

I see it frequently in people getting any kind of shot or even in people watching someone else get a shot.

Their blood pressure drops, pulse drops, and they faint.

Usually fine just by laying them down and elevating their legs.

The idea that the vaccine is some super poison that caused her to faint immediately is silly. She had a vagal reaction. It irritates me when we promote material that we like even if it is wrong or misleading. I know the other side does and so we think we have to do it as well.
