Ya those definitely gotshook up.
Anyways a rn I know was offered overtime to give vax at toledo ohio hospital ,last may or June whenever the push had started. After a few weeks she refused to go back.
She said she felt like she was killing people.
Oh and get this there was a handler their asking people their occupation and if they were laid off or essential worker. The lady would send important people to the clear shot and unemployed would get the tannish tinge vax.
2ell the tan one always had people passing out or getting
Sick.
We at war people they just didn't tell us

I was just reading how to prepare vaccines. For every vaccine before, they tell you to shake the vial, and the syringe.

For the Pfizer and Moderna, "Do not shake" and then they say if you do shake you should contact the manufacturer.

So I am wondering why? I can't find an answer online. So in addition to having to keep them cold until right before use, you can't shake them. Strange.

Dumb ass, its fragile like insulin. Peptides are a class of drug very fragile.

So there are different vaccines?
