Don't worry if you experience allergic shock we have epinephrine on standby. It might not work and its use is associated with Alzheimer's onset but don't worry! Safe and effective!
The waiting period of 15 minutes after a vaccine has always been recommended. It's standard medical recommendation and safety.
I see the CDC website says that a 15 minute wait after getting a tetanus shot is recommended due to a fainting risk. But I bet this is not widely observed. I surmise they had already judged me to not be a fainting risk, since I didn't faint when they were sewing me.
According to the CDC the rate of anaphylaxis is incredibly low with the COVID shot[2].
