My friend's mom technically died in a clinical sense 5 minutes post first jab while still in the parking lot under observation. My other friend's brother dropped dead exactly 36 hours post 2nd jab. Both were zapped back to life. One of them had a pre-existing heart condition.
I know at least one ER RN that readily admits they're seeing a high increase in ER cases of young (20s) people with various neurological and cardiac issues 1-14 days post vaccine (and are almost never treating them as vaccine-caused issues hence they stay unreported). The apologists will say things like "but you don't know it was the vaccine". Sure, you're never 100% positive about anything dealing with as complex system as a human body. What you should do is start with "what has changed recently", and almost always the patients that my RN wife handles say "I've been recently vaccinated.".
