The odds of the vaccine killing you are tiny - much less than COVID-19 killing you. And there are at least 2 deaths from reinfections that were part of a University of Missouri study (out of 63 reinfections), so your worst case should you get reinfected would also be death. If you're going to argue that dying from the vaccine is your worst case scenario then you have to be consistent and acknowledge that it's also your worst case scenario should you be reinfected. Is there a chance you still have immunity from your infection? Yes. Is there a chance you don't? Also yes.
Reinfection may be rare, but so is death by vaccination. If you've never had an adverse reaction to a vaccine before then the odds are overhwelmingly in favor of you not having an adverse reaction to this one.
A review of more than 9,000 US patients with severe COVID-19 infection showed less than 1 percent contracted the illness again, with an average reinfection time of 3.5 months after an initial positive test.
