If you get the vaccine there is a 1 in 50,000 chance that you will not get immunity and only have reduced effects. At that point (if you are that 1 in 50,000) you have a 96% chance of having reduced symptoms and a 4% chance of having severe symptoms (these are guesses made by the scientists). From those with severe effects (if you are in the 4% of the 1 in 50,000 you have a 1% chance of dying). Purely statistically speaking that means a small congregation of JWs may still die from COVID if the entire population of the world was vaccinated.
All other billions will have full immunity (meaning you can’t get sick, can’t spread it etc).
Do note that your chance of dying from the flu after a flu vaccine is orders of magnitude higher.
Here are your chances of dying for various other reasons: https://injuryfacts.nsc.org/all-injuries/preventable-death-overview/odds-of-dying/
Since the vaccines were rolled out, nobody with the US funded vaccines has died from COVID.
