You're right, but it's getting downvoted because it has the same basic shape as the "people aren't creating antibodies and can get reinfected" doomer meme which is making the rounds. Also, FWIW, if getting the actual disease doesn't generate sufficient antibodies to confer immunity, being dosed with a vaccine wouldn't either. Whether vaccine-supported or not, herd immunity is the most likely outcome (unless the disease becomes endemic instead). What remains to be seen is how many people have to get ill to get there.
