From the CDC:

"People who have gotten sick with COVID-19 may still benefit from getting vaccinated. Due to the severe health risks associated with COVID-19 and the fact that re-infection with COVID-19 is possible, people may be advised to get a COVID-19 vaccine even if they have been sick with COVID-19 before."

>Some early evidence suggests natural immunity may not last very long.

Doesn't the evidence so far suggest the exact opposite?

I think so. The antibodies drop off rapidly but that's normal with viruses. Sars 1 patients still have T cell response 17 years later.

This doesn't explain why it will benefit someone. The text is alarmingly vague.

> Due to the severe health risks associated with COVID-19 and the fact that re-infection with COVID-19 is possible (...)

Presumably one could get re-infected after vaccination, too, isn't that how vaccines work? I.e. they try to simulate as close as possible a real prior infection.
