Ive suspected all along the massive media push that "natural infection only generates immunity for 90 days" or "6 months" or whatever would turn out to be false. The media played up anecdotes of reinfections but there was never any actual data.

The thing is they never lied. At the time they made those statements the virus had only been studied for that long.

By the time the vaccines were created the "reinfection" idea was entrenched (even though not proven) and the vaccine was recommended just in case.
