[quote CoffeeandCroissant]over the past few days I have seen a few people (on here and FB) gleefully stating that immunity has apparently been 'proven' to only last 3 months?
I think it is either a misunderstanding or deliberate misrepresentation of the CDC guidance, see below.
“People who have tested positive for COVID-19 do not need to quarantine or get tested again for up to three months as long as they do not develop symptoms again. People who develop symptoms again within three months of their first bout of COVID-19 may need to be tested again if there is no other cause identified for their symptoms,” the CDC website reads.
Confusion over what this new guidance means in terms of COVID-19 immunity is rampant. Some online commenters and media outlets mistakenly took the CDC’s update as a confirmation that people with COVID-19 are immune from reinfection for up to three months.
Then a backlash formed, particularly among the epidemiological community on Twitter. Many experts said various news outlets were misinterpreting the update. Instead, the general scientific consensus is that coronavirus immunity lasts at least three months, not a minimum of three months, experts such as Carl Bergstrom, Ph.D., a professor of biology at the University of Washington and coauthor of the forthcoming book Calling Bullshit: The Art of Skepticism in a Data-Driven World, said on Twitter. In fact, the New York Times reports that the latest research hints that people retain “strong, lasting immunity” even after mild illness with COVID-19. That research is still in its early days and doesn’t specify how long, exactly, this immunity seems to last, but many experts do find it encouraging, according to the Times.

Ah thats interesting. A world of difference between 'only 3 months' and 'at least 3 months.
However, it doesn't sound too much like its a consensus on any immunity(even short term), as otherwise even with symptoms, people wouldn't need another test IF they had had a previous one within 3 months, if that makes sense?
Though as admitted, my science-y knowledge is basically 0!
