This bullshit about immunity lasting only three months is everywhere tonight. It& #39;s a total misunderstanding.
What the CDC said: people are unlikely to get reinfected in the first 3 months.
What the news reported: people *are* likely to get reinfected after the first 3 months.

I posted about this in more detail in a response to ABC News.

Oh for fuck& #39;s sake, now Twitter itself is in on the game. https://twitter.com/AlanVRK/status/1294410214574350336">https://twitter.com/AlanVRK/s...
I am curious how this mistake ended up on all of the media channels. I personally don& #39;t think the CDC statement is that misleading. It doesn& #39;t even make claims about duration of immunity; it makes a recommendation that has a duration in it.
I don& #39;t know how you turn that into a story about new scientific evidence. And if you do, I don& #39;t know how you get the direction backwards, confusing "immune for at least three months" for "immune for at most three months."
The words "up to" in the CDC guidelines don& #39;t help.

So do the news outlets just copy one another?
Because that seems to be the parsimonious explanation for the ubiquity of a rather unlikely mistake.

CDC has now issued a clarification. To my surprise, it does not address the misperception that immunity goes away after 3 months. It merely stresses that CDC is not asserting that reinfection is impossible during the first three months after infection. https://www.cdc.gov/media/releases/2020/s0814-updated-isolation-guidance.html">https://www.cdc.gov/media/rel...
