Damn! That is not good news for vaccines.

A person who has recovered from COVID-19 will likely be safe from reinfection for three months, according to updated guidance from the Centers for Disease Control and Prevention (CDC).
The information marks the first acknowledgement of a defined immunity period for people who have recovered from a COVID-19 infection.
Prior research has shown antibodies from recovered patients will fade over the course of a few months, but federal scientists had not previously said what that means for immunity.
The CDC previously recommended that someone recovered from a COVID-19 infection doesn’t need to be tested again for three months so long as that person is asymptomatic, but made clear that any correlation to immunity was still unknown.
The CDC did not make a formal announcement of the findings; rather, the information was included as part of broader guidance about quarantining that was last updated earlier this month.
According to the agency, people who have been in close contact with someone who has COVID-19 need to quarantine for 14 days, except people who have had COVID-19 within the past 3 months.
“People who have tested positive for COVID-19 do not need to quarantine or get tested again for up to 3 months as long as they do not develop symptoms again. People who develop symptoms again within 3 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 said.
We have heard some information similar to this in the past few months but this is the first time it has been detailed so specifically.
My first concern, of course, is that this means a vaccine would prove impossible since the antibodies do not seem to last very long in the human body.
My other concern is what does the second, or third Coronavirus infections look like?
I mean do we weather reinfection better, without antibodies that don’t seem likely, or does our compromised immune system then make us more susceptible to a more severe reinfection?
It seems to me that masks and social distancing might be here to stay.
Update: The CDC issued a clarification because they felt the media was misreading their initial guidance.

On August 3, 2020, CDC updated its isolation guidance based on the latest science about COVID-19 showing that people can continue to test positive for up to 3 months after diagnosis and not be infectious to others. Contrary to media reporting today, this science does not imply a person is immune to reinfection with SARS-CoV-2, the virus that causes COVID-19, in the 3 months following infection. The latest data simply suggests that retesting someone in the 3 months following initial infection is not necessary unless that person is exhibiting the symptoms of COVID-19 and the symptoms cannot be associated with another illness.
So if I am reading this right it appears that the CDC is unwilling to identify any time after being infected that somebody is actually safe from reinfection.
Hell, that is even worse news than what the initial article led us to believe.
