Just because Trump wanted to be popular and tell everyone what they wanted to hear, & to save his precious economy which he's ended up destroying because he won't listen to the medical experts.
 

Exactly and sadly accurate.

Paul,

Always 2 sides of the story on immunity...  While this doesn't negate King study, it shows that its only a possible suggestion and more research is needed before it is scientifically proven immunity disappears at some point in time.

-----------------------------------

But despite the anecdotal reports from doctors about patients becoming reinfected with the coronavirus, researchers say there's no evidence supporting the notion that people can become reinfected with the virus within a short time period.

"I haven't heard of a case where it's been truly unambiguously demonstrated," said Marc Lipsitch, an epidemiologist at the Harvard T.H. Chan School of Public Health.

For instance, South Korea's Center for Disease Control and Prevention in one study confirmed that, among 285 cases of people who again tested positive for the coronavirus two months after receiving their initial positive test results (including some who were experiencing Covid-19 symptoms two months after their initial diagnoses), none of the patients' new samples contained enough virus particles to allow researchers to grow the virus from the samples in a lab. Researchers said those results indicated that the patients weren't actively infected with the virus, and the diagnostic tests likely had detected dead virus particles that remained in their bodies or generated false-positive positive results.

Further, the researchers noted that none of the patients who re-tested positive for the coronavirus transmitted the pathogen to others.

"It was pretty solid epidemiological and virological evidence that reinfection was not happening, at least in those people," Angela Rasmussen, a virologist at Columbia University, said.

As for studies showing that antibodies for the novel coronavirus decline over time, researchers say that's how antibodies work for a host of viruses.

Michael Mina, an immunologist at Harvard University, said although those studies have left some people "scratching their heads saying, 'What an extraordinarily odd virus that it's not leading to robust immunity,' … they're totally wrong."

"It doesn't get more textbook than this," he added.
