Coronavirus herd immunity may be 'unachievable' after study suggests antibodies disappear after weeks in some people

Fourteen percent of people who previously tested positive for antibodies tested negative just weeks later.

The study suggests people who experience mild symptoms do not have long-lasting protection.

"Immunity can be incomplete, it can be transitory, it can last for just a short time and then disappear," Raquel Yotti, the director of Spain's Carlos III Health Institute, said.

[Ian] Jones [a professor of virology at the University of Reading] added: "Anyone who tests positive by antibody test should not assume they are protected. They may be, but it is not clear."

What this also means is that a vaccine may/will not work.

3. Shhhhhhhhhhit, over 60,000 ... "received POC antibody test" This study is large. The only thing miss

... missing is the hospitalized / recovered AB testing because mild symptoms the body could be disposing of antibodies.

The didn't test if the body could make antibodies quickly either

4. "Study suggests" means research is inconclusive, merely hypothetical nt

5. Antibody tests are notoriously inaccurate and unreliable

And extremely dependent on time of administration. Over 200 different tests kits available.

Up to 30% false negative results.

7. Agreed. Also, your body remembers how to make fresh ones when challenged.

This story has been resurfacing for months; nobody ever mentions the rest of the picture.

8. Yes!: "What this also means is that a vaccine may/will not work."

Repeating your sentence:

What this also means is that a vaccine may/will not work.

DH & I have been discussing this for days now & what it means for society & the economies.
Conclusion: we must continue to isolate, wear masks, & be damn careful. Darwin's laws will rule.

9. Monoclonal antibody therapy will work.

I think that is our fastest ticket out of this mess.
