A study in Spain of 60,000+ people indicated 5.2% of the population has antibodies to COVID. Additionally, 14% of participants who tested positive for antibodies in the first phase of the study, did not have them at the end of the study which lasted 3 months. People who were asymptomatic were the most likely to lose their antibodies.


In addition to being miles away from "herd immunity," we still have very little understanding about whether being infected gives any individual immunity and for how long.

Herd immunity will be impossible without a vaccine. We're closer to the antibody understanding tho. Hoping it goes well. https://www.cnn.com/2020/07/06/health/regeneron-coronavirus-antibody-drug-bn/index.html
 
Food for thought ....

I'm guessing if you check Dr Tom's funding you'll see some Chinese donors...lol
 
Interesting hypothesis:


"
This piece of the genome, which spans six genes on Chromosome 3, has had a puzzling journey through human history, the study found. The variant is now common in Bangladesh, where 63 percent of people carry at least one copy. Across all of South Asia, almost one-third of people have inherited the segment.

Elsewhere, however, the segment is far less common. Only 8 percent of Europeans carry it, and just 4 percent have it in East Asia. It is almost completely absent in Africa.

...

The new data showed an even stronger link between the disease and the Chromosome 3 segment. People who carry two copies of the variant are three times more likely to suffer from severe illness than people who do not.

My mates company and some of the Wac PAC came up with this...

That's pretty cool. Similar apps have been implemented with success in other places as well. The usefulness of such apps is largely dependent on hitting some critical mass of users, but once you do its far more efficient than traditional contact tracing.

Many places in America have delays in test results of 5-7 days, and they have more new cases than they can possibly hope to contact trace. By the time someone has an interview it could be 10-14 days (if ever) which means the number of contacts to trace is so much higher than if it was caught quickly. Not to mention even people who are interviewed promptly are refusing to provide contacts of people who attended parties.


I know people worries about privacy, but we need to use technology so much more than we currently are. If we had a system that could push notifications to anonymized users there would be no need to lie or hide contacts from breaking guidelines.

I came home from work and my Mrs said did you fckn hear about the app A B & C put out..? don't tell me you have it.... Then she said it's poping up on people's phone without them downloading it.... Is that possible?

A few days ago on here someone shared coverage of a Swedish study (think it was a BBC article) finding that twice as many people had T-cells for immunity compared to antibodies. Meaning possibly up to half of those infected lose antibodies but retain immunity through T-cells. That would make this news slightly less bad. Would be a shame if we're testing for the wrong thing though...

Another mention of T-cells today, here:
Haven't seen much else on this topic though. Medical experts among us, any view?

From my limited understanding, antibodies prevent the virus from infecting your cells (lock onto the spikes & clumps viruses etc).

T-cells will clear an infection but not stop the virus from infecting cells.

So the former in theory stops you getting it again, and the latter doesn't, plus also the possibility of been infecious & spreading it to others again.

But again so much unknown. Asymptomatic people (up to 80%) appear to have little to no antibody response, and what could happen is the virus staying in the population reinfecting people with low/no antibody response.

We'd then have to hope it follows normal pattern of mutating to become less lethal and not other way around (becomes a common cold type thing). But does mean those at high risk need the vaccine first, and hope they do produce a strong antibody response to the vaccine.
 
I'm getting an antibody test in work soon (nhs), it was made clear more for research purposes on how the disease spreads and NOT to suggest someone with the antibodies are now immune, as they simply just don't know that.
