Antibodies, these are the proteins our body makes when we are exposed to an infection.
We make basically two kinds of antibodies in response, we know that people who have been infected with covid-19 can make these antibodies but, we don't know whether that equates to short term or long term protection, immune-wise, we don't know how long that may last and we don't know with all these tests that are flooding the market right now with roughly only four authorized by the FDA, we don't know how accurate they are, so if you get a false positive, because these tests pick up antibodies from other coronaviruses, like the common cold, that could give you a false sense of security and protection that could potentially endanger your health, because it might change your behavior.
There is so much we are still learning about this, in science, it is so important to say what we know and say what we don't know and this virus is teaching us every single day what we don't know.
We don't know how long immunity will last, it could be two weeks, months, some say a year.
We also don't know of the people who are asymptomatic, or have shown no symptoms, or very mild symptoms, again, that is the iceberg under the surface of the water, those people have not brought themselves to medical attention, and therefore have been untested largely. We don't know if those people make the same types of antibodies, at the same levels, whether they get any immune protection at all so
This is all being studied in real time and data being collected literally day by day.
We don't know the accuracy of these tests whether they give false negatives or false positives, which is very common whenever you do a test in medicine or science.
And the other important thing about antibodies is, if I test you today, those results when I get them back, let's say in a week, are only valid for today, so I don't know that if it shows that you haven't been exposed that you don't go out right after giving your blood and get exposed the next day, I don't know whether we tested you in the lag period between where your body makes the different classes of antibodies.
Flood of new testing, finger pricks, one drop of blood, 10 minutes
We want to make the tests accessible and affordable as a home pregnancy test and test tens of millions of people. But you shouldn't do a test if you don't know what you are going to do with the results of that test and right now we don't have the answer to that question.
Then the conversation goes on to talk about opening up the country, the resurgence of the virus, the curve, nursing home residents, contact tracing
