COVID-19 immunity: society will split 
into two classes until vaccine is ready. (4)

Do you think that patients who have recovered from COVID-19 will have a particular advantage in returning to work in the the first wave and resuming daily life activities? Dr. Anton Titov, MD. I do think that there is a hope that patients who have been infected, maybe they did not know they were infected because they were an asymptomatic case, will develop antibodies. Those antibodies will be protected. There are countries now doing these types of Siro surveys looking to see if patients have antibodies. Using that to stratify patients whether or not they can and social distancing. This is going to be a critical tool that we use to try and open back up economies around the world looking at the level of infection and looking to see if those antibodies are protected. Then allowing those individuals to be out and doing and going about their lives. Increasingly that will be what you’ll see more and more countries trying to adopt as serology tests become more available. Do you think that if we take a global perspective, considering the airline shutdowns, those kinds of tests will allow patients to travel freely if you have them, too? Dr. Anton Titov, MD. You’ll be more restricted or somehow marked if you don’t. Medical second opinion is important. Dr. Amesh Adalja. That essentially creates like two classes of patients in that respect. Yeah, I do think that there is a real likelihood that you do have two classes of patients, those with antibodies and those who do not. Not may be something that we have to grow, to grow with as a society. Think about how to move forward in that environment until there is a vaccine available. But I do think to suppose you are a doctor or a nurse. It is important to know if you have antibodies so that you can take care of patients in a safe manner and not be worried about your own risk of exposure. Medical second opinion is important. Dr. Amesh Adalja. I do think that this serology testing will be important as we move forward to try and get and reclaim the world. Dr. Amesh Adalja. I do think that there is this chance that there may be,, two tiers of society, those are the antibodies and those that don’t. But rapidly that will vanish as more patients get infected and as a vaccine to get developed. As we deal with the hospital capacity, because the more patients that are affected. The less likely over time Dr. Anton Titov, MD. You are going to have new cases. Dr. Amesh Adalja. That may allow patients to lift some of the restrictions because of the level of cases is enough that it is such that hospitals can handle it without going into crisis. Medical second opinion is important. Dr. Amesh Adalja. That is a very important point. Because,, maybe it is not relevant for the United States. But certainly, it is relevant to Europe. There is a lot of patients who got the first wave infections where patients skiing in the Alps,, younger age, more affluent, more,, more different social strata, especially as they return to their countries in Eastern Europe, for example. Medical second opinion is important. Dr. Amesh Adalja. That has a societal implications that now they will have the advantage of having those antibodies in a sense and can go on with their life while other patients are being sorted of psychological war if not locked up. Then those countries. Yeah, I do think that having to know that your thought that you have been exposed and that you are okay and safe. Dr. Amesh Adalja. That is going to have a great effect on patients that they are that they are then able to reclaim some of their life.
