Earlier today we tweeted about a new WHO scientific brief on "immunity passports". The thread caused some concern & we would like to clarify:
We expect that most people who are infected with #COVID19 will develop an antibody response that will provide some level of protection.pic.twitter.com/AmxvQQLTjM
What we don't yet know is the level of protection or how long it will last. We are working with scientists around the world to better understand the body's response to #COVID19 infection. So far, no studies have answered these important questions.pic.twitter.com/DisLjWCa4U
As new evidence becomes available, WHO will update this scientific brief

Thank you @NateSilver538, @dylanhmorris, @drannehuang, @ericMstrauss, @Laurie_Garrett and others for your constructive input.
To avoid further confusion, we are taking down the previous thread on the #COVID19 "immunity passport", but you can still see it here

Thanks for this @WHO. This American loves science and appreciates you. I apologize on behalf of all reasonable Americans for the horrific behavior of @realDonaldTrump.
