That may be true. But it doesn't change the fact that we will likely need some way to see who is immune and who is not - whether its the result of a vaccine, more reliable antibody testing, etc.
People are welcome to protest data privacy. They're welcome to claim that we have no way to implement it, even though we already did for yellow fever. While some people are paralyzed with indecision, others will happily get a test/shot and their certificate so they can get on a plane.
Decision. Consequence.
I’m not talking about a vaccine nor data privacy. I’m saying that a very limited test for people traveling certain ways is very different than a test that in some cases will be faulty and is applied globally to reduce rights like working for people. And you selectively quoted me by the way.
