Tuesday on Rachel Maddow, Ari Velshi, standing in for Rachel, addressed a question to DR. ASHISH JHA, (K.T. Li Professor of Global Health at the Harvard T.H. Chan School of Public Health and the Faculty Director of the Harvard Global Health Institute) that answered a question I have had about our immunization passport. Are there antibody tests with the necessary efficacy to validate the reliability of our passports? Without a reliable antibody test there is no reason for people to put their trust in what we offer. This is the relevant portion of the transcript:

VELSHI: Now, the Abbott test that we`re discussing, that is a test that is

given to people at the White House to see if they have coronavirus at the

moment. There is also this antibody testing that I think a lot of people

are eager to get, because they want to know if they were exposed to

coronavirus, do they have some immunity, can they get back to work. I think

we`re all eager to get back to some form of normalcy.


Are they reliable?


JHA: Yes. So some of them are. Look, there are probably 70 different

antibody tests out there. But three or four of them actually are quite

reliable. So, it`s really critical if you`re going to get this test through

your doctor, to make sure you`re getting one of those.
