The current attention focused on antibody tests and immunity passports suggests they might be the answer to safely returning to normal life, but it might not be that simple.
When a body is exposed to a new pathogen, part of the response launched by the immune system is the production of specific antibodies, which are present in blood after infection. The reason everyone is so interested in antibody testing is because for many diseases, antibodies indicate immunity to that pathogen. However, it’s not yet clear whether SARS-CoV-2 antibodies confer immunity to COVID-19.
So what can antibody tests tell us, and where can we go with an immunity passport? And what are the alternatives if antibody tests don’t tell us what we need to know? Today in The Conversation Canada, immunologists Shayan Sharif and Byram Bridle of the University of Guelph share insights into the promises and pitfalls of antibody testing.
