Just read an article about the vaccination program in Israel, it seems like the efficacy of even the highest regarded vaccines (pfizer/moderna) is a little dubious for now, not to mention that there has already been a lot of concerns in Australia regarding the proposed AstraZeneca vaccine's efficacy. One can only imagine, that a way to confirm the effectiveness of these vaccines would be checking for an antibody response in people who have been vaccinated. I wouldn't be surprised if the granting of an "Immunity Passport" or whatever they call it would be tied into the results produced by the antibody tests and not just a vaccine certificate.

Looking forward to the news of the FDA/ICMR approval for AT1's antibody test in US/India. We might gain some serious traction on these fronts once approval is granted.
