I don’t know much about the passports but my family and I are part of the testing for a non-RNA experimental vaccine. I am pretty close to the R&D folks and receive a lot of the regulatory data as part of the study. It is very much a vaccine and at least this one is made in the traditional way and it works. I’m happy to share more info if you’re open to hearing how the sausage gets made. The EUA vaccines are part of the Federal countermeasures program which does limit one’s remedy in the rare event of injuries. I say rare because the folks who were a few months ahead of me in the development cycle agreed to get dosed with about 5x the normal amount to test for toxicity and they’re still alive and kicking. As strange as it sounds, the best way to ensure the drugmakers have to support you if something goes wrong is to enroll in the trial. You and the company both sign a legally binding contract where they have a fiduciary duty to provide free medical care to fix whatever happens.
