Could we ask that manufactures create an interactive vaccine, one that could communicate with the recipient and a central health facility, giving a constant COVID infection update? As an example, if it beeps a warning, the recipient could simply report back home immediately to begin a 2-week quarantine.
DARPA the fringe boffins group is working on just such a device. My dog has a chip in her ear I don’t think it’s wise to chip humans the chip can migrate and cause a blockage in a vein or artery leading to stroke or cardiac arrest we tolerate the risk on pets but humans not so much.
