As tens of millions are inoculated against Covid-19, officials in places as diverse as New York state, Israel and China have introduced “vaccine passports,” and there’s talk of making them universal. The idea is simple: Once you’ve received your shots, you get a document or phone app, which you flash to gain entry to previously locked-down venues—restaurants, theaters, sports arenas, offices, schools.
It sounds like a way of easing coercive lockdown restrictions, but it’s the opposite. To see why, consider dining. Restaurants in most parts of the U.S. have already reopened, at limited capacity in some places. A vaccine passport would prohibit entry by potential customers who haven’t received their shots. It would restrict the freedom even of those who have: If you’re vaccinated but your spouse isn’t, forget about dining out as a couple.
Planes and trains, which have continued to operate throughout the pandemic, would suddenly be off-limits to the unvaccinated. The only places where restrictions would be relatively eased would be those still fully locked down, such as many live-event venues and schools. Yet even there, the passport idea depends on keeping the underlying restrictions in place—giving officials an incentive to do so for much longer as leverage to overcome vaccine resistance.
The vaccine passport should therefore be understood not as an easing of restrictions but as a coercive scheme to encourage vaccination. Such measures can be legitimate: Many schools require immunization against common childhood illnesses, and visitors to some African countries must be vaccinated against yellow fever. But Covid vaccine passports would harm, not benefit, public health.
