I recently did a write up [1] of the Lithuanian vaccine certificate after finding a flaw on it.

What impressed me was that the verification was done fully offline in a privacy preserving way

Not sure why you are downvoted.

Health officials in US have done a phenomenal job showing how incompetent they were during this crisis. From initial downplay, then the mask fiasco, then trying to covering up the lab leak hypothesis, and of course politicizing the vaccine release timeline, they have blood on their hands. Then to say we need to blindly trust them on what they are saying on safety profile of the vaccine, its completely crazy. And through it all they never said we are sorry.

I will never trust US Health Authorities anymore. Period.

As someone who has my yellow vaccine passport from the WHO because I travel to South America, I disagree with this sentiment. I view this move by the EU more akin to TSA than the yellow fever vaccine. I believe it will turn into strictly an annoyance to travelers. The premise of TSA was straightforward response to a bad thing that occurred and turned into a useless beast and these programs appear to have the same fingerprints. For example, what is different now than before when we didn't require proof of seasonal flu shot (or any vaccine for that matter)? Are we admitting this was a mistake? If so, then why just COVID? Add MMR, DTaP, and seasonal flu to the list. Is this a temporary program until COVID-19 is sufficiently vaccinated against? If so, why is this not the first thing mentioned? What about new variants of the disease? Will we need booster shots every year? If so, then we've already significantly diverged from the yellow fever program. If this is only COVID-19, then why even bother with the program? Inevitably, I believe the program will turn into TSA and have scope creep and will never get abolished. They will continue explaining the need for their existence to keep their jobs at the detriment to only travelers. The only way I could get behind any such program is a clear end date written into law.

I think the cat is out of the bag for the US at this point. My understanding is many (most?) states did not require ID and you could provide any name you wanted.

The vaccine cards are easily faked so at this point, what proof so people have they got the vaccine? If you got it at Kaiser or UCSF it’s probably in your records, but beyond that?

I’m guessing that people will need to get a vaccine antigen test to prove immunogenicity and then get that officially certified.

There are people in the travel community who oppose restrictions, sometimes hyperbolically so. For the last year, travel forums have been full of posts by people who intentionally chose destinations because not only would those country let them in, but mask-wearing and distancing wasn't really enforced there. With regard to need to prove vaccination, note that the WHO yellow-fever certificate was originally good for…

I have my Covid shots entered into the WHO yellow vaccination passport and assume that's good enough for the time being until a specific "QR code passport" is released. edited to add: Why should a civilized country just revoke certification once you're fully vaccinated?

Not to get get too conspiratorial, but it looks like the Sinovac vaccine is less effective. As new variants come out, the requirement may not be a Covid vaccine, but a specific Covid vaccine. And that data might come out after you already have your shot so requirements for entry could change real time.

I am in that category. Few months ago I went to Egypt because they do a cheap PCR tests on the border and masks aren't really required there. For my next trip in few months, unless things relax, I am planning to go either to Zanzibar or Mexico. I don't want to bother with these apps, getting certifications, tests, quarantines.

I highly recommend Mexico. Beautiful, affordable, friendly people (especially if you make an effort to speak at least a tiny bit of the language)

That would seem like it's a stereotype for a reason, but at the beginning of all this mess, we had plenty of tourists (Ireland) who .. weren't malicious about it, they just ran on the assumption that restrictions were for everyone else. Like they're special, and obviously it's okay for them to bend the rules, as long as everyone else isn't.

I've read of plenty of people visiting Iceland recently, where it's essentially test at the border then shelter in place until you get your results. And people quite happily listing off the spots they visited on their way to their hotel to shelter in place for the evening. And to be frank, Iceland does seem to be as accommodating as possible while understandably protective of their near-zero rates. It doesn't take a whole lot of effort to reciprocate by acting as a guest should.

I don't want to sound overly critical, but it's not just the rabid fanatics. I do get the impression plenty of perfectly reasonable American tourists believe they're a special case.

We Swiss people are also quite suspicious with this kind of documentation (Google Fichenaffäre / secret files scandal for reasons). To my understanding you will get this Covid certificate either through vaccination, after having had Covid-19 or after a negative test. So it's not like a central vaccine database or so. (Note that we had such a database called "Elektronischer Impfausweis" but it had to be taken down aft…

Americans are far more distrustful. The idea of registering with your local municipality is downright alien in the United States. At best, you're required to eventually update your drivers license when you switch states, which (depending on the state) is the equivalent of "maybe" updating your license and vehicle registration whenever you eventually get around to it. Compare that against moving between, say, Switzerl…

Americans are distrustful, but every birth is registered, nearly everyone gets a license and everyone gets a Social Security Number. Of course, none of these are centralized databases or required to be updated often, so the government knows you exist but doesn’t necessarily know much more than that.

They pretty much have to keep this short. Anything more permanent and you open up the risk of "alternative" databases being build by nefarious third parties.

How does a short lifetime of the certs help with 3rd parties building these databases you mention?

Once the certificate becomes obsolete, it becomes useless and therefore needs to be reacquired. Same process with American SSNs, if they were depreciated very 6 months getting yours published wouldn’t be an issue.

British Colombia is wary of them on the basis of inequity, which is not unreasonable, that said, they may be doing something for international travel. The Swiss thing looks kinda complicated, and likely hard for other countries to participate. Easy Solution: issue a passport insert + seal. Go to the hospital/clinic, show your passport, they give you a seal, a stamp, a number, and a signature. The number can be typed…

It‘s basically a PKI and this design was chosen with the explicit goal to participate in the EU Green Pass project with the goal that all EU members can participate in the same system. When the the system stands the only bureaucracy will be for an issuer to get a cert from the authority or for an authority to be included in the root. All the things you describe with the seal and number and system to validate is just…

The difference is there's no hard dependency on centralized authority or any kind of complex web or mobile technologies.

IT is complicated. Many orgs are still running ridiculous old systems. A lot of people don't have mobiles phones, or generally don't know how to use them properly, may not have data services or even an email address. The 'COVID tracer' app issued by gov. Canada has barely anyone using it.

TN visas (NAFTA visas for US/Can/Mexico) are obtained at the border, it's just something stapled into your passport. That's it. And that entitles you to live in a foreign country. We could feasibly do the same with COVID tags.

It's really hard to set up government agencies that operate effectively with all the bells and whistles, it's costly, tons of consultants, tons of service calls & support ... by leveraging the DMV or it's equivalent, you already have most of the infrastructure in place: they know how to check and issue IDs, they have processes for appointments, service calls, queuing, putting out support content that meets standards (i.e. disabled, elderly), actual phone numbers and physical people to speak to for those who are used to that. For the same reason bank tellers still exist.

We used to do some amazingly complicated things without IT.
