Thus limiting those that are not vaccinated and making it difficult to move freely for them. The travel pass is a horrible idea, that effectively will force many to be vaccinated. That should not be the european way.

What should be the european way? I ask this as I understand your concern about politics forcing personal decisions, yet I am not finding a pragmatic workable solution to the current crisis.

As exemplified by the UK, enough people will want to get vaccinated to reach herd immunity. Then you don’t need to care about / oppress those who don’t want to / can’t get vaccinated.

Seems incredibly selfish to force vulnerable people into isolation because some people allow themselves to get absorbed into conspiracy theories about a harmless vaccine. Requiring certain vaccines for travel has been something that has existed for decades and was never controversial.

It's not a harmless vaccine. You want to mandate vaccinating people who are at no risk from the disease, and expose them to unnecessary risks. And that means children - all to protect sick people who for the most part are already isolated. They are in hospitals or sick people homes, where you can protect them in other ways. Also the comparison with other vaccines does not automatically make sense. All vaccines are no…

> At least in my country, so far recommendations for vaccinations had been "conservative" to only vaccinate against things that seem especially risky.

Well then good news, COVID-19 is "especially risky".

For those in the EU, the upcoming travel pass will cover three categories of people: vaccinated, PCR-tested negative, and recovered (i.e. positive antibody test of immunity), https://www.schengenvisainfo.com/news/all-your-questions-on-... > For travellers who have recovered from the virus: date of the positive test result, an issuer of the certificate, date of issuance, validity date The bureaucratic stumbling block…

Sometimes I think I'm living in a parallel universe. I know people who travel regularly and no one says anything to them. No quarantine, nothing. Most people on the streets here in Germany give zero fucks, groups of 5-10, no masks (even though there's a curfew between 10pm-5am due to an increase in cases). And I traveled all the way from Moldova to Germany by car. No one, and I mean no one ever asked for a Covid test…

Because in most of the cases you are transiting and no one cares. If you would have said to any of those border guards that you are coming to stay in any of those countries, they would have cared and asked for more things. Saying this as I travelled recently from Germany through 4 countries. In the destination country they asked for test, proof of sickness or vaccine proof.

The aim is to prevent the virus from clogging up the healthcare system. Countries which vaccinated all the citizens they could(e.g. Israel) already achieved that. One dose of the Pfizer vaccine costs €16, while AstraZeneca's is less than €3. This is affordable by any measure.

Astra is hard sell to people under 50, and is looking less effective against variants. The cost of Pfizer is a lot more than the per shot cost, you need highly specialised storage and distribution due to the low temperature requirements.

You get refrigerated trucks, which are already common for food distribution, and essentially a fridge that can store a thousand doses and be re-used as new stock comes in.

It's not a negligible cost but it's far from highly specialized.

I don't know why you think that's obvious. In fact, I wouldn't have expected that query to yield anything relevant, so I wouldn't have even thought to try it.

I have to agree with the previous poster, quite often citation needed is being used as a passive aggressive form of "countering" an argument (I have to admit to having used it myself). And if, like in this case, the study (which was what the poster claimed existed) comes up as one of the first results in a google search, I find "citation needed" either to be disingenuous or lazy. Just as a test I searched for "SARS-COV-1 immunity" and got quite a few relevant references as first results as well (even though not the exact study mentioned above).

This is HN, so I think we can expect people know how to search google.

ELI5, if someone is not vaccinated isn't the only person being put at risk themselves? I have heard speculation of how this could cause more variants to arise which seems to be mostly just that: speculation. Or how this can be problematic for at-risk (elderly, immuno-compromised etc) but how frequently does that happen? I am 100% confident I have not encountered any such people in the last 6 months (or well atleast f…

Read this: https://www.nytimes.com/2021/04/21/health/vaccine-nursing-ho... "An unvaccinated worker set off an outbreak at a U.S. nursing home where most residents were immunized." One vaccinated resident died.

I hate pay walls...

The consensus I’m hearing from epidemiologists is the mRNA vaccines should offer better immunity than infection. So it would seem the 8 month for immunity after infection should be a lower bound for the vaccine effectiveness.

The consensus one year ago was that immunity doesn’t last longer than 6 months (hint: it does). I’ve learned to mostly disregard “expert opinion”, especially when they’re talking straight out of their asses as in this case (we haven’t had the vaccine long enough yet to have any kind of experimentally informed view on this topic).

You already can’t walk around doing literally whatever you want just because it’s your body you’re doing it with. You depend on other people, and other people depend on you (or at least can’t avoid intermingling with you, es…

Except that the people who are worried can simply get vaccinated themselves. There may be a few people who can not be vaccinated (old and very sick), but it hardly seems appropriate to restrict billions of people just to protect those few. It would be more efficient to isolate them, which most of them probably already are (in care homes or hospitals).

Vaccines aren't 100% bullet proof. The few people effected are still people. If you were one of them, wouldn't you be fairly distraught by your point of view?

Schengen has been deteriorating for a long time. Denmark has totally ignored it and has road checks at the border for more than 5 years now and other nations have done similar (although to a less extreme extent).

I’ve been to Denmark two years ago and I have no memory of any border check. It was by plane btw, maybe the checks are different but it would be surprising. It is totally possible however that the check was so fast that I don’t remember it. Do you have any information about this ?

Can't speak for Denmark. But usually those border-checks are done couple km/miles after the border. Police will just stop "random" cars/trucks and do a "routine check".

And "random" it might be as much as 50% of the passing cars.

The European way should be to treat the EU as one country and stop restricting movement. We've had Schengen for a long time, which meant no border checks whatsoever on most borders (we were driving through without even stopping or slowing down most of the time). With this vaccine passport, Schengen is pretty much history and that removes one of the main liberties the EU was offering.

> The European way should be to treat the EU as one country and stop restricting movement.

At least in Italy, movement was restricted inside regions (sometimes provinces) of the same country due to the epidemy.

It's not nice for anyone involved, but the primary goal is to stop/limit the contagion. I'm an expat, so it goes against one of my interests, but I'm in favor of limiting border crossings, unless you can show that you won't spread COVID around.
