but they are getting infected with Covid (which isn't so great). The US approved vaccines (so far) appear to be pretty good at preventing infection compared to lots of vaccines. There's an obvious level of (incomplete) protection present in the population at 50% vaccination. Cases aren't falling because we are getting more careful (but then the nicer weather could be helping).

FWIW, Singapore uses Pfzer-BioNTech and Moderna. There's a scary situation happening here now for the last 2 weeks or so. There has been new clusters popping up after having been relatively tame for a few months and safety measures have been tightened (slightly, but obviously) again. Some of these cases involve those that has been vaccinated. One lesson that we can learn from this is, coming from a city that is marke…

Exactly. It's clear the vaccine protects the people who receive it from serious disease. But people who are vaccinated can get infected and infect others. Therefore we won't see much "back to normal" until most, if not all, people are vaccinated. This wont be one of those "60% and we hit herd immunity" situations.

> The travel pass is a horrible idea, that effectively will force many to be vaccinated. Good. It’s not like a concentration camp. There are other options if you don’t want to vaccinate. You can just stay at home (I’ve been declined Schengen visa in the past for no reason), you can get PCR-tested. You also can get ill with Covid and then recover (hopefully).

Do labs store collected DNA results of PCR? I wonder if a database of DNA of millions of people will emerge on black market one day.

Why bother with PCR? You can do the same with any blood test included with any routine checkup.

I had this exact question and asked around before finding out a friend's brother specializes in immunology. Apparently two separate exposures triggers a much longer lasting immune response, and because of the nature of the vaccine it's much more targeted to one specific aspect of the virus, and consequently more potent in a way. Moderna also made a statement that they expected their vaccine to last for 2 years based…

Yes. So long as no mutation takes place on the protein spike.

Depends on the significance of the mutation. The vaccines have shown to be pretty good at protecting at the mutations we have observed so far. However, it is right to assume, that eventually a mutation comes around which evades any existing immunity. That is one the biggest reasons to reduce infection count globally. The higher the infection count, the larger the risk of a mutation that resets everything back to the beginning immunity-wise.

Isn't is possible for someone to stab you? So in theory you could have some small degree of worry about your safety. Different people have different places they draw the line for an acceptable amount of worry vs an acceptable amount of freedom restrictions.

The potential exists for DNA harvesting. Dismissing it as impossible seems inaccurate. >(CBS) — The largest biotech firm in the world wasted no time in offering to build and run COVID testing labs in Washington, contacting its governor right after the first major COVID outbreak in the U.S. occurred there. The Chinese company, the BGI Group, made the same offer to at least five other states, including New York and Cal…

I haven’t opened your first link, second looks like pure conspiracy theories. Covid, China, Bill Gates, Epstein!!11 If you’re afraid of getting your DNA sequenced while doing PCR test, please read up on the process of test, equipment, materials and costs involved.

The source is CBS news.

>"I haven't bothered to read, but I'm dismissing it as a conspiracy theory"

I hope you can appreciate the problems with that reasoning.

Yes, there are costs involved in data collection. If the data is valuable, organizations will foot those costs. We've seen this in the tech sphere. Why is it hard to imagine it in the health/biosecurity realm?

This is getting stupid, if it wasn't already.

Requiring vaccination is "curtailing liberties".

Restricting movement due not being vaccinated is "curtailing liberties".

No shit. One can either be part of society or not. Society has minimum requirements if one wants to participate. One is free—exercise their liberty—to live as a hermit if they don't want to do either of these things. That's the price of admission of getting the benefits, whatever they may be, of interacting with other people. Added bonus, the rest of us don't need to hear about hermits complaining about their liberties then too.

Building sewage management infrastructure is not curtailing liberties. There is very little noise made about having to give up liberties because of the majority of other public works. Civilization decided that shitting on the sidewalk is not something that should be encouraged or condoned, so here we are with our sewage management infrastructure. We gain the freedom of not having to dig a hole and maintain an outhouse.

No one is giving up any "liberties" by getting vaccinated, but it's more likely they are acquiring liberties by getting vaccinated. At the very least it's the liberty of reducing the risk of dying.

This is all a "I don't want to do what you said I should do purely because you said it". Fine. The rest of us are at liberty to exclude or chastise these people.

In (most of) the EU, it’s illegal to carry a weapon of any kind unless you have a reason to do so (ie, going hunting). You can’t even carry pepper spray.

It's a shame your comment has been found to be polarising, I think your phrasing is quite moderate.

Looking at social media it feels like too many people are celebrating because they've been given another opportunity to show how virtuous they are. They're not one of those people that oppose vaccines and progress, oh no. The clout associated with putting up pictures of you with a needle in your arm is probably the most off-putting thing I'd gotten to gawk at.

My assessment is similar to yours. The situation just kinda is. We've had a novel viral agent, what followed is what you'd expect of a society that optimised for lack of novel viral agents. Now the viral agent is mostly gone and we have two new taxes to show for it: further encumberement of civil liberties and more revenue for the pharmaceutical industry.

It's not a bad result but there's no big win to point at either

Is that within the margin of error for false positive tests? IOW, maybe the 1 in 1000 didn’t actually have COVID the first/second time?

Reinfection is not rare, Singapore has detected 26 cases of reinfection so far: https://www.straitstimes.com/singapore/politics/parliament-2... Also note worthy: recent infections in Singapore includes "56 cases involving people who were infected despite being fully vaccinated"

Reinfection is very rare. The Israeli study is the most reliable, but going by your data point of 26 cases of reinfection and the ~61,000 cases[0] in Singapore, we're talking 1 in 2,500.

It's moronic to get the vaccine if you've recovered from COVID. The reinfection rate is 1 in 1,000, and even then it's all mild cases. (https://www.medrxiv.org/content/10.1101/2021.03.06.21253051v...)
