Boeing 737 max has a lower crash rate than cars, do you think the ban was warranted?

Cars should also be banned and replaced with alternatives (be it safe self driving tech, public transit or biking). Car crashes are one of the top killers of young people in terms of crashes, and we’re just starting to understand the effects of air pollution on young lungs.

Or maybe stop banning things and let people make their own decisions.

The rate of blood clots as a side effect for the AZ covid jab is less than that of the combined contraceptive pill - does that mean that both need to be discontinued?

Maybe I've missed it, but I didn't find anything in the article about whether the vaccine does need to be discontinued or not. In any case, being clear about what side effects are possible and researching them to get a better understanding is a requirement in my opinion.

You need to read the VG articles, they are much more thorough than the one linked on HN but they are in Norwegian. Google Translate does a fair job.

A key quote from the second of those is this:

Madsen har tidligere forklart at det er to nivåer å undersøke bivirkninger på: Gruppebasert, og individbasert. Ifølge Madsen det ikke er noe som tyder på at AstraZeneca-vaksinen er forbundet med en større risiko for blodpropp i statistikken – men det de undersøker, er om det kan finnes bivirkninger som er spesielle og rammer få personer.

My translation:

Madsen has earlier explained that there are two levels of investigation regarding side effects: group based and individual. Accoeding to Madsen there is nothing to indicate that the AstraZeneca vaccine is associated with a greater risk of blood clots in the statistics - but what they are investigating is whether there are side effects that are special and affect few people.

That's an odd sample to use unless you have some sort of agenda. The 40 out of 17MM is much more statistically significant.

If you give a vaccine to 17 million people and 40 of those are children and all 40 children dies then should we just ignore that fact because the "40 out of 17MM is much more statistically significant"? Of course not.

That's the epitome of a gross exaggeration.

The clotting with AZ is very different and more serious than what the thrombosis associated with the pill - about half of those who get it die even with best medical care. It predominanctly affects folks who would have a miniscule risk of death by Covid19, so this absolutely needs to be investigated.

Yep, this^ is the point. It is amazing that this key point is missed in so many discussions. Now.. maybe it is still worth the risk for a young 20 year old female, but I am not so sure - especially since we luckily have other vaccines that do not show this risk.

There are safer vaccines so there is little point in risking this one. That said, it depends on how many future infections people that age face.

If this vaccine is causing at most 4 deaths per million people* vs 648 recorded US covid deaths 15-24 out of a population of 43.5 million. 4 * 43.5 = ~174 https://knoema.com/atlas/United-States-of-America/topics/Dem...

So if the total future infections are say 1/4 the total infections up to this point then their roughly equivalent risks. Tipping one way or the other based on actual number of infections.

* It’s rare enough that actual risks aren’t clear, but assuming the vaccine is the cause we can assume the risks are at or below that level.

Criminals aren't arrested for breathing. Next!

Again, that's comparing apples and oranges. Not to mention, what's the cost-adjusted safety comparison look like, given that a 737 costs more than a thousand cars!

Your whataboutism needs some work.

It's still too early for the general public to draw conclusions from the data provided. Derek Lowe had some early observations on these numbers and their significance in regards to the critical missing data needed to make decisions: https://blogs.sciencemag.org/pipeline/archives/2021/03/16/wh... > "...they say that is indeed “ much lower than would be expected to occur naturally in a general population of this size “…

Derek did a good job on this issue, both warning it would happen before and re-emphasizing that it's most likely statistical anomaly. Even if the blood clots were a result of the AZ vaccine, it would still make more sense for most people to take the vaccine (I would), so a ban is entirely unjustified. Governments banning their citizens from taking Astrazeneca should use accurate language "it's banned" instead of the…

> Governments banning their citizens from taking Astrazeneca should use accurate language "it's banned" instead of the language "pause rollout".

Pausing is exactly what is happening here in Norway. And the government is not involved, all these decisions her in Norway have been made by the relevant medical institutions.

hes a clotting expert, not a COVID expert. So of course he sees clots everywhere. Are you sure he's the spokesman, or just making this claim as an independent researcher. There is nothing in the two articles I read saying this is an official position of the hospital.

Yes I'm definitely sure he is speaking for the hospital, and that he was speaking at the hospitals press conference. This has been all over the news here in Norway, every news outlet treat this as legit, and from the hospital / government.

acknowledged. I did some more searching and found several articles where the hospital seemed directly involved.

It’s said in many texts about this (possible) problem, but I don’t understand how serious blood clots and low levels of blood platelets can go together.

https://en.wikipedia.org/wiki/Platelet: “Platelets […] are a component of blood whose function […] is to react to bleeding from blood vessel injury by clumping, thereby initiating a blood clot.”

So, I would expect low platelet counts to be associated with excessive bleeding, not excessive clotting (and indeed it is. See https://en.wikipedia.org/wiki/Thrombocytopenia)

Do most platelets for these patients end up in clots, and is production stopped? Are there other cell types or mechanisms that can cause clotting? Can anybody enlighten me?
