look at this from a public health perspective. If there is any doubt as to the vaccine's safety, would it cause the average citizen just to take their chance with catching COVID? Probably. Unless you are obese, more likely than not, you will survive COVID without a problem. Less than 10 percent of COVID infections result in a hospital visit, and of those hospital visits, the ones that end up in intensive care units are 80 percent of the time obese.
I take your general point, but the data suggest (see my previous link), that the risk of blood clot from taking the vaccine is less than the risk of blood clot from catching Covid. Sure you can gamble that you won't take the vaccine and will hope to avoid Covid, too... but when the number of blood clots is so tiny, so statistically insignificant as to suggest no link at all, it's a different question.
So maybe that's why Denmark banned AstraZeneca's vaccine? Not necessary because of the threat for blood clots was large, but may just to keep public confidence in the vaccine to avoid the anti-vaxers from taking up the discussion and promoting doubt in the COVID vaccines?
It's impossible to determine why they banned it, given the previous history. I'm from the UK, and was against Brexit...but with the AZ vaccine the EU has behaved terribly. We had Macron inciting anti-vax hysteria in France with his comments about AZ, we had similar but lesser issues in Germany, we had bans for people over 65, then okay for older people and bans for younger people, etc... we had EU leaders claiming the vaccine was ineffective... and at the same time the EU going crazy during the supply issue, and demanding 100% of AZ vaccines stay in the EU... even though they didn't want them, they "weren't safe" and "weren't effective". Absurd. And impossible to disentangle all of this from Denmark suddenly banning it because of non-existent blood clots.
Anecdotally, just as a point of interest (a single data point does not consititute an argument), I've had the AZ vaccine. I had mild fever/chills overnight, and a bit of a headache. Within 24 hours I was back to 100%.
