We have clear scientific consensus on the fact that vaccines reduce the negative effects of getting COVID, and reduce the likelihood of getting COVID in the first place. So declaring that vaccine mandates won't affect populations 'because you can still get it' is effectively twisting the truth. Or at least applying some really bad logic. The link you provided is unfortunately not helpful. Again, there is overwhelming evidence that actions taken by governments were successful in most ways in preventing spread during the pre-vaccination era. Huge spike is case rates were immediately neutralized by lockdowns etc.. The moral and legal case is ambiguous, but not the overall effect of the policies was clear. In my area, we had two huge spikes, after which there were lock-downs declared, and immediately the case rates dropped dramatically. I'm wary of the civil issues, but the results were clear. The article provides no evidence that vaccines don't work, other than to indicate that protections against Delta variants is weaker, which we already knew. This statement: "The principle defence against a respiratory virus actually takes place in the mucosal membranes of the respiratory tract, and the high proportion of those with some degree of natural immunity fight off SARS-CoV-2 there, preventing it replicating significantly in the bloodstream. Therefore, it is not actually surprising that a vaccine which works mainly in the circulatory system has little effect on stopping what starts as a respiratory infection. If that is the case, it is illogical to expect any reduction in transmission." Is hugely speculative, not Scientific. The author of this piece failed to play their own devil's advocate because there's tons of data to debunk most of what he is trying to say, in a nutshell, the author is cherry picking.

I don't doubt the vaccines are effective at reducing negative effects on the vaccinated individual. Nothing in my comment above was intended to imply that. The specific point I was trying to make is that there is conflicting evidence that the vaccines reduce transmission. Since governments around the world pushed vaccines for everyone partly on the hypothesis that it should reduce spread, this is a big problem. The truth about transmission reduction from vaccination is therefore in my mind critical. And so far from what I've read, there is not yet a clear scientific consensus on whether vaccines do indeed significantly reduce transmission. And for the record, in case anyone is wondering, I'm not a tunnel-visioned troll. I welcome being shown studies that do (or don't!) demonstrate reduction in transmission, which I will read and digest before the next HN debate on this topic. It's only by scientific inquiry and debate that we will get to the truth here.

  The consensus has shifted to the point wherein the preponderance of evidence points to reduced transmission. Here is Nature in Feb [1] Here is Nature now [2] [1] https://www.nature.com/articles/d41586-021-00450-z https://www.nature.com/articles/d41586-021-00450-z [2] https://www.nature.com/articles/d41586-021-02054-z https://www.nature.com/articles/d41586-021-02054-z

    Thanks, [2] is interesting. Sadly lacking much information on the transmissibility of the delta variant, which is the dominant strain in most (?) western countries. Such information would tell us whether achieving herd immunity without direct infection from SARS-CoV-2 requires continual application of boosters forever (i.e. for each seasonal variant). I say this because there is evidence from other respiratory viruses that, after having transitioned from animal to human, they typically mutate to become more transmissible but less deadly, which we normally deal with by letting sweep through the country without mass vaccination (only for the vulnerable).
