How will these vaccines that don't produce immunity lead to less severe variants? If they mute severity of illness they will lead to more severe variants. This is basic.

They do provide immunity in 95% (conservative) of cases, so it massively reduces the population that mutations can happen in.

  They reduce severity of illness, and don't produce sterilizing immunity and eliminate transmission. And that's the problem, if you pick up a nasty mutation but because of vaccine you are able to still function, you are more likely to be out and about spreading it. And when your limited immunity wanes in a few months this mutinous bastard copy you pushed on the masses may come back to bite you in the ass. Maybe not though if you got your booster in time and if they designed it to match. Better hope your country went with the gold subscription.

    What data are you referencing to claim that the vaccines do not provide some immunity? But importantly, the vaccines do reduce transmission. See the below study along with others. https://www.nejm.org/doi/full/10.1056/NEJMc2107717 https://www.nejm.org/doi/full/10.1056/NEJMc2107717 Admittedly, one weakness of the above study is that it took place before Delta was widespread. There isn't a lot of data yet on how much the vaccines reduce transmission with Delta, but the likelihood is that they still do even if to a lesser degree.

      Reducing transmission isn't good enough! If you have an R naught above one you're still in trouble. It's common knowledge that countries with highest vaccination rates have spikes in cases right now. Israel and Gibraltar for example. Herd immunity for this was always impossible.

        Israel isn't among the countries with the highest vaccination rates anymore, quite a few other countries have overtaken it.

        Ok well you can't beat Gibraltar at 99%. But you look at other countries. New Zealand is a good one. Their hospitals are getting swamped with kids right now with severe RSV. Why? They've had their immune systems degraded from some of the most severe lockdowns I the planet. And admittedly they aren't in a covid spike but the effective lockdown has created other problems.

        This shouldn't be down voted. It appears to be correct and is a subject of active concern in NZ. https://www.auckland.ac.nz/en/news/2021/08/02/fight-against-rsv-flu.html https://www.auckland.ac.nz/en/news/2021/08/02/fight-against-...

        I down-voted because that has nothing to do with a "degraded immune systems". Many of the more common respiratory viruses also died out in New Zealand with the quarantine. Kids never got a chance to develop immunity to those particular diseases previously and now it's coming on in a wave as they are reintroduced. It's not that their response is special, in normal circumstances kids would have gotten sick and been hospitalized, that it's happening all at once is.
        swader999 5y ago
        No, they would have stronger immune systems from repeated exposure without the extreme lockdowns NZ introduced and less hospitalizations. Respiratory viruses don't die out, they can persist in animal populations indefinitely. Sars Cov2 antibodies detected in 40% of NE deer populations for instance. Not to mention cats and dogs...

      The original clinical trials didn’t measure immunity, and, in fact, the claim from day one has been that the vaccines were designed to reduce serious disease and death.

I heard against the Delta variant, RNA vaccines help divide the chance of contaminating others by at least two, even if you're asymptomatic (because basically, the virus last half the tine in your body). And also, since you're contaminated for less time, there is fewer chance of a variant popping out of a vaccinated person. Take it as someone who heard someone talk about it, did not research himself (because i don't really care) and isn't really sure of what the truth is. See this comment as a clue if this stuff interest you.

  Halving is not good enough when the infectivity is very high. The Vietnam study showed that 49/69 "trained doctors and nurses" gave the virus to each other despite being vaccinated. God only knows how many patients they infected. see https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3897733 https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3897733 for details. (But this is HN, and I will be downvoted into oblivion. Carry on folks. Keep ignoring the data.)
