Children should not be vaccinated for the moment. There is not yet enough evidence on the use of vaccines against COVID-19 in children to make recommendations for children to be vaccinated against COVID-19. Children and adolescents tend to have milder disease compared to adults. However, children should continue to have the recommended childhood vaccines. 数据够了就会改变吧？
Guardian三周前的文章，不知道为什么昨天我搜索WHO的vaccine决定时被推荐这篇， 不过有几段挺有意思，算是多提供一些背后的考量？ Health experts urge caution on giving Covid vaccines to UK children As the US and Europe approve plans to immunise teenagers, scientists in Britain advise delayhttps://www.theguardian.com/society/2021/may/29/health-experts-urge-caution-on-giving-covid-vaccines-to-uk-children “Children transmit Covid to some extent, although they rarely suffer badly from the disease themselves. If you offer them vaccines, then you put them at risk of possible side-effects – so there really needs to be some significant, tangible benefit to them, not just the indirect protection of adults from Covid-19.” But the move to vaccinate children has been criticised by global health leaders, including the head of the World Health Organization, Tedros Adhanom Ghebreyesus, who earlier this month said that although he understood why some countries wanted to vaccinate children and adolescents, he urged them to reconsider. “In low and lower-middle income countries, Covid-19 vaccine supply has not been enough to even immunise healthcare workers, and hospitals are being inundated with people who need lifesaving care urgently,” director of WHO said. -- WHO的谭赛德认为比起儿童，应该优先为贫穷国家的医护人员和其他高危人群接种 This point was backed by Professor Peter Openshaw of Imperial College London. He said there was now “a very important argument to be had about the ethics of devoting all of these vaccines to our own population when we could be sharing them with the rest of the world”. In the US – which has led the way in giving Covid vaccines to children – this action has been taken, in part, as a response to vaccine hesitancy there, added Finn. “In America they’ve got lots of vaccine but fewer people willing to be vaccinated, so immunising children may be seen as one way of increasing population immunity. -- Imperial College London教授说美国现在决定给孩子接种的部分原因就是很多大人不肯打疫苗。 “However, it is probable they may still end up with higher proportions of unvaccinated people in certain communities and that could sustain outbreaks. By contrast, in the UK, the population – so far – has generally been very enthusiastic to be immunised, and that helps protect everyone enormously.” This situation could change, however, especially with the arrival of new virus variants, added Openshaw. “The new variants are actually spreading down into younger generations. In other words, the virus is changing its behaviour as it evolves, and you could argue that as children are becoming much more important in driving transmission, there are reasons for widening vaccination and including children.” This last point was backed by Finn, who said that if the spread of new variants caused major increases in cases across the country and triggered new lockdowns – including school closures – then it would be justifiable to begin vaccinating children. “You could justify the theoretical risk of rare severe side effects of vaccines by setting it against the important benefit of not disrupting children’s education any more.” -- 如果开放后学校出现大规模传染，政府应该会重新考虑给孩子接种。 Professor Russell Viner, of University College London, agreed: “Once we have vaccinated as many adults as we can in the UK, we can look at where we are with the spread of cases, and if we find we still have significant disease transmission taking place, I believe there will be a case for vaccinating teenagers. “By then, we will have accumulated much more knowledge of exactly how safe vaccines are, and we would be more confident about how teenagers will react to immunisation. Certainly, my feeling is that it is likely that it will eventually be safe to vaccinate teenagers, and that it is something we will do in future.”
Beyond their substantial protection of individual vaccinees, coronavirus disease 2019 (COVID-19) vaccines might reduce viral load in breakthrough infection and thereby further suppress onward transmission.https://www.nature.com/articles/s41591-021-01316-7
Children should not be vaccinated for the moment. Children and adolescents tend to have milder disease compared to adults, so unless they are part of a group at higher risk of severe COVID-19, it is less urgent to vaccinate them than older people, those with chronic health conditions and health workers. More evidence is needed on the use of the different COVID-19 vaccines in children to be able to make general recommendations on vaccinating children against COVID-19. WHO's Strategic Advisory Group of Experts (SAGE) has concluded that the Pfizer/BionTech vaccine is suitable for use by people aged 12 years and above. (这段话是说不建议给儿童打吗？还是我理解错了？诚心请教）Children aged between 12 and 15 who are at high risk may be offered this vaccine alongside other priority groups for vaccination. Vaccine trials for children are ongoing and WHO will update its recommendations when the evidence or epidemiological situation warrants a change in policy. It's important for children to continue to have the recommended childhood vaccines.
回复 1楼springday的帖子 why do you cherry-picking sentence? ! the below is the full statement of WHO, which didn''t change a WORD from june 3rd, 2021!!!! WHO SHOULD GET VACCINATEDThe COVID-19 vaccines are safe for most people 18 years and older, including those with pre-existing conditions of any kind, including auto-immune disorders. These conditions include: hypertension, diabetes, asthma, pulmonary, liver and kidney disease, as well as chronic infections that are stable and controlled. If supplies are limited in your area, discuss your situation with your care provider if you: Have a compromised immune system Are pregnant (if you are already breastfeeding, you should continue after vaccination) Have a history of severe allergies, particularly to a vaccine (or any of the ingredients in the vaccine) Are severely frail Children should not be vaccinated for the moment. Children and adolescents tend to have milder disease compared to adults, so unless they are part of a group at higher risk of severe COVID-19, it is less urgent to vaccinate them than older people, those with chronic health conditions and health workers.

你还没解释为什么总是信口开河，不停重复unsubstantiated allgegations。之前不是说去年整整11月都没mutants?
虽然不知为什么你完全当作没看见，再次复制被你之前用来"证明“你阴谋论的作者，他的peer reviewed paper已经根据prior research解释mutants的起源：

很多变种的出现是在有免疫缺陷的病人被新冠长期感染，并接受新冠治疗例如 convalescent plasma 后。 这些人被传染，就是因为当时没有什么有效控制新冠在社区传染的手段，比如管用的疫苗或者严苛的lockdown. 后来迅速传开也是因为没有herd immunity (via vaccine）或者严苛封城
High rates of mutation accumulation over short time periods have been reported previously in studies of immunodeficient or immunosuppressed patients who are chronically infected with SARS-CoV-2 (Choi et al. 2020; Avanzato et al. 2020; Kemp et al. 2020).

请问去年下半年发生了什么 让原本以为不会变异的新冠开始mutants频出？
这是现身说法复读机么？
还是说没有合理解释 直接用大水灌死别人？
又开始回收再用你那些之前没有任何证据的阴谋论了吗? 这已经是本帖中第四次，还是第五次你在没有任何证据的情况下把变种怪到疫苗上了吧，难道一句话多重复几遍会更有说服力? 这种不负责任复读机式的发帖方式也太容易了。真的跟你之前在airline operational strain等同covid delta strain帖子里的表现一模一样哎。
首先你这个"11个月"的claim就是错的，我稍微查了一下关于alpha variant的文献 (不巧，就在几个楼层前这位作者的twitter还被你用来"证明"delta variant是从加州被带印度或者比印度变种更早。我在"证明”一词上挂上双引号，是因为他的twitter内容还跟你的claim相反)
https://virological.org/t/preliminary-genomic-characterisation-of-an-emergent-sars-cov-2-lineage-in-the-uk-defined-by-a-novel-set-of-spike-mutations/563
文章写到： The two earliest sampled genomes that belong to the B.1.1.7 lineage were collected on 20-Sept-2020 in Kent and another on 21-Sept-2020 from Greater London.
也就是说alpha variant最早被察觉是在去年9月份，而不是你说的11个月都没有任何变种。我猜能被RNA sequencing察觉前应该也传播了半个，一个月吧？那时候有什么疫苗呢？ 其次他在推测这个变种可能的来源时引用了一些之前的研究，发现很多变种的出现是在有免疫缺陷的病人被新冠长期感染，并接受新冠治疗例如 convalescent plasma 后。
那他们为什么会被新冠感染呢？难道不是因为当时没有什么有效控制新冠在社区传染的手段，比如管用的疫苗或者严苛的lockdown吗？

你这么强烈反疫苗，没关系，那么拜托拜托，请花同等时间推广你所谓的物理隔离吧！更不要淡化社区传播的可怕！
ok
那还是8个月没有一个变种出现 然后10个月一下来了那么多变种
mutation rate为何发生了这么大的变化？

Health experts urge caution on giving Covid vaccines to UK children As the US and Europe approve plans to immunise teenagers, scientists in Britain advise delay https://www.theguardian.com/society/2021/may/29/health-experts-urge-caution-on-giving-covid-vaccines-to-uk-children

who的话谁爱信谁信
添堵。。。。。
全世界绝大部分人信， WHO制定的疫苗等等规则，基本上全世界国家会遵照执行。
这些不是以你个人意愿为转移的。
可是现在溯源不又成为主流了？
那到底应该信谁的啊？？
我家男孩早打完了第一针，第二针本来还在犹豫要不要打，现在被以色列的新增case吓了一跳，看来60%的人口疫苗普及率挡不住delta变种，决定去给他打第二针
疫苗只防重症和死亡，不防传播，成人打不打和娃有什么关系？
溯源和叫Chinese virus是一回事吗？
蠢货！
18
疫苗挡不住delta变种为什么要打啊？
谁说疫苗不防传播。不防传播还要什么70%goal?
就怕学校要求，或者哪怕只是宣传，会照成peer pressure
疫苗接种率不够，所以病毒会接着传播。打了后至少可以保证他被传染了不会去住院或重症啊。
防传播的话为什么这么多breakthrough case? 成人打了两针后再测试出positive就不传染你娃了？
要是真的不防传播的话breakthrough case比现在多多了，会像全体接种科兴疫苗的美洲杯一样。
这个也是张口就说
多多了？你知道现在确切有多少breakthrough case? 只怕是现在breakthrough case太多，CDC现在都懒得跟踪了，只看重症和死亡
这个话却不能说。说了就挨骂。
按照同样的逻辑，新冠疫苗其实也不能防重症和死亡，以色列的辉瑞数据摆在那里呢，打完疫苗一样也有重症死亡的。
话说反疫苗可以，但是别拿这种小学生都不会犯的错误来说事儿呀。
https://www.who.int/zh/news/item/01-06-2021-who-validates-sinovac-covid-19-vaccine-for-emergency-use-and-issues-interim-policy-recommendations
"由于参加临床试验的60岁以上老年人极少，因此无法估计对该年龄组的效力。尽管如此，世卫组织并不建议对该疫苗设置年龄上限，因为随后在多个国家使用期间收集的数据和免疫原性辅助数据表明，疫苗对老年人可能也有保护作用。没有理由认为疫苗的安全性在老年人和年轻人群中会有不同。"
另外,我对儿童打疫苗没有观点, 只是对世卫的行为比较看不懂
是不是防重症和死亡大家一起看啊，现在这个说法难道不是媒体以及一些专家说的？最开始一直宣传疫苗防止病毒传播，更防止重症和死亡吧？现在已经改口说疫苗不防止传播，只防止重症和死亡。小土豆公开讲话难道是故意骗人的？过一段时间是不是又要改口疫苗既不防传播也不防重症和死亡了？谁反疫苗啊？从小到大正式批准的疫苗不知道打了多少剂了，对这个还没ready的疫苗谨慎就是反疫苗？我看你才是小学生吧，恐怕只有小学生才会不停的无脑跟风被忽悠，被忽悠完了只能当鸵鸟，不看不听就地打滚就可以觉得疫苗是仙丹，百利无害
Beyond their substantial protection of individual vaccinees, coronavirus disease 2019 (COVID-19) vaccines might reduce viral load in breakthrough infection and thereby further suppress onward transmission.https://www.nature.com/articles/s41591-021-01316-7
溯源和喊Chinese virus有什么联系么？
More evidence is needed on the use of the different COVID-19 vaccines in children to be able to make general recommendations on vaccinating children against COVID-19.
WHO's Strategic Advisory Group of Experts (SAGE) has concluded that the Pfizer/BionTech vaccine is suitable for use by people aged 12 years and above. (这段话是说不建议给儿童打吗？还是我理解错了？诚心请教）Children aged between 12 and 15 who are at high risk may be offered this vaccine alongside other priority groups for vaccination. Vaccine trials for children are ongoing and WHO will update its recommendations when the evidence or epidemiological situation warrants a change in policy.
It's important for children to continue to have the recommended childhood vaccines.
why do you cherry-picking sentence? ! the below is the full statement of WHO, which didn''t change a WORD from june 3rd, 2021!!!!
WHO SHOULD GET VACCINATED The COVID-19 vaccines are safe for most people 18 years and older, including those with pre-existing conditions of any kind, including auto-immune disorders. These conditions include: hypertension, diabetes, asthma, pulmonary, liver and kidney disease, as well as chronic infections that are stable and controlled. If supplies are limited in your area, discuss your situation with your care provider if you: Have a compromised immune system Are pregnant (if you are already breastfeeding, you should continue after vaccination) Have a history of severe allergies, particularly to a vaccine (or any of the ingredients in the vaccine) Are severely frail Children should not be vaccinated for the moment. Children and adolescents tend to have milder disease compared to adults, so unless they are part of a group at higher risk of severe COVID-19, it is less urgent to vaccinate them than older people, those with chronic health conditions and health workers.

这段话我的理解是高风险的孩子还是要打，低风险的孩子应该把疫苗留给高风险优先人群，你细品一下。
据主流媒体说
因为trump喊了 所以为了不要搞政治迫害 去年就大力打压溯源的呼声
题文不符啊。最后一句不是“建议儿童打儿童疫苗”吗？
那这就not applicable to the U.S.了，因为美国并不缺疫苗。
那这贴标题就是故意带风向啊，如果没点开原文，我以为因为疫苗副作用不建议儿童打
我理解，早上还没有pfizer那段话，就是疫苗不够的国家，儿童不用打（除了美国也没得打。。。）
是的，就是说疫苗不足，儿童衡量没必要作为priority group打。个人按照当地情况决定吧，谁也没办法替谁做决定。
那我们来算算？国内的宣传稿说科兴给美洲杯捐了50000剂疫苗保障比赛顺利进行，这些疫苗最多能打25000人，实际上应该还没这么多。然后开赛这才几天已经140多新增了，光上个周末就多了接近60个，我们就算每万人每天10个吧，很保守很保守的估计。然后前面有人说麻省，他们有400多万fully vaccinated，按美洲杯这个速度的话一天就能有4000个breakthrough，比他们从一月份到现在积累的breakthrough case总量还多。。。
除 covid 以外的常规疫苗。
完全没看明白 为啥凡事都要提墙内疫苗
就是priority低，所以我说是不是跟去年的口罩一个意思。😄
你得到了它！
就是的啊，吵什么 china virus, trump, 科兴啊，跟我们有什么关系啊。娃要不要打疫苗，才是切身利益啊。
我读了整篇文章。没有感觉到是因为疫苗不够的意思。
哦 我提trump的意思仅仅是 坏蛋也可能偶尔说一句实话的
不能完全因为坏蛋也说了 就怀疑一件事的正确性
按你家当地打疫苗的情况和感染数字决定吧，有concern就不打。WHO是World organization，美国发达地区疫苗泛滥和非洲地区缺医少药的儿童用一个recommendation的。
你是对的。
看了半天，就这一个正经点的回帖
儿童的身体器官，免疫系统跟成人有区别，直接跟成人一样打，听着就有点瞎来
儿童自己没啥能力选择，做父母的自己还是要把好关
靠谱
真的是，自己不打也就算了，还鼓动呼吁别人不要打，这是什么心理？
我们 local 大群里面一个疯婆子就这样。狂热川粉，真是令人讨厌。
between the lines
脑子是个好东西，防止传播也不是100%了解一下
又读了好几遍。感觉是有你说的意思。
脑子也的确是个好东西，整天看着媒体和所谓的专家一天变个说法，政客利诱恐吓达到目的，有些人自己无怨无悔的跟风也就罢了，没人说你们愿意跟风的如何如何，倒是这些自己跟风的还跑来诅咒辱骂不愿意无脑跟风的人，倒底谁没脑自己看
我不知道你看的啥媒体和专家说法，辉瑞和moderna的数字去年就挂在网上了，95%和94%efficacy，谁也没说这疫苗百分之百地防病毒防传染呀。为啥有个breakthrough就闹得跟发现了什么惊天秘密似的，拿5%的人群不当人群咩。
95%不等于零，不是百分之百的保护率不等于没用，这个道理真的是小学生都会明白的。我没说你是小学生啊，我只是说连小学生都知道的道理，怎么有些人就是不明白呢。
光是防重症而不阻断传染的话 就不要继续道德绑架别人打疫苗了吧
本来这个疫苗就是很新的事物，每个人都有权利作出自己的判断和选择，没必要因为选择不同而指责甚至歧视他人。
关于疫苗能否阻断传染，请问有数据吗？
你这种全家都得过covid的就别来蒙这些没得过的人了，说多了只会让人怀疑你动机不良。。。。
说说有啥动机不良？
阻断的话 不就是应该测无症状的人数吗？
可是人家trial的时候根本就没想过测这个
这句话我早上看的时候好像没有啊？？？？既然 suitable, 为啥又不建议打？？？？
对，早上没有，后来加的。谁知道明天又说什么。不用当真了，根据自己和local的情况定吧。
这变动的也太飞速了
因为这是一个政治正确挂帅的时代，讲科学首先要讲政治正确

打了疫苗的人的传播率比不打疫苗的低得多啊https://www.nature.com/articles/s41591-021-01316-7。要说不能阻断传播，还不是那些不打疫苗的人贡献大得多。还好意思说打了疫苗的人没帮你们阻断传播。然后不打疫苗感染了得重症又高得多还去占用医疗资源。现在得了新冠住院的95%以上是没打疫苗的。本来打不打你自己选择，硬要跳起指责打了疫苗还不帮你阻断传播就是太不要脸了。
你以全家得covid的代价已经证明了光自己戴口罩是防不住感染的。然后你在这里告诉大家戴口罩比打疫苗有效。。。。
别人有资格这么说，你肯定没资格说。。。。
这个得过covid却这么反疫苗得不会是觉得自己得了亏了，希望别人不打疫苗也得。否则真的很难理解。
WHO 这个说法从减轻传染病后果角度来讲是对的，当然各国自然是以自己为重，不会听who的
传播链条是因为大人不打，儿童为什么要为成人做出牺牲？
不要忘了现在疫苗还是EUA
你怎么知道她不是 得过了很轻松地康复了，觉得没什么大不了，得新冠都比打疫苗好？ 本来人人都是基于自己的经历和信息，宣传自己相信的东西，没毛病
你quote的那位补脑过度 我都不知道解释了多少回了 我让小孩戴口罩去学校 老师表示这属于防范过度
实在不知道说神马好了
我好好的在家里 偶尔去放个风也额外小心 居然也有人觉得我会对养蛊做巨大的贡献 好吧 那就只好贡献了
有点没看懂逻辑，既然按你说的60%的疫苗普及率挡不住delta变种，那疫苗对Delta变种到底有效果吗？
