(早报讯)一项研究指出,施打辉瑞疫苗会略增心脏发炎风险,但染疫者心肌炎风险更高。
路透社报道,《新英格兰医学杂志》周三(8月25日)发表的研究报告指出,据最大医疗服务机构Clalit的数据,以色列每10万名接种辉瑞疫苗的患者中,有1到5名可能会罹患原本不会得到的心肌炎,而这个比例在感染冠病患者之中更高;每10万名确诊患者中,有11人会罹患心肌炎。
研究员对比了超过88万名接种者和相同数量的未接种者中,出现不良反应的几率。总体而言,接种疫苗的组别中,有21人罹患心肌炎,其中主要为年轻男性;而未接种组别中则有6人罹患心肌炎。
研究员说,接种者在接种疫苗后出现的不良反应大多轻微,但有些严重不良反应例如心肌炎。
研究员还分析了超过24万名冠病患者出现不良反应的几率。结果表明,感染冠病本身是罹患心肌炎的高风险因素,并也增加了出现其他不良反应的风险。
新加坡研究:疫苗对抗Delta变异株 保护力达69%

7/07/2021
新加坡今天表示,当地一项研究显示,接种疫苗对防止感染Delta变异株的保护力为69%,对预防重症的效力高达93%;当局说,目前缺乏中国科兴疫苗对抗Delta变异株性能的数据。
卫生部长王乙康今天在在线记者会表示,新加坡国家传染病中心与卫生部合作,过去几个月对1000名2019冠状病毒疾病(COVID-19)确诊者的家庭密切接触者进行研究。
他指出,研究结果发现,接种疫苗对防止感染最早出现于印度的Delta变异株的保护力为69%,这与国际上的数据一致。新加坡研究数据显示,接种疫苗防止出现症状的效力为80%至90%,预防重症出现的效力高达93%。
新加坡去年底启动全国COVID-19疫苗接种计划,目前批准使用辉瑞/复必泰(Pfizer-BioNTech/Comirnaty )、莫德纳(Moderna)等2款mRNA疫苗。星国也采购中国科兴(Sinovac)疫苗,目前尚未批准使用,也未列入全国疫苗接种计划。
虽然新加坡卫生科学局尚未批准使用科兴疫苗,但首批疫苗2月底就运抵。星国当局日前开放私人医疗业者申请使用现有的20万剂科兴疫苗,为希望接种的民众施打;自6月中开打以来,吸引不少旅星的中国籍民众前往接种。
媒体问及,已接种科兴者之后可否改选接种全国接种计划使用的疫苗,新加坡卫生部医药服务总监麦锡威(Kenneth Mak)表示,有些人可能在新加坡接种一剂或2剂科兴疫苗,或有些人在外国接种一剂其他款疫苗后回到新加坡,他们仍可在全国疫苗接种计划下,接种辉瑞或莫德纳疫苗。
他强调,虽然理论上接种两种不同疫苗的效果是好的,但目前缺乏足够实际证据证明这点,当局会告知民众这点,让他们做出选择。
至于为何接种科兴疫苗者未列入新加坡全国接种人口数据中,麦锡威回应表示,政府有追踪当地接种科兴疫苗的人数,等时机合适,当局可能会提供接种科兴疫苗的人数。
他指出,目前有关科兴疫苗性能的数据不足,特别是有关对抗Delta变异株的数据不如信使核糖核酸(mRNA)疫苗多。目前有足够证据显示,接种mRNA疫苗者能获得很好的保护,因此有关接种进度统计,当局只计算接种mRNA疫苗的人数。
王乙康补充,目前尚未有医学或科学基础证明科兴疫苗在预防感染Delta变异株和避免重病的性能。不过,随着当地越来越多人接种疫苗,群体免疫也会更强,到时候,政府应该可以扩大放宽限制,让只接种一剂或尚未接种疫苗者也能参与大型活动。
此外,卫生部日前接获通报,一名16岁青少年接种一剂辉瑞疫苗后第6天在健身房举重,不久后在家昏倒,经送医急救,初步诊断为心脏骤停。麦锡威表示,目前正在调查原因,包括是否因接种疫苗引起,或与少年服用的保健品有关。
他说,这名青少年举重当时使用的重量是自身体重的一倍,是非常剧烈的运动。

(早报讯)一名16岁少年在接种首剂辉瑞冠病疫苗的六天后,于健身房举重不久后心脏骤停。卫生部与国大医院正在调查是否与急性严重心肌炎有关。
有鉴于此,冠病疫苗专家团建议所有公众,尤其是青少年和30岁以下的年轻男性,在接种冠病疫苗后的一个星期,避免剧烈的体力活动。
卫生部今天(7月5日)发文告说,当局是在7月3日接获通报,指一名16岁新加坡籍少年于当天上午在家中昏倒,被送往邱德拔医院急诊部,傍晚被转到国大医院的加护病房。
这名少年在6月27日接种首剂辉瑞/复必泰(Pfizer-BioNTech/Comirnaty)冠病疫苗,经医护人员评估为适合接种。他在注射疫苗后接受30分钟观察,情况良好,接种五天后仍无恙。
卫生部透露,他在7月3日昏倒之前,曾在健身房举重,训练时使用非常重的重量,超过自身的体重。
少年的病况初步诊断为心脏骤停(cardiac arrest)。卫生部正与国大医院的医疗团队合作,为少年进行临床测试,以确定是否与接种疫苗或急性严重心肌炎(acute severe myocarditis)有关。

FDA加注警语 辉瑞、莫德纳疫苗恐增心肌炎风险
中央社
6/26/2021
美国食品暨药物管理局今天对辉瑞大药厂和德国BioNTech共同研发的COVID-19疫苗,以及莫德纳疫苗,在注射后出现心脏发炎的罕见风险,加注警语。
美国食品暨药物管理局(FDA)表示,在提供给医护人员的疫苗数据单张做了若干修正加注警语,提醒接种后不良事件通报显示发生心肌炎和心包炎的风险增加,特别是在施打第二剂之后,以及疫苗施打几天后,出现的症状。
根据疫苗接种后不良事件通报系统(VAERS),截至6月11日,全美已施打3亿剂莫德纳(Moderna)与辉瑞(Pfizer)/BioNTech的两款mRNA疫苗中,有1200多起心肌炎或心包膜炎病例。
这些案例在男性身上、以及打完第2剂一周内发生的情况特别高些。根据美国疾病管制暨预防中心(CDC),有309名30岁以下年轻人住院,其中295人已经出院。
有几个国家卫生监管单位已经在调查,注射莫德纳和辉瑞的两款mRNA疫苗后发生心肌炎和心包炎的病例,这些在年轻男性身上发生的频率较高。
疾管中心预防接种咨询委员会(Advisory Committee on Immunization Practices, ACIP)于23日召开会议,广泛检讨关资讯之后,FDA作上述更新。
辉瑞和莫德纳公司在下班时间,并未立即回复路透的询问。

(早报讯)美国少数年轻人或青少年在接种冠病疫苗后出现心肌炎问题,美国疾病控制与预防中心(CDC)正就此展开调查,目前并未发现两者之间存在明确关联。
法新社报道,美国疾控中心指出,目前关于年轻人接种辉瑞-BioNTech或莫德纳等采用信使核糖核酸(mRNA)技术的冠病疫苗后出现心肌炎的报告“相对较少”,而且多数的症状轻微,可能同接种冠病疫苗无关。
据知,出现此情况的接种者主要是年轻人或青少年,他们在接种第二剂辉瑞-BioNTech疫苗或莫德纳疫苗的四天后出现症状,而出现症状的男性比女性多。
疾控中心补充说,在它的安全监控系统中,接种冠病疫苗后出现心肌炎的报告率与预期的基线率没有差异。
疾控中心没有发布出现心肌炎的人数或具体年龄的详细信息。
美国从5月中旬开始允许12至15岁的青少年接种辉瑞-BioNTech冠病疫苗。
研究:感染冠病后至少八个月仍有抗体

(早报讯)意大利研究员周二(5月11日)说,冠病患者在染病后,血液中至少八个月仍有抗体。
意大利米兰圣拉斐尔医院的一份声明说,“无论疾病的严重程度、患者年龄或其他疾病的存在”,患者仍有冠病抗体。
研究员和意大利国家卫生研究所(ISS)针对162名出现症状的冠病患者进行研究,这些患者在意大利去年的第一波疫情期间到急诊室接受治疗。其中三分之二的患者为男性,平均年龄为63岁;57%的患者有既往疾病,尤其是高血压和糖尿病。
研究员分别在3月和4月采集了血液样本,并在11月再次采集了幸存者的血液样本;此研究其中约29名患者已去世。
圣拉斐尔医院与意大利国家卫生研究所联合发表声明说:“中和抗体的存在虽然随着时间的推移而减少,但非常持久——诊断后八个月,只有三名患者的检测不再呈阳性。”
这项研究成果已发表于国际科学期刊《自然通讯》(Nature Communications)。此研究还强调了抗体产生在从冠病中恢复的重要性。研究员说:“那些无法在患病前15天内产生抗体的人,患上严重形式的冠病的风险更大。”
少数人接种辉瑞疫苗后出现心肌炎 以色列调查

(早报讯)以色列小部分人在接种辉瑞-BioNTech冠病疫苗后出现心肌炎的症状。以色列卫生部正在就此情况进行调查。目前尚未得出任何结论。
路透社报道,以色列冠病应对协调员阿什星期天(25日)表示,一项初步研究显示,在超过500万名接种辉瑞-BioNTech疫苗者中出现了数十起心肌炎个案。
这种情况大部分是在接种第二剂疫苗后出现,而且多出现在30岁以下的年轻人身上。
他说,以色列卫生部正在研究心肌炎的发病率是否过高,以及它是否可以归因于疫苗。
辉瑞表示对有关问题知情,并强调,该公司定期和彻底审查所有不良情况个案,并没有观察到心肌炎的发病率高于一般人口中可预见的发病率。
以色列已有500多万人接种了辉瑞-BioNTech冠病疫苗。

(早报讯)发表于《柳叶刀》医学杂志一项研究显示,民众在接种第一剂辉瑞冠病疫苗后两到四个星期内,对冠病病毒感染的有效性达85%。
法新社报道,这是针对以色列特拉维夫附近Sheba医院9000多名医务人员所进行的调查。该医院于12月19日发起了大规模疫苗接种计划,该接种计划被认定为是目前世界上最快的。共约有7000医护人员接种了第一剂疫苗,其余则未接种。
以色列的研究发现,民众在注射第二剂疫苗后一周内,辉瑞疫苗的有效性高达95%。
Six Spaces Home Staging
在这组调查对象当中,研究人员对那些表现出症状,或与冠病患者接触过的人进行测试之后发现有170人被诊断出患有冠病。其中,有52%尚未接种疫苗。
比较两组,Sheba的研究计算出该疫苗在接种后1到14天之间有效率为47%,在15到28天后有效率为85%。
该研究其中一名作者雷杰夫-约谢说:“我们看到的是,民众在接种疫苗后两周到四周之间就已经表现出非常有效的功效,可将冠病症状与其感染减少了85%。”
他说,尽管这种疫苗“非常有效”,但科学家仍在研究完全接种疫苗的人是否仍可以将病毒传播给他人。
马克龙感染冠病 多名政要受波及得自我隔离

(柏林综合电)法国总统马克龙冠病检测呈阳性,多名曾与他密切接触的法国和外国政要随后开始自我隔离。
爱丽舍宫昨天发布声明说,马克龙是因为出现初步冠病症状而接受检测。按照国家防疫规定,马克龙将“自我隔离七天,他将继续工作,并远程开展活动”。
马克龙是继美国总统特朗普和英国首相约翰逊之后,感染冠病的全球数位国家首脑之一。
与马克龙接触过的法国总理卡斯泰和国民议会议长费朗随即进入自我隔离。
欧盟多国誓要在年底前接种
马克龙周一在巴黎出席经济合作与发展组织主办的会议,同时与会的欧洲理事会主席米歇尔和西班牙首相桑切斯也自我隔离。
法国与其他欧盟成员国如今把抗疫希望寄托在冠病疫苗,纷纷誓言要在年底之前启动冠病疫苗接种。
德国卫生部长施潘宣布,德国将在12月27日开始分发由辉瑞和BioNTech公司联合开发的冠病疫苗,并优先考虑为居住在养老院的老年人接种。
欧盟成员国须等待欧洲药品管理局批准辉瑞疫苗的使用,才能开始接种计划。该疫苗已在英国、美国、加拿大等国家投入使用,预计欧洲药品管理局会在12月21日批准该疫苗。
施潘昨天说,如果如期获得批准,德国将在12月27日开始疫苗接种,欧盟其他成员国也计划在同一天启动疫苗接种。
德国每日新增确诊病例居高不下,周三新增死亡病例更是破最高纪录,达952起。德国全境从周三起实施“硬性封锁令”,直至明年1月10日。除了超市、药店和银行,所有非必需场所都必须关闭;学校和幼儿园也停课;企业员工则应暂停工作或尽量居家办公。
柏林市民坎布尔在防疫措施收紧的第一天,看着冷冷清清的街道说:“感觉像是星期天。这些措施是必要的,但也令人倍感压力。”
法国总理卡斯泰周三宣布,法国将于12月最后一周开启冠病疫苗第一阶段接种工作。法国年底之前会接收约116万剂疫苗,接下来两个月另有230万剂疫苗送达。
法国的冠病疫苗接种计划,未必获得人民的热烈响应。根据法国一项民调,仅53%受访者愿意接种疫苗,这个比率是全球最低之一。
欧盟委员会主席冯德莱恩周三在欧洲议会上说:“要结束这场大流行病,须要多达70%人口接种疫苗。这是一项艰巨任务,所以让我们尽快接种疫苗,27国从同一天开始。”
世界卫生组织欧洲支部呼吁欧洲人民在来临佳节期间须加强防疫,与亲友欢聚也要戴口罩及保持社交距离。世卫也警告,明年初欧洲可能暴发第三波疫情。

America has a super-spreader president. He put us all – and himself – at risk
BY Moira Donegan
Now that the virus has reached Republicans, maybe they will have to know what the rest of the world feels like?
Maybe Donald Trump got Covid-19 at the Rose Garden ceremony announcing his nomination of Amy Coney Barret to the supreme court. On Saturday, 26 September, Donald Trump gathered major Republican party leaders at the White House to celebrate his nomination of the rabidly anti-choice judge, along with national leaders in the anti-choice movement. At the event, onlookers were seated uncomfortably close together, and virtually none of them are wore masks. Barrett and her pointedly large family huddled around Trump both indoors and outdoors, without a thought of social distancing. Later, videos emerged from the event of Republicans hugging. In one, the attorney general, William Barr, wipes snot from his nose on to his hand, and then goes on to shake hands with many others – a metaphor for his time at the justice department that is perhaps a bit too on the nose. As numerous national Republicans sicken, at least eight cases of the virus have now been linked to that event.Trump, Covid and empathy for the world’s least empathetic manRobert ReichRead more
Or maybe Trump got it the night before, on Friday, 25 September, when he mingled, again unmasked and indoors, at a campaign fundraiser at the Trump International hotel in Washington. He rubbed elbows there with members of the Republican National Committee, including Ronna McDaniel, the committee chairwoman. McDaniel flew home to Michigan the next day, and began exhibiting symptoms of the virus a few days after. She has since tested positive.
Or maybe he got it at the presidential debate in Cleveland the following Tuesday, 29 September. Trump and his entourage were supposed to be tested upon their arrival at the venue, as the Biden camp was. Instead, the Republicans showed up late, and refused both testing and masks. Trump proceeded to scream, unmasked and nearly uninterrupted, for 90 minutes. Viewers watching on high-definition screens could see droplets of spittle flinging from his mouth. Among other things, at the debate he disparaged his opponent, Joe Biden, for wearing masks in public. Eleven cases have now been traced to that event.
It’s not clear when Trump last tested negative for the virus, and the White House has been elusive at best and deceptive at worst in their public accounts of when the administration became aware that the virus was circulating in the president’s inner circle and just how bad his condition has gotten. This past Friday, 2 October, Trump was airlifted to the hospital – but not until after financial markets had closed for the weekend. When a team of doctors gave a rosy depiction of his condition to assembled news cameras on Saturday, saying his prognosis was good, his chief of staff promptly contradicted them in an attempted off-the-record conversation with pool reporters, in which he said that the president was doing much worse than the doctors had made it seem.
The administration’s handling of the president’s illness has had the shambolic quality of Wile E Coyote attempting to catch Road Runner. They are caught in such absurdly transparent lies that one almost expects their noses to grow long as they speak, or a cartoon anvil to drop on their heads in divine retribution. It would be funny, if only these people did not also possess such terrifying power along with their ostentatious incompetence.
But even the Trump camp have not been able to deny that the president knew he had been exposed by Thursday, when Hope Hicks, the senior White House aide to whom the president is usually in breathingly close proximity, tested positive for the virus. Hicks had begun feeling ill while traveling with Trump on Wednesday night, but accompanied him on flights both before and after the onset of her symptoms. Despite Hicks’ positive test, Trump departed on Thursday for a campaign fundraiser at his golf club in Bedminster, New Jersey, where he schmoozed with guests both indoors and outdoors, did not wear a mask and welcomed donors to a buffet dinner.
Why would Trump endanger his own supporters like that? It has long been clear, both from their own statements and from reporting done by outlets such as Vanity Fair, that the Trump administration considers deaths and illness from the virus in blue states to be insignificant, acceptable casualties. But the choice in Bedminster to endanger his own supporters defies that logic. Unless of course, you are Donald Trump, who views ever interaction as transactional and every human being as a number. The Bedminster event, remember, was a campaign fundraiser – it ultimately raised more than $5m for his re-election bid. To Trump, even those who fulfill his own need for constant adulation are less valuable as human beings than they are as sources of revenue. And Trump certainly does not care about the workers whose labor is necessary to put on such events – the security and janitors and caterers and tech staff whose health, lives and families are threatened by his carelessness. The reason Trump continued on to the Bedminster fundraiser even after knowing he had been exposed is simple: he cares less about even his supporters’ safety than he does about getting their money.
There is something poetic, even perversely satisfying, about seeing Trump’s delusions about his own power and imperviousness defied by his infection. Here is a man who has wielded money, privilege and deception to evade consequence in every manmade system. He is not capable of being shamed, and he is seemingly invulnerable to the law, with prosecution of his crimes suspended until he leaves office and civil lawsuits impacting him with all the effectiveness of spitballs launched at a tank. Bad things don’t usually happen to Donald Trump, no matter how much recklessness he exhibits or how much suffering he inflicts, because he is usually able to lie, buy or cheat his way out of his comeuppance. Not so with the virus, which has infected him even though he has treated the disease more as an inconvenient nuisance rather than a national emergency.
Donald the Super-Spreader is an insult to those Americans who have altered their own lives beyond recognition in order to fight the coronavirus
But more than anything, Donald the Super-Spreader is an insult to those Americans who have altered their own lives beyond recognition in order to fight the coronavirus. As lockdowns began in March, the Americans who retreated to their homes were told that the extreme measures were temporary ways to slow the speed of the disease and buy time for the government to come up with a viable response. But the Trump government did not respond, and instead our lives warped and narrowed. Millions have lost their jobs. Children’s educations have suffered as schools have been forced to close. Women who must supervise their children’s online learning have been forced from the workforce at a disproportionate rate, and many of those women’s careers will never recover, their dreams dashed permanently by the incompetence of the federal response. Meanwhile, many of us have not seen our parents in months, for fear of infecting them. More than 210,000 Americans have now died from the virus, most of them alone and all of them needlessly.
Meanwhile, nothing about national Republicans lives seem to have changed. They go on hugging and gathering in close together, wiping their noses on their hands and then shaking them, yelling wide-mouthed about the ineffectiveness of masks. Watching the videos of the Rose Garden ceremony, I couldn’t help but think of the funerals I have attended over the past year over Zoom. Trump and the national Republicans have been living in a different world from the rest of America. Now that the virus has reached them, maybe they will have to know what our world feels like.
