TOKYO - Japan's health ministry has reported that there have been nine new incidents of women experiencing severe allergic reactions after receiving a coronavirus vaccine, local media reported Wednesday.
According to the health ministry and local accounts, medical facilities reported that female medical workers aged in their 20s to 50s experienced anaphylaxis after receiving the coronavirus vaccine developed by US pharmaceutical giant Pfizer and its German partner BioNTech SE.
The ministry here said the women who experienced anaphylaxis received the Pfizer jabs on Monday.
Despite displaying severe reactions, the ministry said they have all since recovered.
An investigation led by a panel of experts at the health ministry here has been charged with investigating whether the Pfizer jabs were responsible for sending the health workers into anaphylactic shock.
The ministry and local media reported that as of 5:00 pm on Tuesday, a total of 107,558 medical workers had been vaccinated, with anaphylaxis reported in 17 women.
Japan's public broadcaster NHK said the ratio of those going into anaphylactic shock after receiving the Pfizer jab was about one in 6,300 people, which equates to about 0.00015 percent.
Anaphylaxis is a potentially lethal and acute allergic reaction to an antigen to which the body has become hypersensitive.
The symptoms include, but are not limited to, coughing, wheezing, tightness in the chest, general pain, trouble breathing, rapid heartbeat, swollen or itchy throat, tightness in the throat, vomiting, diarrhea and a weak pulse.
When someone goes into a potentially life-threatening anaphylactic shock, which among the symptoms will almost certainly include their blood pressure suddenly dropping, a narrowing of their airways, and the blocking of normal breathing, they need immediate emergency medical attention.
If the reaction is not treated immediately, it can result in serious complications and can be fatal.
In addition, according to health experts, as many as one out of every five people may have a second anaphylactic reaction within 12 hours of the first. This is known as biphasic anaphylaxis.
2021年2月17日,日本东京东京医疗中心,一名医务人员在日本发起接种运动时,向注射器中注入一剂辉瑞-生物技术公司冠状病毒(新冠肺炎)疫苗。[图片/机构]东京——据当地媒体周三报道,日本厚生省报告称,已有9起女性在接受冠状病毒疫苗后出现严重过敏反应的新事件。据卫生部和当地报道,医疗机构报告称,20多岁至50多岁的女性医务人员在接受美国制药巨头辉瑞公司(Pfizer)及其德国合作伙伴生物技术公司(BioNTech SE)开发的冠状病毒疫苗后,出现了过敏反应。卫生部表示,经历过敏反应的妇女周一接受了辉瑞公司的注射。尽管表现出严重的反应,卫生部说他们都已经康复。由卫生部专家小组领导的一项调查负责调查辉瑞药厂是否是导致卫生工作者过敏性休克的原因。卫生部和当地媒体报道称,截至周二下午5点,共有107,558名医务人员接种了疫苗,据报道有17名女性出现过敏反应。日本公共广播公司NHK表示,接受辉瑞注射后过敏性休克的比例约为6300分之一,相当于约0.00015%。过敏反应是对身体变得高度敏感的抗原的潜在致命和急性过敏反应。症状包括但不限于咳嗽、喘息、胸闷、全身疼痛、呼吸困难、心跳加速、喉咙肿胀或发痒、喉咙发紧、呕吐、腹泻和脉搏微弱。当有人出现潜在的危及生命的过敏性休克时,其中几乎肯定包括血压突然下降、气道狭窄和正常呼吸受阻,他们需要立即进行紧急医疗护理。如果不立即治疗这种反应,可能会导致严重的并发症,甚至是致命的。此外,根据健康专家的说法,多达五分之一的人可能在第一次过敏反应后的12小时内出现第二次过敏反应。这就是所谓的双相过敏反应。
