美国新冠病毒疫苗可能引起皮肤反应 但并不危险

  新冠病毒仍是困扰所有人的最大问题,那么新冠疫苗的情况你是否了解?一起和天道小编了解一下接种新冠疫苗的情况吧。

  新冠病毒脚趾、现代手臂、全身皮疹:研究表明,新冠疫苗可以引起皮肤反应,但并不危险

  伊丽莎白·怀斯《今日美国》

  感染COVID-19会导致各种奇怪的皮肤反应。一项新的研究发现,包括COVID - toes(一种类似麻疹的皮疹和带状疱疹)在内的一些症状也可能很罕见,幸好是使用辉瑞生物技术或Moderna疫苗的副作用很短暂。

  在414例与疫苗有关的延迟性皮肤问题的数据库中,我们看到了轻微的过敏反应,尽管有时会让人发痒和讨厌,但这些反应已经报告给了卫生保健专业人员。这些病例是在去年12月至今年2月期间收集的,当时强生公司的疫苗尚未获得批准,因此不包括在内。

  研究报告的主要作者埃斯特·弗里曼博士认为,这一发现让人安心。

  麻省总医院全球健康皮肤病学主任Freeman说:“人们可能会全身起疹子,这可能令人吃惊,也有点可怕,但这些患者做得非常好,恢复了,能够再回去接受第二次注射。”

  乔·拜登(Joe Biden)承诺,到4月19日,所有成年人都有资格接种新冠疫苗:但预约时间如何?

  她说:“接种新冠疫苗后4小时或更长时间开始出现皮疹的人,0%会出现过敏反应或其他严重反应。”“零是个不错的数字。”

  研究中描述的延迟皮肤反应通常在接种疫苗后一天左右开始,但可能会在7至8天后出现。它们不同于严重的、立即的过敏反应,后者发生在接种疫苗的前四小时内。

  研究结果发表在周三的《美国皮肤病学会杂志》上。因为这些病例只包括那些报告给皮肤科登记的人,所以很难说他们在所有接种疫苗的人中有多普遍。总的来说,研究人员认为,由于在患者中看到的数量很少,这种情况很少见。

  虽然对疫苗的皮肤反应可能会发生,但只要在接种后4小时以上就会发生,一般不会危及生命。

  “人们可以放心地接种第二针疫苗,”弗里曼说,他是国际COVID-19皮肤病学登记处的首席研究员。“即使你在接种疫苗后出现了相当严重的皮疹,只要它不是在接种后4小时内开始的,你应该感到很舒服的第二次接种。”

  研究人员指出,大多数接种疫苗的人不会产生任何反应。Moderna和辉瑞生物技术公司的临床试验报告了罕见的皮肤反应,最近一项对近65000人的研究发现,接种疫苗后的过敏反应是极为罕见的事件。

  弗里曼说,任何经历严重症状的人都应该咨询医疗专业人员。

  对第一剂疫苗有皮肤反应并不意味着你会有一到第二剂疫苗。在第一剂疫苗接种后出现皮疹的患者中,不到一半(43%)的人在第二剂疫苗接种后又出现皮疹。

  最常见的反应是在注射部位出现红色皮疹,有时甚至是发痒,这种情况可能发生在接种后一周左右。它被称为新冠病毒臂或现代病毒臂,因为大约95%的反应发生在现代病毒疫苗。

  对于Moderna arm,大多数人在第二次注射时都没有复发。在这些人当中,这种症状通常不那么明显,平均在三到四天内就会消失。

  COVID - toe是另一种罕见、恼人但不危及生命的反应。也被称为pernio或冻疮,皮肤溃疡或肿块发生在病人的脚趾上,约10%的病例发生在手指上。它们会导致手指出现红色或紫色的肿胀,并可能与血管壁的炎症有关。

  “你的脚趾变成紫色是不舒服的,但这不是不接受第二次注射的理由,”弗里曼说。

  一些患者报告的全身皮疹,称为麻疹型皮疹,通常被称为“麻疹样”,尽管它不是麻疹。

  有一些报道称,儿童时期患水痘的人在接种疫苗后爆发了带状疱疹。

  另一种反应是用皮肤填充物进行美容治疗的人皮肤肿胀,虽然这种情况很罕见。

  “如果你做了面部填充物,并不意味着你不应该接种疫苗,”弗里曼说。

  在那些对辉瑞生物技术或现代疫苗有立即过敏反应的人中,这种情况极为罕见,没有死亡报告。

  一项针对马萨诸塞州总医院(Massachusetts General Hospital) 65,000名接种过辉瑞或Moderna疫苗的员工的研究发现,危及生命的过敏反应发生率为0.025%。

  那是1%的四十分之一。这是一个非常好的低数字。”

  COVID toes, Moderna arm, all-body rash: Vaccines can cause skin reactions but aren't dangerous, study says

  Elizabeth Weise USA TODAY

  Getting COVID-19 can cause all manner of odd skin reactions. A new study finds some of them, including COVID toes, a measles-like rash and shingles also can be rare, and thankfully brief, side effects of getting the Pfizer-BioNTech or Moderna vaccines.

  The minor, though sometimes itchy and annoying, reactions were seen in a database of 414 cases of delayed skin problems linked to the vaccines and reported to health care professionals. The cases were collected between December and February before the Johnson & Johnson vaccine had been authorized, so it was not included.

  None caused a life-threatening reaction, a finding the study's senior author Dr. Esther Freeman found reassuring.

  “People can get full-body rashes, and that can be surprising and a little scary, but these patients did extremely well, recovered and were able to go back and get their second dose,” said Freeman, director of global health dermatology at Massachusetts General Hospital.

  Joe Biden has vowed vaccine eligibility for all adults by April 19:But what about appointment availability?

  “For people whose rashes started four or more hours after getting the vaccine, 0% of them went on to get anaphylaxis or any other serious reaction,” she said. "Zero is a nice number."

  The delayed skin responses described in the study often start a day or so after vaccination but can appear as long as seven to eight days later. They are different from severe and immediate allergic reactions, which occur within the first four hours of getting vaccinated.

  The findings appeared Wednesday in the Journal of the American Academy of Dermatology. Becausethe cases only include those reported to a dermatological registry, it’s impossible to say how common they across all people getting the vaccines. In general, the researchers believe them to be rare given the low numbers seen among patients.

  While skin reactions to the vaccines can occur, as long as they start more than four hours after vaccination, they are generally not life-threatening.

  "People can feel reassured about getting the second dose of their vaccine,” said Freeman, who is the principal investigator for the international COVID-19 Dermatology Registry. “Even if you have a pretty impressive rash after the vaccine, as long as it didn't start within four hours of vaccination you should feel comfortable getting the second dose."

  Researchers point out most people who get vaccinated do so without developing any sort of reaction. The Moderna and Pfizer-BioNTech clinical trials reported rare skin reactions and a recent study of almost 65,000 people found that anaphylaxis after vaccination was an extremely unusual event.

  Anyone experiencing severe symptoms should consult a health care professional, Freeman said.

  Having a skin response to the first dose of a vaccine doesn’t mean you will have one to the second dose. Fewer than half – 43% – of patients who got a rash in response to their first dose of vaccine had a rash after their second.

  The most commonly reported reaction was a raised, sometimes itchy red rash, often at the site of the injection, which can occur up to a week or so after being vaccinated. It’s been called COVID arm or Moderna arm, as about 95% of the reactions occur with the Moderna vaccine.

  For Moderna arm, most people had no reoccurrence when they got their second shot. Among those that did, it was generally less pronounced and faded on average within three to four days.

  COVID toes were another rare, annoying but not life-threatening reaction. Also called pernio or chilblains, the skin sores or bumps occur on a patient’s toes, and in about 10% of cases on the fingers. They can cause red or purple swelling of the digits and are likely linked to inflammation of the blood vessel walls.

  “Having your toes turn purple is uncomfortable but it’s not a reason to not get the second dose,” Freeman said.

  An all-body rash reported by some patients, called a morbilliform rash, often is referred to as “measles-like” though it isn’t measles.

  There were a few reports of people who had had chickenpox as children having a shingles outbreak in response to the vaccine.

  Another reaction was skin swelling in people who have had dermatologic fillers as a cosmetic treatment, though it was very rare.

  “If you’ve had facial filler, it doesn’t mean you shouldn’t get the vaccine,” Freeman said.

  Among those who had an immediate allergic reaction to the Pfizer-BioNTech or Moderna vaccines, it was extremely rare and no deaths have been reported.

  A study of 65,000 employees at Massachusetts General Hospital who were vaccinated with either the Pfizer or Moderna vaccine found the rate of life-threatening anaphylaxis was 0.025%.

  “That’s one-fortieth of 1%. That’s a really nice low number,” said Freeman.
