青少年的孩子接种COVID-19疫苗是否安全？

 

2. Is it safe for my adolescent or teen to get the COVID-19 vaccine?

 

 

The Pfizer COVID-19 mRNA vaccine is approved for those 12 years of age and older. Other COVID-19 vaccines are still being tested in those younger than 18 years of age.

When the Pfizer vaccine was tested in 12- to 18-year-olds, it was found to be safe:

  • Those 16- to 18-years old were included in the trials presented to the FDA in December 2020. Since then, more than 2 million teens had received one dose of the vaccine, and more than 1 million had received both doses by May 12, 2021 – the date that the vaccine was approved for 12- to 15-year-olds. 

  • The clinical trial in 12- to 15-year-olds evaluated about 1,100 children who received the vaccine and compared them with about the same number who got placebo (a salt solution) as well as almost 2,000 16- to 25-year-olds who were vaccinated and about the same number in an age-matched placebo group. No vaccinated individuals got infected with COVID-19 or experienced severe side effects, like anaphylactic allergic reaction. A small number experienced swelling under the arm on the side in which the vaccine was administered. Called lymphadenopathy, this can also occur in adults who get the mRNA vaccines. This side effect occurred 2-10 days after vaccination and typically lasted up to 10 days.  Trial participants will continue to be followed for up to two years.

  • As increasing numbers of teens have been vaccinated, a few cases of myocarditis have been identified. It appears that the rates are greater than would be expected, so additional efforts are being made to identify this condition following receipt of the mRNA vaccine. Recently vaccinated young adults should report chest pain or shortness of breath following receipt of the COVID-19 vaccine, so that they can receive appropriate care and cases are accurately reflected to determine if this is caused by receipt of the vaccine.

  1. 青少年的孩子接种COVID-19疫苗是否安全？

辉瑞/BioNTech（复星的复必泰也是同一个疫苗）的COVID-19 mRNA疫苗已被批准用于12岁及以上人群（这里指美国，不同地区批准情况不同）。其他COVID-19疫苗仍在18岁以下人群中进行测试。

辉瑞公司的疫苗在12至18岁的人身上进行测试时，证实疫苗在这个年龄段中是安全的:


  1. 在2020年12月提交给FDA的试验中也纳入了那些年龄段在16至18岁的人。从那时起截止到2021年5月12日-该疫疫苗被批准可用于12至15岁的人的日期，已有超过200万青少年接种了一剂疫苗，超过100万青少年已接种了两剂疫苗。


  1. 12至15岁儿童的临床试验评估了约1100名接种疫苗的儿童，并与大约1100名接種安慰剂（生理盐水）的兒童比較.另外也將近2000名16至25岁的接種疫苗者和大约相同数量的同年龄群的安慰剂组进行了比较。接种疫苗者中沒有感染COVID-19的或出现严重的副作用，如过敏性休克反應。少数人在注射疫苗的該侧手臂下面出现了淋巴结肿大引起的肿胀，这情形也可能发生在接种mRNA疫苗的成年人身上。这种副作用发生在疫苗接种后的2-10天，通常持续不超过10天。 试验参与者将继续接受长达两年的随访。

  2. 随着越来越多的青少年接种疫苗，一些心肌炎的案例已被通報。目前發生的比率看起來比背景值要高，因此相關單位正在进行额外的努力，以确定接受mRNA疫苗后的這種情况。最近接种COVID-19疫苗的青少年应在接种疫苗后通報胸痛或呼吸急促的症狀，以便他们能够接受适当的醫療照顧，并幫助相關單位准确統計病例，以确定这些症狀是否是由接种疫苗引起。
