关于COVID-19疫苗的常见问题
- 谁目前有资格接种COVID-19疫苗?
Individuals 12 years and older are currently eligible to receive the two-dose Pfizer COVID-19 vaccine, while those 18 years and older can receive the two-dose Moderna or single-dose Janssen vaccine.
我们鼓励社区里的每个人都成为 #VaccineHero by getting vaccinated.
Pediatric patients ages 5-11 are now eligible to receive the two-dose Pfizer COVID-19 vaccine.
- 疫苗很快就生产出来了. How do I know it is safe?
The U.S. 疫苗安全系统确保所有疫苗尽可能安全. 在联邦合作伙伴努力制造COVID-19疫苗的同时,安全是首要任务. Despite what the name may suggest, “Operation Warp Speed” does not mean that manufacturers were able to skip steps or cut corners in the vaccine development process. Instead, after development of the vaccine, 制造商承担了一定的风险,并重复了研究, 制造和分销阶段. The FDA committed to giving these vaccinations priority (not rushed) review at all phases of the studies, 这有助于加快整个过程. Ongoing monitoring of vaccine effectiveness and side effect reports will continue to be evaluated by the FDA and the manufacturers.
- 如果我接种了COVID-19疫苗,我还应该戴口罩吗?
Yes. For several reasons, a mask and other proven methods of preventing COVID-19 (hand hygiene and social distancing) are still important even after receiving the vaccine. 接种疫苗后,身体通常需要几周的时间来建立免疫力. That means it is possible that a person could be infected with the virus that causes COVID-19 just before or just after vaccination. 这是因为疫苗没有足够的时间提供保护. Also, 而疫苗可以保护你不生病, 目前尚不清楚疫苗是否能防止感染病毒的人传播病毒.
In addition, 而COVID-19疫苗非常有效, there is a small percentage of people who might not be protected while the virus continues to spread – including those with compromised immune systems due to cancer and cancer treatments and those who are unable to be vaccinated due to severe allergic reactions to vaccine ingredients.
口罩还有助于预防新病毒, 疫苗的有效性尚不清楚. For these reasons, it is important to continue practicing safety measures like wearing masks until vaccines are widely administered and the virus is no longer spreading.
- 如果我已经感染了COVID-19并康复了, 当COVID-19疫苗可用时,我还应该接种吗?
Yes, at this time the vaccine is recommended even if you previously tested positive for COVID-19. Due to the severe health risks associated with COVID-19 and the fact that re-infection with COVID-19 is possible, individuals who have previously been infected with COVID-19 should proceed with getting the vaccine. However, 由于目前疫苗供应有限, you may be asked to wait to get the vaccine if you had COVID-19 within the previous 90 days, 因为在这段时间内再次感染的可能性很可能很低.
- 你会通过接种疫苗感染COVID-19吗?
No. The vaccine is NOT a live vaccine, 而且不可能因接种疫苗而感染COVID-19. 有些人会经历疫苗的副作用, such as headache, muscle pain, 或发烧,但这并不意味着你得了COVID-19. 这意味着你的身体正在努力建立对抗病毒的必要免疫力, which is a good thing.
- COVID-19疫苗可能产生哪些副作用/不良事件?
The most common adverse reactions reported have been fatigue, headache, fever/chills and joint pain. 这意味着你的身体正在努力建立对抗病毒的必要免疫力.
You can read more in Pfizer’s FDA Briefing Document and Moderna’s FDA Briefing Document 关于这些疫苗在疫苗研究参与者中报告的副作用.
- COVID-19疫苗可以接种给儿童吗?
目前不建议16岁以下儿童接种COVID-19疫苗.
- 孕妇可以接种COVID-19疫苗吗?
The American College of Obstetricians and Gynecologists (ACOG) recommends that COVID-19 vaccines should not be withheld from pregnant individuals. It is important to note that the COVID-19 vaccines currently available have not been tested in pregnant women, 所以没有关于孕期使用的安全数据. Pregnant women should make an informed decision after discussing with their healthcare provider.
- How many doses are required? 如果是多次,什么时候再注射一次?
全面疫苗接种的剂量方案将取决于你接种的疫苗类型. 辉瑞和Moderna的疫苗都需要注射两剂. 第二剂辉瑞疫苗应在第一剂后21天接种. The second dose of the Moderna vaccine should be administered 28 days after the first dose. 很重要的是要注意第二剂 must 与第一剂来自同一厂家.
其他类型的疫苗可能只需要一剂.
- What should I do if I am unable to get the second dose exactly 21 days (Pfizer) or 28 days (Moderna) after the first dose?
While it is recommended that you receive the second dose as soon as feasible after day 21 or day 28, 我们知道可能无法在预定日期收到. 这可能是由多种原因造成的. Please keep the following in mind if you cannot receive the second vaccine dose on the desired date:
- You must 接受与第一剂相同制造商的第二剂.
- 在理想日期过后,尽快接种第二剂疫苗, 因为晚注射第二剂总比不注射好. 从长远来看,你仍然会体验到同样的功效, although you may not see the full effect of the immunity until a few weeks after the second dose.
- 在接受我的全剂量方案后多久才被认为有效?
Similar to the flu vaccine, 接种疫苗后,身体通常需要几周的时间来建立免疫力. That means it’s possible a person could be infected with the virus that causes COVID-19 just before or just after vaccination and get sick. 这是因为疫苗没有足够的时间提供保护. As a general rule, 疫苗被认为是有效的大约两周后,你的全部剂量方案, according to the manufacturers. 如果你接种的是辉瑞或Moderna疫苗, which require two doses, 有证据表明,第一剂疫苗将开始提供一些免疫力, 但为了获得最佳效果,接受第二次注射仍然非常重要.
- Can I choose which vaccine I get?
我们不建议等待特定的制造商. All authorized COVID-19 vaccines have been proven effective in reducing the risk of becoming infected with the SARS-CoV-2 virus that causes COVID-19, decreasing the likelihood of having a severe case of the illness and reducing hospitalizations and deaths due to COVID-19 disease. 建议您接种可获得的第一种疫苗. 早防总比不防好.
- If receiving a two-dose regimen, should those who experience significant side effects from their first COVID-19 vaccine dose expect significant or worse side effects with the second dose? 那些之前呈covid -19阳性的人怎么办?
基于辉瑞和Moderna疫苗的数据, there appears to be an increased incidence of experiencing certain side effects from the second dose of the COVID-19 vaccine compared to the first dose (e.g.(发烧、疲劳、头痛、发冷、肌肉痛和关节痛). This does not mean that all vaccine recipients will experience these side effects with the first or second dose. A full list of the reported side effects comparing Dose 1 and Dose 2 may be found within the Pfizer BioNTech EUA Fact Sheet and the Moderna EUA Fact Sheet.
At this time, we do not have definitive data to state whether vaccine side effects are worse in patients who were previously positive for COVID-19.
- 接种疫苗后需要观察多长时间?
In general, a 30-minute observation period is recommended for anyone with a history of severe allergic reactions (due to any cause), 建议对所有其他个体进行15分钟的观察.
- COVID-19疫苗会导致COVID-19检测假阳性吗?
不,COVID-19疫苗接种不会导致COVID-19病毒检测假阳性. Per CDC guidance, the immunity response from a COVID-19 vaccine could possibly result in a positive antibody test, 哪些标志表明以前感染过病毒并有可能预防病毒.
- If I become COVID-19-positive following my first dose of the vaccine, should I take the second dose?
Per CDC guidance, 在症状消退后,您可以接种疫苗(任一剂量), if any, 并完成隔离期.
- COVID-19疫苗中包含哪些成分?
授权COVID-19疫苗的成分可通过CDC找到 link. Individuals with allergies to any of the vaccine components should discuss concerns with their healthcare provider before receiving the vaccine.
