疫苗预防coronavirus disease 2019 (COVID-19)也许是结束大流行的最佳希望。许多生物制药公司已申请美国食品和药物管理局(FDA)紧急使用新的Covid-19疫苗授权,并且在今年年底之前将有有限数量的疫苗。

It is likely that you have heard claims about the COVID-19 vaccine on social media or from people in your life. The quick development and approval of a vaccine may increase your hesitancy about its safety or effectiveness. Let's set the record straight on circulating myths about the COVID-19 vaccine.

Myth: The COVID-19 vaccine is not safe because it was rapidly developed and tested.


Mayo Clinic will recommend the use of those vaccines that we are confident are safe. While there are many COVID-19 vaccine candidates in development, early interim data are encouraging for the Pfizer vaccine which likely is to be the first authorized for emergency use by the FDA in the late December/early January timeframe. This vaccine was created using a novel technology based on the molecular structure of the virus. The novel methodology to develop a COVID-19 vaccine allows it to be free from materials of animal origin and synthesized by an efficient, cell-free process without preservatives. This vaccine developed by Pfizer/BioNTecH has been studied in approximately 43,000 people.


Myth: I already had COVID-19 and recovered, so I don't need to get a COVID-19 vaccine when it's available.

事实:There is not enough information currently available to say if or for how long after infection someone is protected from getting COVID-19 again. This is called natural immunity. Early evidence suggests natural immunity from COVID-19 may not last very long, but more studies are needed to better understand this. Mayo Clinic recommends getting the COVID-19 vaccine, even if you’ve had COVID-19 previously. However, those that had COVID-19 should delay vaccination until about 90 days from diagnosis. People should not get vaccinated if in quarantine after exposure or if they have COVID-19 symptoms.

Myth: There are severe side effects of the COVID-19 vaccines.

事实:There are short-term mild or moderate vaccine reactions that resolve without complication or injury. The early phase studies of the Pfizer vaccine show that it is safe. About 15% of people developed short lived symptoms at the site of the injection. 50% developed systemic reactions primarily headache, chills, fatigue or muscle pain or fever lasting for a day or two. Keep in mind that these side effects are indicators that your immune system is responding to the vaccine and are common when receiving vaccines.

Myth: I won't need to wear a mask after I get the COVID-19 vaccine.


Myth: More people will die as a result of a negative side effect to the COVID-19 vaccine than would actually die from the virus.

事实:社交媒体上流传声称有限公司VID-19's mortality rate is 1%-2% and that people should not be vaccinated against a virus with a high survival rate. However, a 1% mortality rate is 10 times more lethal than the seasonal flu. In addition, the mortality rate can vary widely and is influenced by age, sex and underlying health condition.



Myth: The COVID-19 vaccine was developed as a way to control the general population either through microchip tracking or nano transducers in our brains.

事实: There is no vaccine "microchip" and the vaccine will not track people or gather personal information into a database. This myth started after comments made by Bill Gates from The Gates Foundation about a digital certificate of vaccine records. The technology he was referencing is not a microchip, has not been implemented in any manner and is not tied to the development, testing or distribution of the COVID-19 vaccine.

Myth: The COVID-19 vaccine will alter my DNA.

事实:The firstCOVID-19到达市场的疫苗可能是信使RNA(mRNA)疫苗。根据CDC,mRNA疫苗通过指导身体中的细​​胞如何制备患有免疫反应的蛋白质。将mRNA注入您的身体不会与您的细胞的DNA相互作用或对任何事情进行互动或做任何事情。使用说明书后,人类细胞分解并尽快摆脱mRNA。


事实:Current mRNA COVID-19 vaccines were not created with and do not require the use of fetal cell cultures in the production process.
