Ryerson 大学教授回答疫苗相关问题

Question 1

“Some people are saying: whenever a vaccine is given, it will cause inflammation in our body, which might cause damage to the body is it true?”

问题1

有人说：每打一次疫苗就会引起身体一次炎症，这样会造成身体的损害。

Answer：

Let’s look at inflammation:  Some people who receive vaccination may notice a sore arm or feel something similar to influenza for a day or two. This is a form of mild local inflammation, and is soon forgotten. Other people have no response at all.

But 14 days after the second dose you are protected almost completely from serious illness, hospitalization, and death due to CoV-19.  Remember that in an UN-vaccinated person, the virus causes SERIOUS INFLAMMATION, first, in the lungs, and sometimes in kidneys, intestines, blood system, even the nervous system.  It is this inflammation that causes failure of various organ systems, and in some people, death.  The vaccines protect against that inflammation.  There is no comparison.

让我们来看看炎症：一些接种疫苗的人可能会注意到手臂酸痛或感觉类似于流感一两天。这是一种轻微的局部炎症，很快就会被遗忘。其他人根本没有反应。但是在第二次接种后 14 天，您几乎可以完全免于因 CoV-19 引起的严重疾病、住院和死亡。请记住，在未接种疫苗的人中，病毒会导致严重炎症，首先是肺部，有时是肾脏、肠道、血液系统，甚至神经系统。正是这种炎症导致各种器官系统衰竭，在某些人中导致死亡。疫苗可以防止这种炎症。没有可比性。

Question 2

“ people are saying: Covid vaccine will change your DNA, in the body is it true?”

问题2

有人说，疫苗会改变人的DNA

Answer:

“Not true. In fact it’s not even possible.  None of the vaccines contain DNA, and they do not enter or affect the nucleus of the cell (where your own DNA exists). The mRNA vaccine (Pfizer & Moderna) contain only “instructions” which stimulate the cell to produce some of the same protein that is on the outside of the virus. This helps the immune system recognize – and stop – the real virus when it appears.  No DNA involved.

The AstraZeneca vaccine is a harmless virus that contains some of the same virus protein – with the same result.  No DNA involvement there either.”

不对。事实上，这甚至是不可能的。没有一种疫苗含有 DNA，它们不会进入或影响细胞核（您自己的 DNA 存在的地方）。 mRNA 疫苗（Pfizer & Moderna）只包含“指令”，刺激细胞产生一些与病毒外部相同的蛋白质。这有助于免疫系统识别并阻止真正的病毒出现。不涉及DNA。 AstroZenica 疫苗是一种无害的病毒，它包含一些相同的病毒蛋白 – 具有相同的结果。那里也没有 DNA 参与。

Question 3

“People are saying Covid vaccines can cause your immune system overworking and cause other problems is it true?”

问题3

有人说疫苗会引起人类免疫系统过劳。

Answer:

“Not true. The immune system is able to respond to a wide range of different pathogens, and to create defenses against each one.  In the older times, before vaccines, children had to become actually ILL with the diseases (measles, mumps, whooping cough, diphtheria, etc. etc.) and they had to survive them.  If they survived, they were then protected by their stronger immune system.  The vaccines produce the same protection but WITHOUT the disease, disabilities, and death.  Sometimes we prefer not to give you a vaccination if you are already suffering from another illness, and wait until you recover before giving a vaccination.”

不對。免疫系統能夠對范圍廣泛的不同病原體做出反應，並對每種病原體產生防禦。在較早的時代，在疫苗出現之前，兒童實際上必須患上疾病（麻疹、腮腺炎、百日咳、白喉等），並且他們必須倖存下來。如果他們活了下來，他們就會受到更強大的免疫系統的保護。疫苗產生相同的保護，但沒有疾病、殘疾和死亡。有時，如果您已經患有另一種疾病，我們寧願不給您接種疫苗，而是等到您康復後再接種。
