句意:——我想知道中国科学家是如何研制出COVID-19疫苗的。——我不知道。让我们在网上查资料吧。考查交际用语。I have no idea.我不知道;You're welcome.别客气,不用谢;Don't mention it.不足挂齿,没关系;What a pity!真遗憾。由“Let's find the information on the Internet.”可知,答者不知道中国...
No. Different COVID-19 vaccines use different technologies, or “platforms”. The most conventional one is the inactivated vaccine. It contains dead virus. Because the virus is still whole, it has all of the parts, in the correct shape, that can stimulate a response from the immune system ...
How is the vaccine given? It is given by injection(注射).There are several ways to get injected.For the most common way,you are supposed to get it twice.After the first injection,you have to get the second one. Is the vaccine bad for human bodies?
Your immune system also has a pretty good memory, so it will spring into action again should you ever become exposed to the real virus. Every vaccine is different, and it's not clear how long immunity for a COVID-19 vaccine may last. But the benefit of a vaccine is that it gets ...
That will not be true for a COVID-19 vaccine or therapeutic. Society will demand the shortest possible timeline. Once a successful vaccine is confirmed, manufacturers will be under extreme pressure, and tech transfer will need to happen as soon as possible, within a f...
This work studies the impact of the two main events in 2020 on companies閳 tock exchange activities: announcing COVID-19 as a world pandemic and announcing the first coronavirus vaccine. This study was carried out by an event study methodology using Nasdaq-100 data. Ordinary Least Squares (OLS...
The COVID-19 vaccines have been proven to be safe and effective, but many patients still harbor concerns. These concerns can affect whether they give the vaccine to their children, or even their opinions on childhood vaccines. Steven. P. Furr, M.D., president of the AAFP, discusses the...
Vaccine developers who have already reported promising phase III trial results against COVID-19 estimate that, between them, they can make sufficient doses for more than one-third of the world’s population by the end of 2021. But many people in low-income countries might have to wait until...
“Among COVID-19 patients, those who have organs involved other than the lungs are most at risk of a bad outcome,” said Deb, who is also a cardiologist and professor of molecular cell and developmental biology. “So we felt it was really important to understand how the virus affects thos...
As soon as the genetic composition of a new virus has been mapped, we can code its key components to make synthetic mRNA, which we then introduce into the body in the form of a vaccine. In this case, we use it against COVID-19. ...
