Some governments and officials hope they could suppress the pandemic altogether.

一些政府和官員希望他們能夠完全抑制這場大流行。

But the concept comes with caveats on experts say such expectations are misplaced.

但這個概念是有注意事項的專家說，這種期望是錯誤的。

So some scientists are worried that the concept of herd immunity is being misunderstood.

是以，一些科學家擔心群體免疫的概念被誤解。

Um, they worry that people wrongly believe that it would be something that they can rely on as individuals to protect them, even if they don't get vaccinated.

嗯，他們擔心人們錯誤地認為，這將是他們作為個人可以依靠的東西來保護他們，即使他們不接種疫苗。

They also think there is a misconception about what's involved in achieving herd immunity.

他們還認為，對實現群體免疫力的內容存在誤解。

Estimations of the threshold we need to reach for herd Immunity varies depending on who you ask.

估計我們需要達到的群體免疫力的門檻，因問誰而異。

Most estimates say between 60 to 70% of the population needs toe have immunity of some form, either through vaccination or from previous infection.

大多數估計稱，60-70%的人口需要通過接種疫苗或以前的感染獲得某種形式的免疫力。

But all of that hinges on the elusive reproduction rate or our value, the measure of how much the virus is being transmitted on how much it is circulating.

但這一切都取決於難以捉摸的繁殖率或者說我們的價值，衡量病毒的傳播量有多大，就看它的流通量有多大。

So the R value is really important when it comes to trying to figure out what percentage coverage we need to get herd immunity with vaccines.

是以，當我們試圖計算出我們需要用疫苗獲得群體免疫力的覆蓋率時，R值真的很重要。

The problem is that we can't calculate the R value of this disease.

問題是，我們無法計算這個疾病的R值。

That's partly because it's a new virus on partly because we are not living in normal times.

這一方面是因為這是一種新的病毒，另一方面是因為我們不是生活在正常的時代。

Another unknown is whether vaccines will stop the transmission of the virus.

另一個未知數是疫苗是否能阻止病毒的傳播。

So the data we've seen so far from the front runner vaccines from Fighter by on Tech on DFO from Madonna do suggest that they are very good at preventing disease.

So there's a 90 to 95% efficacy rate in preventing disease.

所以在預防疾病方面有90～95%的療效。

This doesn't, however, mean that they will stop transmission of the virus.

不過，這並不意味著他們會停止病毒的傳播。

So some say, aiming for herd immunity is fruitless.

所以有人說，以群體免疫力為目標是沒有結果的。

What some of the experts that I've spoken to are saying is that what we should be focusing in on is protecting the most vulnerable people, so vaccinating the most vulnerable people, the old on those with co mobility's.

一些專家，我已經說過的是，我們應該關注的是保護最脆弱的人，所以接種最脆弱的人，老的那些與共同移動的。
