Constraining factors.

限制性因素：

The first is getting enough supply quickly enough, and the second is the ability to administer the vaccines quickly.

第一是要快速獲得足夠的供應，第二是要有快速注射疫苗的能力。

Once they're produced and sent out to the sites, we're taking action to increase supply and increased capacity.

一旦生產出來併發往各工地，我們就會採取行動，增加供應，提高產能。

But even so, it will be months before everyone who wants a vaccine will be able to get one.

但即便如此，要想讓每個想打疫苗的人都能打到疫苗，還需要幾個月的時間。

Any stockpile that may have existed previously no longer exists.

以前可能存在的任何庫存都已不復存在。

Our practice is to maintain a rolling inventory of 2 to 3 days of supply that we can use to supplement any shortfalls in production and to ensure that we are making deliveries as committed.

我們的做法是保持2至3天的滾動庫存，用於補充生產中的任何短缺，並確保我們按承諾交貨。

But we're passing doses directly along two states very much in real time as they order them.

但我們是直接沿著兩個州非常實時地傳遞劑量，因為他們命令他們。

Pfizer and Madonna are committed to delivering a total of 200 million doses by the end of March, with much of it coming at the end of the quarter so it will accelerate.

輝瑞和麥當勞承諾在3月底之前交付總計2億劑量的藥物，其中大部分是在本季度末交付的，所以它會加速。

Pfizer yesterday announced that they think they can deliver 120 million doses this quarter, and as you heard from the president yesterday, United States plans to purchase an additional 200 million doses for Madonna and Pfizer this year, which will be sufficient to vaccinate every American over the age of 16, and we expect those doses this summer.

輝瑞公司昨天宣佈，他們認為他們可以在本季度提供1.2億劑疫苗，正如你昨天從總統那裡聽到的那樣，美國計劃今年為麥當娜和輝瑞公司購買額外的2億劑疫苗，這將足以為每個16歲以上的美國人接種疫苗，我們預計這些劑量將在今年夏天。
