BioNTech-Pfizer 和 Moderna 对COVID 19近期的数据比较

之前，BioNTech说他们的疫苗对于Delta是有效的，无需更改处方。而刚刚有报道把BioNtech疫苗和Moderna的对delta病毒作比较。大家估一下那个更为有效？

BioNTech said its vaccine developed with Pfizer works against the Delta strain and does not need to be modified yet. They have shipped around 1 billion doses of their vaccines to more than 100 countries, and expect to generate US$33.5 billion in sales this year!

A recent Mayo study (in July, in Florida) shows that the risk of suffering a breakthrough COVID-19 infection with the delta variant after being fully vaccinated with the Moderna vaccine may be much lower than the risk for those who received the Pfizer vaccine! The risk of a breakthrough case was 60% lower for Moderna recipients as compared to Pfizer recipients.  Another study (in Minnesota) also shows that Moderna vaccine was 76% effective at preventing infection, but the Pfizer vaccine was 42% effective.

报道指Moderna疫苗是较为有效。其实，Pfizer-BioNtech也不差。

Dr.Rex认为不要等「最好」的疫苗出現, 以下是他的观点：

NEW YORK (WABC) -- A winter weather advisory is in effect for the New York area due to concerns over black ice after Wednesday's winter storm. 

Snow that began overnight transitioned to sleet and freezing rain across the Tri-State area Wednesday, making for incredibly dangerous conditions on the roads and sidewalks. 4 inches of snow and a quarter inch of ice fell in Central Park.

Parts of New Jersey saw close to 6 inches. Danbury, Ct. had 9 inches, and accumulations reached upwards of a foot in areas in higher elevations. The highest reported total was 12.5 inches in Newburgh.http://abclocal.go.com/wabc/story?section=weather&id=9418734

The zero degree fahrenheit. 華氏零度

Right after the flight landed on the soil of NJ airport on Thursday evening, snows started. I didn't go back to my office on Friday but worked at my habitat on Friday. This morning, I got onto my car, I realized that it was 0 deg F. I couldn't remove the ice on the window shield, I turned on the engine and warmed up the car. It took 30 minutes for the ice to melt. I drove extremely slowly in the resident area, as ice was on the street surface. I took some pictures and posted them in this album. 

緊接著航班降落，積雪開始。在星期五我沒有回到辦公室。今天上午，我到了我的車，我意識到，這是華氏0度樓。我不能滅在窗口屏冰，我打開發動機。花了30分鐘，冰融化。我開車極為緩慢在居民區，因為冰是在大街上表面。我拍了一些照片，並張貼他們的這張專輯。
