Parkland Hospital is set to receive its doses on December 15. Dr. Joseph Chang, the Chief Medical Officer at Parkland, is not requiring all of the medical staff to get the vaccine but says he will be getting the shots because he is so comfortable with the science behind it. “I personally know a couple folks on these review boards, they, they take safety of the treatment more seriously than they take the effectiveness of the treatment,” he said.

Moderna’s vaccine, which was about 95 percent effective in trials, has not yet received approval, but most are predicting it will get the green-light sometime this week. As it stands, the U.S. is set to buy 100 million additional shots of Moderna’s vaccine — doubling the initial order.
