“CDC has a great track record when they’re basing their decision on preliminary data that maybe isn’t available quite yet to the general public,”Pettigrew.

But, should we just take their word for the data without seeing it ourselves?

“I wouldn’t want them to wait weeks or months until publication, If they know something that would keep us safer, they should come out and say it, then we see the data when it comes out,”Pettigrew.

“Things may change again and they may change for the better or they may change for the worse and it all will depend on our actions now,”Pettigrew.
