NBC News: Pfizer to begin Covid vaccine clinical trial in pregnant women

From the interview:

CARLEIGH KRUBINER: The CDC actually says that women should be offered the vaccine when they're pregnant and should discuss the risks and the benefits with their physician, so there is some guidance. One of the things we're missing is the definitive evidence to make more clear recommendations to say, 'yes, absolutely, this is safe, and you should feel free to go and get this,' and that is really what we'll get from these trials, is that reassurance.
