I can think of pretty big number of things that are shocking in this entire COVID situation (most of which you would disagree with

), but I don't understand why this would be shocking.
I mean, I do understand that if you don't trust, don't want or think you don't need a vaccine, it would be shocking. Other than that, I don't see it. If it's deemed safe for pregnant women, which it is, the next logical step would be encouraging those women to get the vaccine.
