In spaces where expectant mothers seek fellowship online, panic, frustration, and the predatory nature of anti-vaccine rhetoric are stark.
We've been going through this exact scenario with my sister and it's terrible. She's due soon and kept waiting and waiting because of the same types of fears you wrote about. She finally got her first shot about a week ago after a full family campaign to convince her. She was ready to wait until the child was born. I'm just relieved she did the right thing in the end.
My wife (former COVID ICU-nurse and expecting mother) practically begged her OB to let her get the booster shot. More evidence suggesting both in-utero protection and antibody transfer via breast milk is emerging every week. At the end of the day, everything we do has some sort of risk involved, so why not take the easy precautions?
The reporter at our shop who has been focused on COVID and COVID misinformation was pregnant while working on all of this, and wrote a piece about her own investigation of the risks: https://publicintegrity.org/health/coronavirus-and-inequality/pregnant-coronavirus-vaccine-liz-essley-whyte/
