My nephew’s wife had first shot then found out she is pregnant. Was told by air force doctors NOT to get second shot.
Praying this child is ok.
No evidence to think she and the child will be affected in any way. There are thousands of instances like what you describe and they happened during the clinical trials as well.
The American College of Obstetricians and Gynecologists states that: “no differences have been seen when comparing pregnant women participating in the v-safe pregnancy registry with the background rates of adverse pregnancy outcomes.” (https://www.acog.org/clinical/clinical-guidance/practice-advisory/articles/2020/12/vaccinating-pregnant-and-lactating-patients-against-covid-19)
