The first large, real-world study of the effectiveness of mRNA COVID-19 vaccines during pregnancy found these vaccines, especially two initial doses followed by a booster, are effective in protecting against serious disease in expectant mothers whether the shots are administered before or during pregnancy.

Pregnant women were excluded from COVID-19 mRNA vaccine clinical trials, so this new study fills a significant knowledge gap, providing strong evidence that vaccinating women who are or might become pregnant protects against hospitalization for the disease during pregnancy.
