Teratogenic window	Pregnant individuals with congenital fetal anomalies identified, No./total No. (%)			OR (95% CI)^a	OR (95% CI)^b
Teratogenic window	Unvaccinated or vaccinated outside teratogenic window	Vaccinated within teratogenic window	Vaccinated outside teratogenic window	OR (95% CI)^a	OR (95% CI)^b
30 d Before conception to 14 wk gestation	88/2007 (4.4)	48/1149 (4.2)	61/1473 (4.1)	0.95 (0.66-1.36)	1.01 (0.69-1.48)
