Pregnancy Loss and Neonatal Outcomes in Published Studies and V-safe Pregnancy Registry Participants.
Among 827 participants who had a completed pregnancy, the pregnancy resulted in a live birth in 712 (86.1%),
in a spontaneous abortion in 104 (12.6%),
in stillbirth in 1 (0.1%), and in other outcomes (induced abortion and ectopic pregnancy) in 10 (1.2%). A total of 96 of 104 spontaneous abortions (92.3%) occurred before 13 weeks of gestation (Table 4),
and 700 of 712 pregnancies that resulted in a live birth (98.3%) were among persons who received their first eligible vaccine dose in the third trimester.
Adverse outcomes among 724 live-born infants ― including 12 sets of multiple gestation ― were preterm birth (60 of 636 among those vaccinated before 37 weeks [9.4%]), small size for gestational age (23 of 724 [3.2%]), and major congenital anomalies (16 of 724 [2.2%]);
no neonatal deaths were reported at the time of interview. Among the participants with completed pregnancies who reported congenital anomalies,
none had received Covid-19 vaccine in the first trimester or periconception period, and no specific pattern of congenital anomalies was observed.
Calculated proportions of pregnancy and neonatal outcomes appeared similar to incidences published in the peer-reviewed literature (Table 4).
妊娠の結果、712人（86.1％）が生児を出産し、104人（12.6％）が自然流産、1人（0.1％）が死産、10人（1.2％）がその他の結果（人工妊娠中絶および子宮外妊娠）を得ました。104件の自然流産のうち96件（92.3％）は妊娠13週以前に発生しており（表4），
生児を出産した712件の妊娠のうち700件（98.3％）は，対象となるワクチンの初回接種を妊娠第3期に受けた人であった．多胎妊娠の12組を含む724名の生児の副反応は，早産（37週以前に接種した636名のうち60名［9.4％］），
妊娠期間に対して体格が小さい（724名のうち23名［3.2％］），主要な先天異常（724名のうち16名［2.2％］）であったが，
面接時に新生児死亡の報告はなかった．先天異常を報告した妊娠完了者のうち、妊娠第1期または妊娠前後にコビッド-19ワクチンを接種した者はおらず、
先天異常の特定のパターンは観察されなかった。妊娠および新生児の転帰の計算上の割合は、査読付きの文献で発表された発生率と同様であった（表4）。
