有這樣的研究很好!只是有一事不明:明明已接種的人已佔八九成,為何該研究選取的樣本人數卻是未接種孕婦三倍半於已接種孕婦呢?
The rate of preterm birth was roughly five per cent among more than 10,000 women who received at least one dose of a COVID-19 vaccine, compared to seven per cent for roughly 36,000 unvaccinated women, researchers said on Tuesday in the CDC's Morbidity and Mortality Weekly Report. The difference was not deemed to be statistically significant.
另外,該研究貌似只研究了早產和嬰兒體重不足的病例,而沒有提及嚴重性大得多外界關注也最多的的Still Birth病例。是我沒看見嗎?
科学研究报告需要时间,数据截止到7月份。。。那时候美国的接种率不会有八九成,现在可能也没有。

This report describes how COVID-19 vaccination during pregnancy was not associated with preterm or small-for-gestational-age at birth compared with unvaccinated pregnant women.www.cdc.gov
有中国的数据吗?
中国疫苗接种率高,过去两年中国孕妇的情况如何?
