Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that COVID-19 vaccination during pregnancy does not increase the risk of preeclampsia?

Partly. Several cohort and meta-analytic sources report that COVID-19 vaccination in pregnancy was not associated with increased preeclampsia or related hypertensive outcomes, though most address broader perinatal outcome sets rather than preeclampsia specifically. One study of women undergoing assisted reproduction found inactivated vaccination before embryo transfer was associated with increased pregnancy-induced hypertension risk, so the evidence is mixed and only partial.
