evidence: The risk of miscarriage following COVID-19 vaccination: a systematic review and meta-analysis - PMID: 36794918 - PMCID: PMC10152171 - DOI: 10.1093/humrep/dead036 [...] Summary answer: There is no evidence that COVID-19 vaccines are associated with an increased risk of miscarriage. [...] Main results and the role of chance: We included data from 21 studies (5 randomized trials and 16 observational studies) reporting on 149 685 women. The pooled rate of miscarriage among women who received a COVID-19 vaccine was 9% (n = 14 749/123 185, 95% CI 0.05-0.14). Compared to those who received a placebo or no vaccination, women who received a COVID-19 vaccine did not have a higher risk of miscarriage (risk ratio (RR) 1.07, 95% CI 0.89-1.28, I2 35.8%) and had comparable rates for ongoing pregnancy or live birth (RR 1.00, 95% CI 0.97-1.03, I2 10.72%).
