Our results demonstrate no apparent increase in the risk of miscarriage among pregnant women who received the COVID-19 vaccines, which was consistent with the rate of miscarriage in the general population before the pandemic (Quenby et al., 2021). Compared to unvaccinated women, those who received the vaccine had a slightly higher risk of miscarriage, though this was not statistically significant. This trend could be explained by several confounders, such as population socio-economics, baseline risk factors (e.g. recurrent pregnancy loss), co-morbidities, and access to healthcare services, which were observed in cohort studies evaluating third-trimester pregnancy outcomes among vaccinated women (Fell et al., 2022; Magnus et al., 2022). There was no significant difference in the RR of live birth or ongoing pregnancy among women who received COVID-19 vaccination compared to those who did not receive a vaccine.
