Evidence from an Israeli hospital
Data from Rambam hospital in Haifa reveal a stillbirth, miscarriage and abortion (SBMA) rate of 6% among women who never received a COVID-19 vaccine, compared to 8% among women who were vaccinated with at least one dose (and never had a SARS-Cov-2 infection).
That’s a statistically significant odds ratio of 1.36 (CI 1.0-1.9), meaning your odds of having a stillbirth, abortion or miscarriage are 1.36 times higher if you are vaccinated.
Another way of putting it is that the SBMA rate among vaccinated women was nearly 34% higher than the rate among unvaccinated women. This difference is statistically significant at the 95% confidence interval based on a Chi-square test of significance.
