Pregnant women have been reassured it’s safe to have a Covid jab—but new research has discovered the vaccine nearly doubles the chances of a miscarriage.
Those given the Pfizer jab in the first 12 weeks of pregnancy (first trimester) are up to 91 percent more likely to have a miscarriage—a risk that is eight times higher than official figures have claimed.
Safety advice for having a Covid jab in early-stage pregnancy has been based on a report prepared by the US’s Centers for Disease Control and Prevention (CDC), which reckoned miscarriage rates among the vaccinated was around 12 percent, which is about the rate that would normally be expected anyway.
But the CDC researchers had excluded women in their first trimester and who were more likely to suffer a miscarriage. When those women are calculated back in, the rate of miscarriage rises by between 82 percent and 91 percent, researchers at the University of Auckland in New Zealand have said.
A miscarriage is possible up to 23 weeks of a pregnancy—but it is much more likely to happen in the first trimester.
The CDC had presented “falsely reassuring statistics”, the New Zealand researchers say. The agency had tracked the pregnancies of 827 women given the Pfizer jab, but 713 of them had been given the jab when they were close to, or had started, their third trimester.
