US scientists monitored 43,000 pregnant women including 1,300 who tested positive for Covid. None had been vaccinated during the study, or tested for immunity to the virus from previous infection.
Edinburgh study of nearly 90,000 mothers-to-be shows unvaccinated pregnant women are four times as likely to have a extended perinatal death and twice as likely to have a premature birth.
An Intensive Care National Audit and Research Centre report reveals that of the 558 pregnant or recently pregnant women admitted to ICU from May 1-Dec 24, 118 were put on ventilators within 24 hours.
