This new study, from The Canadian National Vaccine Safety (CANVAS) Network, looked at data from participants across seven Canadian provinces and territories between December 2020 and November 2021. All vaccinated participants were asked to self-report any health events during the seven days following each dose of COVID-19 vaccine.
The unvaccinated pregnant control group was asked to record any health problems over the seven days before they filled out the survey. In total, 191,360 women aged 15-49 years with known pregnancy status completed the first dose survey and 94,937 completed the second dose survey.
The researchers found that 4.0% (226/5,597) of mRNA-vaccinated pregnant females reported a significant health event within seven days after dose one of an mRNA vaccine, and 7.3% after dose two. The most common significant health events after dose two in pregnant females were a general feeling of being unwell, headache/migraine, and respiratory tract infection.
In comparison, 3.2% of pregnant unvaccinated participants reported similar events in the seven days prior to survey completion. In the vaccinated non-pregnant control group, 6.3% reported a significant health event in the week after dose one and 11.3% after dose two.
