“ However, given the dearth of safety data of COVID-19 vaccines during pregnancy and the novelty of some COVID-19 vaccine candidate platforms (e.g. mRNA) , it is essential that vaccine safety data among pregnant persons is comprehensive and captured in near real-time. A novel smartphone-based active surveillance vaccine safety monitoring system, v-safe, is currently being developed to supplement the ISO’s immunization safety activities. As part of this surveillance activity, information on pregnancy status at the time of vaccination and at subsequent time points will be collected. ”
