COVID-19 vaccines in patients who are pregnant, are planning to become pregnant, are breastfeeding or are planning to breastfeed

The global health crisis created by the COVID-19 pandemic requires effective prevention strategies and therapeutic approaches at a worldwide scale. Regarding pregnant women, the observational studies have shown that pregnant patients have an increased risk of severe illness with intensive care unit (ICU) admissions, need for mechanical ventilation, death or adverse pregnancy course, with high risk of preterm birth and postpartum complications. It is challenging to counsel the pregnant patients about the efficacy and safety of the approved COVID-19 vaccines due to the lack of data from clinical trials. All worldwide international and national government agencies and professional associations take different position regarding the vaccination against COVID-19 in pregnant women, in those aiming to be pregnant and in breastfeeding patients. The solution to this public health issue is based on the development of COVID-19 vaccines in current and planned clinical trials. This paper aims to help physicians to implement the results of the clinical trials of COVID-19 vaccines by correctly inform, counsel and support patients who are pregnant, are planning to become pregnant, are breastfeeding or are planning to breastfeed.
