A booster dose can be considered if you are 18 years, or older, and had your initial COVID-19 vaccine course (called the primary course) ≥ 6 months ago. Pfizer is the preferred brand for booster doses for all people, including in pregnancy, regardless of the brand used initially.
mRNA vaccines are safe and effective for those trying to conceive, pregnant and breastfeeding women. Booster doses have not yet been studied in those who are pregnant, but have been shown to be safe and effective in non-pregnant adults.
We do know that COVID-19 infection in pregnancy poses a significant risk for mothers and their babies, RANZCOG recommends that pregnant women receive booster vaccinations in line with the recommendations for the non-pregnant adult population.
