Boosters during pregnancy: Advice from the MOH:
It is recommended that pregnant people aged 18 and older receive a booster dose of the Pfizer vaccine to help protect them and their baby from the effects of COVID-19. The booster vaccine can be given at any stage of pregnancy at least 3 months after the primary course (for most people, this is two doses).
Pregnant people should discuss the timing of their booster with their midwife, obstetrician, or general practitioner.
