wud suggest avoid taking in 1st trimester , as it's live attenuated . Take after 12 - 14 weeks of pregnancy

Corona vaccines are safe in pregnancy. As a general teaching, we learned to avoid any live attenuated vaccination during first trimester of pregnancy (12-14wks). So if you don’t want to miss second dose you can take it or delay until completion of first trimester. In medical field, if benefit is more than risk we take that risk.
