Booster vaccine in 1st trim

I took my first jab when I was at week 5-6 (not knowing I m pregnant), then I dragged my second jab (till MOH don’t allow me to drag) also around first to early second trimester. Then I went for my booster jab in my third trimester. Baby is still super active and he’s coming out soon. I think of it that it’s an extra antibody for my boy, which my girl didn’t have any, which makes me very worry for her that one day she might has covid and suffer.
