Wa'alaikum assalam! Yah, banyak mommy kat sini ambil vaksin masa pregnant, especially yang nak masuk trimester ketiga macam you. A few of my mum friends took theirs around 7-8 months and everything went smooth je, the doctors mostly encourage it sebab protection untuk baby after birth is important. But since this is about vaccination during pregnancy, best la you confirm dengan your gynae or midwife first, because they'll know your full health picture and can advise you properly on timing and which vaccines are safe for you at this stage.
