Honestly, pregnancy booster shots boleh tapi better check with your OB-GYN dulu sebab timing and which vaccine brand matter, they know your full medical history better than anyone online. I took my booster while preggy but my doctor advised me to do it in the second trimester, and honestly it's different for everyone depending on when you got your first two doses and how far along you are. Safest move is a quick call to your clinic rather than going based on what other mommies did, especially for something involving baby inside!
