Hi mama! Honestly, best talaga to ask your OB directly kasi iba-iba ang formulations at yung vaccine brand na specifically recommended para sa pregnancy ay important para sa safety ng baby mo, a few of us moms din nag-ask sa doctors namin before getting any vaccine during pregnancy kasi mapapaisip ka lang kung okay talaga. Your OB would know exactly kung bakit nila recommended yung specific brand or clinic para sa iyo, so don't hesitate to clarify with them!
