Nak suruh you check dengan doktor or nurse kat clinic ya, sebab booster schedule tu boleh berbeza depending on which vaccine you took first and your age group, lagi-lagi now ada updates. A few of my mum friends took theirs, mostly mild side effects je like sore arm or slight fever for a day or two, but everyone's different. Best to confirm timing dengan healthcare provider you sebab they'll look at your medical history and give you the exact timeline, okay?
