Aiyooo, don't worry lah, better late than never! You can go to your nearest Klinik Kesihatan (government clinic) or private clinic in JB and just tell them you missed the vaccines; they will tahu what to do and catch him up properly. A few of us mums have been in the same boat, and the nurses very understanding one. Bring his vaccination card and they'll schedule him accordingly, no problem at all!
