***VAERS is a short form for Vaccine Adverse Events Reporting System which is established in USA. In Malaysia, currently all matters regarding medicines and vaccines are controlled by Biro Pengawalan Farmaseutikal Kebangsaan (BPFK).

We do not have a system like VAERS (yet), but parents can submit an Adverse Effects Following Immunisation (AEFI) report to BPFK, by downloading this form down here,print it out and send it to BPFK if you suspect your child is having AEFI. AEFI may range from mild temporary effects to severe lifelong effects.
