PETALING JAYA: Booster shots have lower rates of adverse events following immunisation (AEFIs) at only 0.1 cases reported per 1,000 doses, even lower than the number reported after primer doses, which stands at 0.4 cases every 1,000 doses.
National Pharmaceutical Regulatory Agency (NPRA) director Dr Roshayati Mohd Sani said the majority or 93% of reports received via the NPRA’s reporting system had been mild to moderate AEFI cases while serious events were recorded at the rate of 0.03 for every 1,000 doses.
