| Singapore: Reports of febrile seizures with measles, mumps, rubella and varicella (MMRV) combination vaccine |
| |
From January to October 2013, Health Sciences Authority received 13 reports of seizures following MMRV vaccination, as compared to six in 2012. Of these reports in 2013, 85% concerned febrile seizures occurring within three weeks of vaccination with Priorix-Tetra (GlaxoSmithKline Pte Ltd), which is the MMRV vaccine used predominantly in Singapore. Seven and five children received the first and second dose of the MMRV vaccine, respectively. The dose given to the remaining child was not specified. Four children were reported to have personal or family history of seizures. All recovered shortly after the seizure episode.
The risks of febrile seizures with MMR and MMRV vaccines are well established. Healthcare professionals are recommended to provide counselling to parents/caregivers about the possible risk of febrile seizures post-MMRV vaccination and the management of such events.
