SINGAPORE: Data in Singapore on the bivalent COVID-19 vaccines does not show an increased risk of ischaemic stroke linked to either of the updated Moderna or Pfizer-BioNTech shots, said the Ministry of Health (MOH) on Saturday (Jan 14).
The Health Ministry's statement comes after US federal health authorities launched an investigation into a preliminary safety concern about a potential increased risk of stroke in seniors who received the bivalent vaccine.
"In Singapore, the local data accrued for the bivalent vaccines at this time does not show an increased risk of ischaemic stroke after receiving either the Moderna or the Pfizer-BioNTech/Comirnaty bivalent vaccine," said MOH.
"The safety profile of the bivalent mRNA vaccines has been observed to be similar to that of their monovalent versions."
An ischaemic stroke, also known as brain ischaemia, is caused by blockages in arteries that carry blood to the brain.
The preliminary safety concern about the Pfizer bivalent shot was detected by one of the US Centers for Disease Control and Prevention's monitoring systems known as the vaccine safety datalink (VSD).
It uncovered a possible safety issue in which people aged 65 and older were more likely to have an ischaemic stroke 21 days after receiving the Pfizer-BioNTech bivalent shot, compared with days 22 to 44.
However, the US CDC said in a statement on Friday that it is "very unlikely" that Pfizer's bivalent COVID-19 shot carries an increased risk of stroke for people aged 65 and older.
No other surveillance system has detected a similar safety concern so far, said the health agency.
"A large study of updated (bivalent) vaccines (from Pfizer-BioNTech and Moderna) using the Centers for Medicare and Medicaid Services database revealed no increased risk of ischaemic stroke," said the US CDC.
It also noted that other countries have not observed an increased risk for ischaemic stroke with the updated bivalent vaccines, adding that the matter requires more investigation.
