There were 14 reports of suspected adverse events out of more than 230,000 booster jabs of Covid-19 vaccines given out since the national booster vaccination programme was rolled out on Sept 15.

The rate of suspected adverse events linked to the booster shots is 0.006 per cent, said the Health Sciences Authority (HSA) on Friday.

These reports described adverse events similar to those associated with the first two doses of the Pfizer-BioNTech/Comirnaty or Moderna mRNA vaccines, including rashes, swelling of the eyelids, face and lips, chest discomfort, shortness of breath, fever, generalised weakness and dizziness.

There were two reports of serious adverse events (0.0008 per cent of administered doses), describing blood clots in the veins of the legs and anaphylaxis, a severe life-threatening allergic reaction.
