Authorities have yet to get to the bottom of the flu vaccine scare in Western Australia, with tests so far showing no signs of abnormalities.
Chief medical officer Jim Bishop says there is a possibility a spike in cases of fever and convulsions for young children in WA could simply be linked to the higher number of vaccinations performed there.
He’s sought to reassure the public once more following last week’s moratorium on seasonal flu vaccinations for children aged under five.
To date there have been 57 cases in WA, compared to six in Victoria, four in NSW and Queensland, two in South Australia and one each in Tasmania and the ACT.
Tests conducted by the manufacturer, the Therapeutic Goods Administration and other independent experts have so far failed to pinpoint a possible cause, Professor Bishop said.
“We don’t have evidence at this time that there’s any abnormality with the batch or with the vaccine,” he said.
