VCE students have been declared a priority for vaccinations.
Mental Health and Education Minister James Merlino said he was particularly concerned about Year 12 students in their final months of school, announcing they would be a priority for vaccinations.
"The priority for us is to make sure that all final year students have received their vaccination before they start sitting their exams on 4 October," he said.
"That is our priority.
"Whether that is through the many state vaccination hubs we have got across Victoria, whether it is through GPs or whether it is through GPs or whether it is through participating pharmacies."
ATAGI is now looking to approve the Pfizer vaccine for use in children between 12 and 15.
