Vaccination update.

Vaccination eligibility in Victoria will expand to include those in the 40 to 49-year-old age group for the Pfizer vaccine. 

Acting Premier James Merlino said 12,677 people got vaccinated in the past 24 hours, however he urged more people in Victoria to be willing to get vaccinated to mitigate the spread of the virus.
