There are serious worries about measles in Victoria. 

7 News is reporting that the Victorian Health Department has found that 13 people that were struck down by the disease since 2014 were vaccinated. 

The worry here is that the virus might have evolved beyond the latest vaccination. 

A third vaccination now might be needed to combat the public health scare. 

It comes as the US deals with the biggest measles outbreak since 1992.
