Lucas Walsh is desperate to see his grandparents and get back to school.

So it is no surprise the 12-year-old was rolling up his sleeve on the very first day he was eligible to receive the Pfizer COVID-19 vaccine.

Mum Linley said, like most pre-teens, he was keen to get back to normal life and had no anxiety about getting the jab.

"It sucks to be stuck at home," Lucas told AAP.

The Eaglemont tween is looking forward to getting back to school and seeing his grandparents.

"They are the best," he said.

Another 12-year-old, Harry Goodison, is keen to be back at school and able to see his friends, and says that is why he got the vaccine on Monday.

For mum Sarah, seeing her son get the jab as the virus continues to circulate was a comfort.

"The numbers are going up and the realisation that it will be in our community sooner or later, having him vaccinated, it just gives the peace of mind," she said.

These two Victorian youngsters were among the first to take advantage, after Prime Minister Scott Morrison announced in August that as many as 1.2 million 12-15 year olds would be able to book a Pfizer vaccine from September 13.
