Australian teenagers will be getting a free vaccine to protect them against four strains of the potentially deadly infection meningococcal.
The combined vaccine for meningococcal strains A, C, W and Y will be available at no cost to Australians aged 14 to 19 from next April.
The change is being listed for the age group on the National Immunisation Program, which provides free jabs.
More than a million teenagers are expected to get the vaccine in the next four years.
The listing for adolescents had been recommended by the Pharmaceutical Benefits Advisory Committee.
It comes after the jab became freely available for 12-month-olds in July.
Health Minister Greg Hunt said the bacterial infection, although rare, can be deadly.
It killed 28 Australians last year, compared to 11 in 2016 and 12 in 2015.
"The consequences are devastating for individuals and their families," he said.
The federal government has also been under pressure to list a vaccine for the B strain of meningococcal on the National Immunisation Program.
But the prime minister has said the change cannot occur until the vaccine earned the recommendation of an expert committee.
He has urged the company that makes the vaccine, GlaxoSmithKline, to have another attempt at becoming listed on the program.
The company confirmed in August it would consider the move but only after it had the results of a South Australian study on the impact of the vaccine, Bexsero, on meningococcal B immunity in 2019.
