More than 50,000 doses of meningococcal vaccine have been delivered to general practitioners, pharmacists and clinics across Tasmania following an outbreak of the disease in July.
But public health officials have said that thousands more young Tasmanians are still eligible for free vaccinations.
Director of Public Health in Tasmania, Doctor Mark Veitch, said there was still some way to go.
"We know that we have delivered the vaccine to a fair proportion of Tasmanians under the age of 21 but we are probably only about half way there, if that," he said.
"There are still plenty of people who we would like to take up one or another opportunity to get the vaccine over the next two to three months."
An average of six cases of meningococcal infection are recorded in Tasmania each year.
"As well as the recent outbreak of meningococcal infection in the northern suburbs, Tasmania as a whole has had the highest rate of meningococcal W infection for most of the last couple of years so this is an important preventive measure against that infection," Dr Veitch said.
"It was very unusual to have as many cases as we had in the second half July, but unfortunately we may well expect to have further cases at some stage later this year."
The state's Public Health Service is calling on Tasmanians under the age of 21 to take advantage of a second free Meningococcal disease vaccination clinic being held in Hobart today.
Five thousand Tasmanians were vaccinated at the clinic at the Derwent Entertainment Centre (DEC) in Glenorchy earlier in the month, with 1,000 people coming through the doors of a second free clinic yesterday.
An additional 2,000 people are hoped to be vaccinated against the A, C, W and Y strains of the disease today.
Doctor Veitch encouraged Tasmanians to come to the clinic with around 1,000 spaces still available.
"It is quite a quick process. Most people will be in and out within an hour," he said.
"If they don't choose to come to the DEC there will still be other options but it is a good opportunity."
The clinic is open between 9am and 6pm today at the Derwent Entertainment Centre and bookings can be made online here: www.health.tas.gov.au
