A West Australian Health Department official says the COVID-19 vaccination rate in the Pilbara is "disappointing" and more vaccine supply is needed in the region.
Just 2.5 per cent of the population in the Pilbara has been fully vaccinated, which is well below the state average of 6.4 per cent.
The Department of Health's chief operating officer of the COVID-19 vaccine program, Sue Kiely, said the Pilbara's vaccination rates were the lowest in the state.
"It's disappointing because we'd love to get everybody vaccinated as soon as possible," she said.
She could not say exactly why the region had the lowest rate, but said 70 per cent of vaccinations were being done through public hospitals and community clinics.
"We've had the GPs doing about 21.5 per cent of the vaccines in the region and the [Aboriginal Medical Services] have been picking up about 8.5 per cent," Ms Kiely said.
"In other areas, the primary care sectors have been able to pick up a bit more, so we are really hoping that we could get the Pilbara rate up by advocating for more vaccine to be supplied to the AMS's and GPs.
State Nationals Leader Mia Davies said regional COVID-19 vaccination clinics were only available in certain locations and on certain dates.
Ms Davies said she would like to see rolling COVID-19 vaccination clinics in the north of the state to make it as easy as possible for locals to get vaccinated.
"We know that it's human nature if you try to book in and you can't book in, sometimes it takes a bit for you to go back and do it," Ms Kiely said.
"So, what we need to do is make it as easy as possible for everyone to get their vaccination."
