HONOLULU -- State health officials on Thursday said they hope enough swine flu vaccine arrives in Hawaii in time to prevent massive outbreaks.

They briefed media day on latest developments with the H1N1 flu pandemic. At their weekly briefing they said the H1N1 vaccine is trickling in. They said they wished it would come sooner, and they are allocating it to priority groups.

At this point, the Centers for Disease Control and Prevention has allocated more than 146,000 doses of vaccine for Hawaii, state health officials said.

"We share everyone's frustration about the speed with which the vaccine is not getting out to the general public. The priority groups have remained the same and we encourage folks in those groups to consider being vaccinated," state Health Director Dr. Chiyome Fukino said.

The health director said 90,000 doses are earmarked for school clinics. The vaccine will be given to priority groups.

Priority Groups:

Pregnant women

People who care for infants

Healthcare and emergency personnel

Children

People existing health conditions

Doctors cannot predict when it might peak, but are hoping it might not be as bad in Hawaii as on the mainland.

"Unlike all the other mainland states we've had pretty much baseline activity for this time of year even now. Unlike them we have vaccine here. It's trickling into the state slowly, but it is coming so we have this chance to potentially not see the activity you're all hearing about on the mainland national news media," state epidemiologist Dr. Sarah Park said.

Children under the age of 10 are advised to get two doses, but right now officials are focusing on getting at least one dose to as many people as possible.

"Once we've got a good number of people in the priority group with the first dose then we can focus on the second dose, but we need to get that first dose into as many people as possible right now," Park said.
