The Pentagon says a small shipment of swine flu vaccine has arrived at the Guantanamo Bay military prison. It's unlikely any of the terror detainees held there will get any of the sought-after vaccine now.

The possibility that detainees would get vaccinated became a political and public relations headache for the Obama administration at a time when many Americans are still waiting for doses that are scarce.

Pentagon spokesman Bryan Whitman says approximately 300 doses arrived at the prison in Cuba on Monday. That's not enough to cover all of the troops and health care workers who would get their vaccinations ahead of the detainees.

Detainees still could receive vaccinations, after all the highest-priority troops and employees are treated.

Some civilians who work at the Pentagon itself got their shots on Monday.
