More than 2,600 people stood in line — sometimes longer than two hours — to be among the first in southern Nevada to get the injectable swine flu vaccine.

Gwen Osburn, community health nurse at the Southern Nevada Health District, said more than 300 people were vaccinated in the first hour after opening on Saturday.

The health district has received more than 48,000 doses of the H1N1 vaccine, including an initial delivery of 20,000 FluMist doses, which are administered through the nose.

About 11,000 doses have been distributed to doctors' offices in Clark County that serve at-risk populations.
