The first families seeking H1N1 vaccinations lined up at 5:30 a.m. today outside Oklahoma City Community College.
By the time immunizations started at 9 a.m., thousands were lined up in the early chill, wrapped in coats and blankets.
The Oklahoma City-County Health Department is offering free shots and nasal spray vaccinations to pregnant women and children ages 4 to 18. As more doses come into the state over the next weeks, additional groups will be offered immunizations against H1N1, also called swine flu.
The clinic is planned to last until 6 p.m., but likely will end early as the 4,000 doses are depleted. The clinic was planned to coincide with fall break at many Oklahoma County schools.
Jennifer and Jeff Babek even changed plans to leave town so they could get immunizations for their daughters, ages 3 and 7.
"We were on our way out of town last night, when we heard this on the news," said Jennifer Babek. "We decided to turn around."
