SAN DIEGO -- San Diego County's newest weapon against swine flu has a major problem, 10News reported.

County health officials printed out 100,000 pocket-sized cards that detail symptoms of swine flu and tips on how to avoid the swine flu. The card also suggested two different places to get vaccinated.

Public Health Officer Dr. Wilma Wooten said she plans to print at least 250,000 cards and they will be available to the public, but they're targeting the homeless population, who are considered a high-risk community,

On Monday, members of the Alpha Project began handing out the cards to the homeless.

Bob McElroy, head of the Alpha Project, said, "This is a good start. If the swine flu hits this population, it's going to be catastrophic. They share food and other things, and they group together to survive. It will also burden local ERs and taxpayers."

So far, one transient has been hospitalized with swine flu, and county officials hope the cards will help keep numbers low.

However, while the cards urge each person to get vaccinated, there is very little vaccine to go around. Last week, county clinics ran out of the H1N1 shots, and the nasal spray version is not for everyone. Wooten said the next shipment is likely due in several weeks.

"It's frustrating for all local health departments. We're creating the demand for the vaccines, but there's not enough vaccines," said Wooten.

With the winter shelter to open downtown around Thanksgiving, the level of frustration may increase. As of now, it appears many residents at the shelter will not be vaccinated.

"We have several thousand high-risk, vulnerable people and they don't have access. If there's cases as this shelter is open, we could be in trouble," said McElroy.

McElroy also said he's negotiating to try and have a clinic on-site at the winter shelter once the vaccine arrives.
