LAS VEGAS -- Twenty people living in Clark County have died of H1N1 this year.

With the shot in short supply, the flu mist is the best option. But people are reluctant to get the mist, causing them to go unvaccinated.

Survey: Will You Get The H1N1 Vaccine?

The Southern Nevada Health District said they do the same thing, but the urban legends about the mist have spread so much that it's caused the public to shy away. That's a potential health problem, and it's an issue that affects supply and demand.

On Saturday, the health district will offer H1N1 vaccines at their main office and in Henderson. There are a limited number of shots, but plenty of nasal mists.

Shots will only be given to priority, high-risk groups like pregnant women, health care workers, people between 6 months and 24 years old and those who care for children.

“We are trying very hard that people who qualify for injectables only receive injectables and people who qualify for flu mist only receive flu mist,” said Bonnie Sorenson, of the health district.

The problem is most people want the shot, and the health district is not verifying priority status.

“It's an honor system,” Sorenson said.

That depletes the supply faster, and with only 3 percent of the high-risk population receiving the shot so far, it could lead to a larger outbreak.

But what's the difference between the shot and the mist?

“The H1N1 shot is an injection of the killed form of the virus whereas the nasal spray is a live, weaker version of the virus,” said family medicine physician Dr. Daliah Wachs.

Wachs said a lot of people have aversions to nasal sprays in general. Then there's the myth that they'll actually get H1N1 from the live version of the mist, something that's not true Wachs said.

“I have never seen anyone get the flu from the flu mist, even the seasonal flu vaccine. I have never seen that happen, and it's supposedly a very safe vaccine,” Wachs said.

While the health district said people don't have a choice of vaccines, the honor system philosophy could be a concern.

“We need our children and the priority group to get it. They need to check who's getting the injection before giving it to them,” Wachs said.

She said she's not sure when or if she'll get any of the H1N1 shots because the supply is so low. Wachs said it is almost the peak of flu season.

Since it takes a few weeks for the immunity to build up, it's important to get the vaccine before the end of December.
