Federal health officials promise more doses of the hard to find H1N1 vaccine are on the way. But for many parents, the only thing harder than finding the vaccine, is deciding weather or not to have their kids vaccinated. Tricia Lensmeyer says having her three sons vaccinated was a difficult decision.

"It was a little bit, but so many kids have been sick that, I mean they say it's safe, so you know, we are just trusting that it will be." Says Tricia.

Tricia's son Andrew was sick for weeks with the swine flu. She says she doesn't want her other sons to go through what he did. At Collin County Pediatrics, the phone rings all day with questions about the vaccines safety. Dr. Jay Schwartz says he's given out about a hundred doses and so far there have been no callbacks about the vaccine.

"At this point they've shipped about 30 to 40 million doses of the vaccine, so if there was anything bad about the vaccine, I think it would have popped up by now." Says. Dr. Schwartz.

Dr. Schwartz is so confident about the vaccines safety, he and his two sons have been vaccinated.

"Well, I have researched it very thoroughly and I believe in the safety of the vaccine, so when I tell the parents that I've given it to myself and my children, that allays a lot of the fears about the vaccine." Says Dr. Schwartz.

Health officials say the vaccine is made exactly the same way the seasonal vaccine is produced. Still, many people fear the vaccine was rushed to the market. After much consideration, Carline Alies had her sons vaccinated because she says they all have asthma.

"Actually, just this morning. I wasn't sure about it, I struggled with the decision weather to have then take the shots or not." Says Carline.

They did, and she says she's not sure she made the right decision.

"I'm nervous. I'm just waiting to see because I understand they can have a reaction soon after the shot, so I'm just keeping my fingers crossed." Says Carline.

A recent Harvard study found that 41% of those surveyed said they would get the vaccine while 40% said they would not.
