New research shows kids need H1N1 shot

AZUSA, Calif. Thousands lined up in Watts for the H1N1 flu shot and even more circled the block in Azuza.

Denise Moreno and her three kids waited in line for five hours. She knows that it will be good for her children.

"I don't want them to get the flu. I have heard a lot of bad things about it," said Moreno. "I just don't want anything to happen to them."

New research sheds new light on why vaccinating children is important for everyone. Government scientist say vaccinating kids may help slow the spread of the constantly changing flu virus.

"First of all you are protected from the virus and infection," said City of Hope infectious disease expert Dr. Ito. "When it mutates it ends up being a weaker virus."

In the study, researchers from the National Institutes of Health found that vaccinated animals injected with the H1N1 flu virus had mutations that were more difficult to spread.

When scientist injected the virus into mice that were not vaccinated the strain mutated back into an easier to spread version. In people, scientist say the less children that are vaccinated, the more likely the strain they catch becomes a kind that is easy to spread.

"If you treat or vaccinate those who spread the most in the population that would be the most effective way of putting a halt to the pandemic," said Dr. Ito.

So when all of the Moreno kids get their shots they will be protecting more than themselves.

"That is why I am getting them vaccinated, I just don't want anything happening to any of them or to us," said Moreno.
