Many parents will not be getting their children vaccinated against the swine flu.

A new ABC News/Washington Post poll says nearly four in 10 parents will skip the shot for their kids.

By far, the biggest reason why these parents won't be vaccinating? Potential side effects.

Three in 10 adults say they are not confident the vaccine is safe.

More than 800 people have died from the H1N1 virus in America since April, and more than 4,000 have died worldwide.

Swine flu hits children, young adults and pregnant women the hardest.
