President Obama's school age daughters have not been vaccinated against the H1N1 flu virus.  White House Press Secretary Robert Gibbs says the vaccine is not available to them based on their risk. 

The  Centers for Disease Control recommend that children ages 6 months through 18 years of age receive a vaccination against the H1N1 flu virus.  At this time only children with chronic medical conditions are receiving the vaccination because their immune system is not strong enough to fight off the strain.  The CDC also says a regular seasonal flu shot does not protect against the virus.
