According to the White House, the president's daughters got the shot last week. The doctor is said to have used the vaccine from the health department of Washington, D.C.
The president himself and his wife, however, will wait until the priority groups, children, pregnant women, etc. have been vaccinated.
The girls allegedly did not get special treatment, like many people expect. Obama was pressed for this step to make parents lose their skepticism towards the vaccination and get their children swine flu shots as well.
