President Barack Obama's daughters, Malia and Sasha, have received their swine flu shots.

A spokeswoman for First Lady Michelle Obama, said, on Tuesday that 11-year-old Malia and 8-year-old Sasha received their H1N1 shots last week from a White House doctor after the vaccine became available to school-children in the Washington, DC, area.

Priority groups

The spokeswoman, Katie McCormick Lelyveld, said the president and Mrs Obama would wait to get their shots until after people in priority groups, such as children, young adults and pregnant women, have received their H1N1 vaccinations.

All four of the Obamas already have received their seasonal flu shots.
