The daughters of US President Barack Obama, Malia and Sasha, have received their swine flu vaccinations, a White House spokesperson said.
The First Daughters were given their A(H1N1) shots last week by the White House physician, Katie McCormick Lelyveld, a spokesperson for first lady Michelle Obama, said on the White House blog.
Malia, 11, and Sasha, eight, were inoculated against A(H1N1) after the vaccine became available to school-age children across the nation's capital of Washington and surrounding areas.
The girls also have been vaccinated against seasonal flu, the White House said.
President Obama and First Lady Michelle Obama have not yet received their swine flu vaccinations, but have received their seasonal flu shots, according to Lelyveld.
Before getting their swine flu shots, the president and first lady will wait until the vaccine is made available to Americans not in the priority target groups, the White House said.
Those at greatest risk include pregnant women, people under the age of 24, and patients with underlying medical conditions which put them at greater risk of complications.
There is currently a national shortage of the swine flu vaccine, and a top US health official said the United States could face a shortfall of some 45 to 55-million doses by the end of the year, making it important that health officials carefully mete out the vaccine.
President Obama over the weekend declared a national emergency for doctors and nurses to better deal with the rapid spread of the virus that has infected millions and killed more than 1 000 people across the United States. - Sapa-AFP
