Atlanta , Georgia ( CNN ) -- The first daughters have gotten it along with other children , and more residents around the nation may soon be able to get the H1N1 flu vaccine as health officials say more is on its way . According to a statement posted on the White House Web site by Catherine McCormick-Lelyveld , press secretary for first lady Michelle Obama , daughters Sasha and Malia received their H1N1 and seasonal flu vaccines last week . The president 's daughters received the vaccine `` after the vaccine became available to Washington , D.C. , schoolchildren , '' according to the statement . Since Friday , about 6 million more doses of H1N1 flu shots and nasal spray have been released . `` We have 22.4 million doses available for shipment out directly to providers and we 're getting to the level where it will become significantly easier to find and receive vaccine . '' Dr. Thomas Frieden , director of the Centers for Disease Control and Prevention said Tuesday during a press conference . Frieden told reporters , `` We wish it had been available weeks or even months earlier but we 're beginning to get to a significant increase in the availability . '' The CDC had hoped that about 40 million doses of H1N1 -- also know as swine flu -- vaccine would be available by the end of October . On October 16 , CDC officials announced that only 28 million to 30 million doses would be available this month , because of manufacturing delays . Sens . Joe Lieberman , I-Connecticut , and Susan Collins , R-Maine , expressed `` strong concerns '' about the distribution of the H1N1 vaccine in a letter to Health and Human Services Secretary Kathleen Sebelius . Frieden also told reporters that while the H1N1 flu is still widespread across the country , some areas are seeing flu activity start to decrease . But he said the decrease is patchy , even within some states . He confirmed H1N1 is decreasing in Georgia , which was hit hard when schools reopened in August . Michigan schools were recently affected , with 117 schools still closed in the state , down from more than 240 last week , according to James McCurtis of the Michigan Department of Community Health . McCurtis said on the department 's Web site that most schools are closed because of high absenteeism . He said parents are keeping children with flu-like symptoms at home , which is what health officials have been recommending . CNN 's Saundra Young contributed to this report .
