The Obama administration is beginning a new push Monday to get Americans to get the swine flu vaccine.
The government released several television and radio ads to counter the illness that has already infected millions.
The public service announcements target children and their parents, young adults and those in high-risk groups, such as people with asthma, the Washington Post reports.
The ads point out that the supply of the vaccine is increasing, with another 10 million doses expected this week.
"Getting vaccinated is the best way to protect yourself and your family against the H1N1 flu virus," Health and Human Services Secretary Kathleen Sebelius said. "Fighting the flu is a shared responsibility and it is up to all of us to help prevent the spread of the flu in your community."
The Centers for Disease Control and Prevention estimates around 22 million people have been infected with swine flu and 3,900 have died from the virus.
