Obama: Americans should get swine flu shot

With a potentially deadly swine flu outbreak looming, President Barack Obama is urging Americans to take steps to prevent infection.

Obama was briefed Tuesday on the nation's preparedness for swine flu by senior officials, including Health and Human Services Secretary Kathleen Sebelius and Homeland Security Janet Napolitano. Following the meeting, Obama said the government is preparing across all levels, but all Americans have a role to play in the response.

"I don't want anybody to be alarmed, but I do want everyone to be prepared," he said.

The global swine flu epidemic first emerged in April, sickening more than 1 million Americans and killing about 500. More than 2,000 people have died worldwide. Health officials are preparing for a surge in cases this fall, and one White House report from a panel of experts suggests up to half the U.S. population could catch swine flu during a pandemic

Vaccine development is ongoing and is likely to be available by October. The president said the vaccine for swine flu — known as the H1N1 virus — would be voluntary, but said the government will "strongly recommend" that people get it.

Certain groups are more vulnerable to swine flu, including children under 2, pregnant women and people with health problems like asthma, diabetes and heart disease.

Like the seasonal flu, swine flu spreads through coughs and sneezes of people who are sick. Obama said there are common sense precautions people can take to lower their risk of infection, like washing their hands frequently and staying home if they feel sick.

"I know it sounds simple, but it's important and it works," Obama said.
