Given his heartbreaking experience, Kenny Flyte advises women who are expecting to act quickly if they feel sick.
"Go see your doctor," Flyte said. "Don't even play around."
Fauci said today that health officials "appear to be having no trouble getting people signing up as volunteers" for clinical trials expected to begin in August to test the vaccine.
The clinical trials for a vaccination are expected to be followed by a voluntary vaccine program, anticipated to begin mid-October.
That vaccine program would be limited at first to those most susceptible to the virus. Those first in line to receive the series of two shots would likely be children, teenagers, health workers and pregnant women. The vaccine would be purchased by the federal government and distributed to state and local health departments.
Youth have also been hard hit in the swine flu outbreak, making school district preparation key to prevention.
Earlier this month, federal, state and local health officials gathered at a swine flu summit to size up what needs to happen to prepare for and prevent a second round of swine flu illnesses at the beginning of the upcoming school year like the ones that hit the world this spring.
At that time, Health and Human Services Secretary Kathleen Sebelius called on all states to update their emergency plans, including ways to carry out a mass vaccination program.
"We want to start re-engaging the American public and our state and local and health and private business partners in making sure we use these summer months well to prepare for what could be a serious outbreak," Sebelius said. "If it doesn't happen, we'll be fortunate and this planning won't go to waste."
