The swine flu vaccine appears to work for adults with just one shot and within 10 days, a major boost to the widespread immunization campaign that officials are planning to protect people against the first influenza pandemic in 41 years, researchers reported.
Preliminary data from an Australian study found that a single standard dose could produce an immune response in more than 96 percent of recipients, and U.S. studies indicate that the protection occurs within eight to 10 days, scientists reported. The vaccine also appeared safe.
“This is very encouraging news,” said Health and Human Services Secretary Kathleen Sebelius as a briefing outlining the findings began, noting it means more Americans will be protected sooner than had been thought. “The vaccine we have purchased will go further and cover more people,” Sebelius said.
Previously, the government was insisting on up to three shots this flu season. However, you still cannot sue if the vaccine causes damage or death to you or one of your family.
