Will people need just one dose of H1N1 vaccine?

Preliminary studies show one dose of the H1N1 vaccine will be effective for healthy adults. We don't know for sure yet about older children, pregnant women and adults with chronic conditions, but we believe that one dose of vaccine will probably protect these groups as well. We also don't know yet about young children, especially children younger than 9. Previous experience with seasonal flu vaccine tells us that young children may still require two doses. At this point, the CDC has not changed its recommendations regarding the two-dose requirement for H1N1 vaccine for either adults or children. Please continue to check this site for updates as the studies continue and we receive new information.

The information has been released at the request of the SW Washington Public Health Incident Commander. For more H1N1 Swine Flu information, spend time at the Clark County Public Health Swine Flu website at
