U.S. military troops will begin getting required swine flu shots in the next week to 10 days, with active duty forces deploying to war zones and other critical areas going to the front of the vaccine line. Air Force Gen. Gene Renuart also [said] that as many as 400 troops are ready to go to five regional headquarters around the country to assist federal health and emergency management officials. The Pentagon has bought 2.7 million vaccines, and 1.4 million of those will go to active duty military. National Guard troops on active duty are also required to receive the vaccine, as are civilian Defense Department employees who are in critical jobs. Because I can compel people to get the shots, larger numbers will have the vaccine," said Renuart, commander of U.S. Northern Command. "They will, as a percentage of the population, be vaccinated more rapidly than many of us. So we may see some objective results, good or not, of the vaccinations." Shots will be doled out on a priority basis, with troops preparing to deploy first, followed by other active duty forces, particularly any who might be needed to quickly respond to a hurricane or other emergency. Inoculating the military is a key requirement of the Pentagon's emergency plan, as a way to ensure that troops are available to protect the nation. They also will be on tap to provide help to states if problems come up as the flu season continues.
