You may have thought the swine flu mania was over, but it's actually just beginning, and it's hitting children the hardest---just as health officials had feared. Five students in Pueblo schools were confirmed with the H1N1 virus, representing what health officials call the "tip of the iceberg," writes The Pueblo Chieftain. In Colorado Springs, 11News cites four other cases, including two in El Paso County school districts. State health officials, meanwhile, are telling people to get their flu shots---lots of them and as early as possible. If you want total coverage, you probably need three shots: one for the ordinary flu and two more, separated by a few weeks, for the swine flu. The regular shot is available now, according to 9News, and the H1N1 vaccines should arrive in Colorado in October. But not everyone will be able to get swine-flu shots: Supplies will be targeted at higher-risk patients, including pregnant women, caregivers of infants six months and younger, people suffering from asthma, diabetes, or heart disease, and students. Moreover, it's unclear how effective the swine-flu shot will be. That's why a group of children in Colorado are going to be among the first in the world to test a vaccine by Novartis, one of several drug manufacturers, reports The Denver Post.
