Schools Nationwide Plan to Offer H1N1 Vaccination Clinics Hundreds of schools nationwide are establishing clinics to administer vaccines against the H1N1 virus, representing what could be the most widespread school vaccination effort "since the days of polio," the Associated Press reports. According to the AP, nearly 3 million students attend schools in districts where officials intend to offer the H1N1 vaccine when federal health officials begin distributing it in mid-October, and many more school districts are likely to follow suit.
