5 year-old Brendan Campbell knows the painful routine. "If you don`t want it, your parents hold you down," he remembers. "It hurts bad. First you do one, then you do the other. Then you can`t walk." For Brendan, they`re painful memories of much-needed vaccinations. For health experts, they`re memories more kids should be having. Right now, only 71 percent of all toddlers get the vaccinations the CDC recommends. That`s compared to a national average of 75 percent. State health officials say there`s really no excuse to avoid the shots. They say the risk of side-effects is minimal and so is the cost. A round of shots only costs five dollars.
